This case represents the second time this controversy has appeared before us. In 1986, the Pittsburg & Midway Coal Mining Company (P & M) filed an action in federal court seeking an injunction and declaratory judgment that the Navajo Nation lacked jurisdiction to impose its Business Activities Tax on the “source gains” from P & M’s South McKinley Mine.
First, the land area containing the mine was part of the Navajo Reservation. In Pittsburg & Midway Coal Mining Co. v. Yazzie,
Second, the Tribe argued the tribal abstention doctrine applied because the area was Indian country within the meaning of 18 U.S.C. § 1151. Because the district court did not reach this issue, we did not consider it in the first appeal. Instead, we directed the district court to address the issue on remand, which it has now done. The district court held the area in question was not Indian country, making it inappropriate to dismiss P & M’s complaint for failure to exhaust tribal remedies. We now reverse and remand for further factual findings by the district court.
I. BACKGROUND
The South McKinley Mine is located outside the Navajo Reservation in northwestern New Mexico near the Arizona-New Mexico border. The mine is directly adjacent to a companion mine located within the formal Navajo Reservation boundary. The mine consists of approximately 15,677.40 acres or 20 to 25 square miles. The parties have stipulated before the district court about the title of the surface and subsurface estates where the mine is located.
Five interests each have an ownership share in part of the surface title to the mine site area: (1) the United States holds title to 7,347.23 acres or approximately 47% in trust for individual Navajo allottees with the Bureau of Indian Affairs (BIA) acting as trustee; (2) non-Indian private parties including P & M hold title to 6,303.68 acres or 40%; (3) the Navajo Nation holds title to 1,131.46 acres or 7%; (4) the United States holds title to 830.94 acres or 5% as public lands managed by the Bureau of Land Management (BLM); and (5) the State of New Mexico holds title to 64.09 acres or less than 0.5%.
In contrast, three interests each own part of the subsurface coal estate: (1) the United States holds title to 8,178.17 acres or 52%; (2) Cerillos Land Company, the successor in interest to the Santa Fe Pacific Railroad, holds title to 7,430.14 acres or 47%; and (3) the State of New Mexico holds title to 64.09 acres or less than 0.5%. P & M has leased the right to conduct its mining operations from these various titleholders. None of the subsurface coal rights are owned by, or held
The Navajo Nation’s Business Activities Tax imposes a 5% levy on source gains, less certain deductions, derived from commercial activities within the Tribe’s jurisdiction. The Navajo Tax Commission administers the complicated statutory scheme. Navajo Trib. Code, tit. 24, §§ 401-445 (1985 Supp.). P & M has continued to pay this tax under protest during the pendency of this litigation.
Our remand instructions to the district court were:
We remand for consideration of whether some or all of P & M’s South McKinley Mine is within Indian country under 18 U.S.C. §§ 1151(b) or (c) and, if so, whether the court is obligated to abstain from initially deciding whether the Tribe can tax P & M’s source gains from the mine.
Pittsburg & Midway I,
18 U.S.C. § 1151. Indian country defined
Except as otherwise provided in sections 1154 and 1156 of this title, the term “Indian country”, as used in this chapter, means (a) all land within the limits of any Indian reservation under the jurisdiction of the United States Government, notwithstanding the issuance of any patent, and, including rights-of-way running through the reservation, (b) all dependent Indian communities within the borders of the United States whether within the original or subsequently acquired territory thereof, and whether within or without the limits of a state, and (c) all Indian allotments, the Indian titles to which have not been extinguished, including rights-of-way running through the same.
In its Memorandum Opinion and Order, the district court first concluded, “[t]he Tenth Circuit ruled the mine site is outside the reservation. The site does not fall within an Indian allotment. Therefore, the site is part of ‘Indian country’ only if it is a dependent Indian community.” Pittsburg & Midway Coal Mining Co. v. Watchman, No. 86-1442-M at 3 (D.N.M. June 11, 1993) (Memorandum Opinion). The district court then applied this court’s test for determining a dependent Indian community, Blatchford v. Sullivan,
After the court’s order, the Navajo Nation filed a motion to alter or amend the judgment pursuant to Fed.R.Civ.P. 59. Responding to this motion, the district court concluded:
The parties have stipulated that 47% of the surface right[s] of the mine are held in trust by the United States for Navajo al-lottees and an additional 7% of the surface is held by the Navajo Tribe. The allotments are Indian country by definition under 18 U.S.C. § 1151(e). However, I declined to find that the mine was in Indian country for purposes of removing this case to the jurisdiction of the Tribal Court, and I decline to alter or amend the judgment in response to defendants’ motion.
Pittsburg & Midway Coal Mining Co. v. Watchman, No. 86-1442-M at 1-2 (D.N.M. Jan. 19, 1994) {Rule 59 Order). Because the district court concluded the mine was not located in Indian country, it did not reach the issue of whether the tribal abstention doctrine or one of its three exceptions applied in this case.
On appeal, the Navajo Nation raises three issues. First, the Tribe argues the district court should have abstained pursuant to the tribal abstention doctrine until P & M had exhausted all its available tribal remedies. The Navajo Nation contends none of the three exceptions to the tribal abstention doctrine are applicable. Second, the Nation argues the district court erred in concluding that none of the South McKinley Mine site is
In response, P & M first argues the tribal abstention doctrine should not be applied because “the action is patently violative of express jurisdictional prohibitions.” National Farmers Union Ins. Cos. v. Crow Tribe of Indians,
II. PURPOSES OF THE TRIBAL ABSTENTION DOCTRINE
We begin our analysis with an overview of the purposes and policies behind the tribal abstention doctrine, placing the issues involved in the ease in the proper context. The Supreme Court originally articulated the tribal abstention doctrine in National Farmers, advancing a variety of policy reasons in support of the rule that a federal court should abstain until the tribal courts have had the initial opportunity to consider a particular matter. First, Congress’ long-standing commitment to tribal self-government and self-determination, including the development of independent tribal courts, supported the doctrine. Second, the orderly administration of justice would be advanced by allowing the tribal courts to develop a full record. Third, federal courts reviewing tribal court decisions would have the benefit of their expertise. National Farmers, 471 U.S.
We believe the tribal abstention doctrine applies throughout Indian country, not just on formal reservations.
This court and the Eighth Circuit have gone further by applying'the tribal abstention doctrine where no tribal court action had been filed prior to the federal action. See, e.g., Brown v. Washoe Hous. Auth.,
Our recent decision in Texaco provides a framework for our inquiry. We must “examine assiduously the National Farmers factors in determining whether comity requires the parties to exhaust their tribal remedies before presenting their dispute to the federal courts.” Id. We conclude the application of the tribal abstention doctrine here would serve the policies articulated in National Farmers and Iowa Mutual. We examine each policy in turn.1
First, the Supreme Court has recognized that Congress’ commitment to tribal self-government supports the tribal abstention doctrine. National Farmers,
The policy of tribal self-government is clearly implicated here. P & M’s lawsuit makes a facial, jurisdictional challenge to the Navajo Nation’s exercise of its taxing authority which is a basic attribute of its sovereignty.
The power to tax is an essential attribute of Indian sovereignty because it is a necessary instrument of self-government and territorial management. This power enables a tribal government to raise revenues for its essential services.... [I]t derives from the tribe’s general authority, as sovereign, to control economic activity within its jurisdiction, and to defray the cost of providing governmental services by requiring contributions from persons or enterprises engaged in economic activities within that jurisdiction.
Merrion v. Jicarilla Apache Tribe,
Second, the Court has recognized “the orderly administration of justice in the federal court will be served by allowing a full record to be developed in the Tribal Court before either the merits or any question concerning appropriate relief is addressed.” National Farmers,
[T]he existence and extent of a tribal court’s jurisdiction will require a careful examination of tribal sovereignty, the extent to which that sovereignty has been altered, divested, or diminished, as well as a detailed study of relevant statutes, Executive Branch policy as embodied in treaties and elsewhere, and administrative or judicial decisions.
National Farmers,
Third, the Court concluded later federal review would benefit from tribal court expertise. Id. at 857,
In summary, we hold the tribal abstention doctrine applies in this case. Our analysis of the National Farmers and Iowa Mutual policies leads us to conclude comity dictates that P & M exhaust its available tribal remedies before proceeding in federal court. The district court must abstain if the South McKinley Mine lies within Indian country.
III. EXCEPTIONS TO THE TRIBAL ABSTENTION DOCTRINE
We next consider whether any of the three exceptions to the tribal abstention doctrine are applicable. National Farmers,
' We believe this case is an appropriate candidate for the exercise of our discretion to decide an issue not reached by the district court. First, the applicability of the National Farmers exceptions were presented to and considered by the district court. However, the court did not decide this issue because of its initial determination the mine was not in Indian country. Second, this issue has been fully briefed on appeal. Colorado Interstate Corp. v. CIT Group/Equip. Fin., Inc.,
In announcing the tribal abstention doctrine, the Court also outlined three instances where it would not apply.
We do not suggest that exhaustion would be required where an .assertion, of tribal jurisdiction “is motivated by a desire to harass or is conducted in bad faith,” cf. Juidice v. Vail,430 U.S. 327 , 338,97 S.Ct. 1211 , 1218,51 L.Ed.2d 376 (1977), or where the action is patently violative of express jurisdictional prohibitions, or where exhaustion would be futile because of the lack of an adequate opportunity to challenge the court’s jurisdiction.
National Farmers,
The proper scope of the tribal abstention doctrine is a question of law we review de novo. Texaco,
P & M argues 18 U.S.C. § 1151 defines Indian country solely for criminal jurisdiction purposes. However, both the Supreme Court and this court , have concluded § 1151 defines Indian country for both civil and criminal jurisdiction purposes. The Court first came to this conclusion in DeCoteau v. District County Court, 420 U.S., 425,
IV. INDIAN COUNTRY
When applied to this case, these principles indicate if the South McKinley Mine site is located in Indian country, the district court must abstain until P & M exhausts all their available tribal remedies. We hold the mine is at least in part located in Indian country. We reach this conclusion based on the combination of two circumstances. First, the United States holds 47% of the mine site area in trust for individual Navajo allottees. These Navajo trust allotments are Indian country by definition under 18 U.S.C. § 1151(c). Second, the mine site and the surrounding area may constitute a dependent Indian community within the meaning of 18 U.S.C. § 1151(b).
Unfortunately, the factual record is not sufficiently developed for us to determine whether the mine site is part of a dependent ■ Indian community. Thus, we must remand once again for the district court to make this initial determination.
We do not believe these two definitions of Indian country áre mutually exclusive. When read together, they support our holding that the tribal abstention doctrine may apply in the instant ease. The combination of nearly half of the mine’s being located within individual Navajo trust allotments and the mine and the surrounding area’s being a dependent Indian community would sufficiently implicate Navajo interests to invoke the doctrine. Ultimately, however, the question of whether abstention is required depends on the district court’s factual determinations on the dependent Indian community issue:
A. TRUST ALLOTMENTS
We review de novo the district court’s legal conclusion the South McKinley Mine site is not within Indian country under 18 U.S.C. § 1151(c). Blatchford,
The plain language of 18 U.S.C. § 1151(c) defines Indian country to include: “all Indian allotments, the Indian titles to which have not been extinguished, including rights-of-way running through the same.” (emphasis added). Congress amended this statute to conform to the Supreme Court’s decision in United States v. Pelican,
As the Navajo Nation points out, the district court’s two orders in this case are difficult to reconcile. Initially, the court concluded, “[t]he site does not fall within an Indian allotment.” Memorandum Opinion, at 3.
There are at least two possible explanations for the district court’s two orders. First, the court may have concluded because the South McKinley Mine site did not fall within a single allotment, § 1151(c) did not apply. We have found no case law supporting this position, however. Second, perhaps the district court was implicitly suggesting the National Farmers policies were not sufficiently implicated in this case. If so, the court should have explicitly reached this conclusion. We reject the court’s “implicit suggestion” because it conflicts with our analysis in Part II of this opinion.
On appeal, P & M does not attempt to defend or reconcile the district court’s orders. Neither P & M nor any of the amici curiae dispute that Navajo allotments represent 47% of the surface area where the mine is located. Instead, P & M argues the South McKinley Mine does not fall within 18 U.S.C. § 1151(c) because neither the Navajo Nation nor any individual Navajo allottee holds title to any of the subsurface coal estate. P & M offers no citations in support of its rather novel theory, and we have been unable to find any, either. If we were to accept P & M’s argument, jurisdiction would depend on commercial transactions between the United States, New Mexico, the Navajo Nation, and various private parties. A particular parcel of land, or even an individual stick in the bundle of property rights, could suddénly change jurisdictions as a result of a single commercial transaction. This is an untenable prospect. Such a result would unnecessarily complicate already convoluted jurisdictional questions throughout the West. See generally Paul W. Gates, History of Public Land- Law Development (1968).
We hold that the 48 trust allotments comprising 47% of the surface area of the South McKinley Mine site are Indian country by definition under 18 U.S.C. § 1151(c). However, we believe the individual Navajo’s 47% interest by itself is not enough to trigger the tribal abstention doctrine.
As we discussed in Part II, the tribal abstention doctrine has its roots in comity. Federal courts should abstain when a suit sufficiently implicates Indian sovereignty or other important interests. We do not believe, however, the 47% stákehold of individual Navajo allottees, in and of itself, provides a sufficient nexus to require abstention in this lawsuit involving the entire South McKinley Mine.
B. DEPENDENT INDIAN COMMUNITY
We review de novo the district court’s conclusion the South McKinley Mine site was not part of a dependent Indian community under 18 U.S.C. § 1151(b). Blatchford,
1. COMMUNITY OF REFERENCE
The issue of the proper community of reference for dependent Indian community analysis under § 1151(b) is a question of first impression. In United States v. South Dakota,
The Supreme Court and the lower courts that have addressed dependent Indian community issues have done so in a variety of different contexts. The scope, size, and nature of what has been found to be a dependent Indian community within the meaning of 18 U.S.C. § 1151(b) do not provide much specific guidance. Large geographical areas have previously been determined to be dependent Indian communities. For example, the Court in United States v. Sandoval,
There are as many as twenty Indian pueblos scattered over the state, having an aggregate population of over 8,000. The lands belonging to the several pueblos vary in quantity, but usually embrace about 17,-000 acrés, held in communal fee-simple ownership....
Id. at 38-39,
We do not believe these cases support the district court’s conclusion that “[e]aeh ease cited in Blatchford assessed the status of a relatively limited area.” Memorandum Opinion, at 3. The existence of a dependent Indian community does not depend on the relative size of the geographical area.
The. ease law reveals at least two organizing principles useful for determining the community of reference. The first is the status of the area in question as a community. Several courts have applied the definition of community originally used in Berry v. Arapahoe & Shoshone Tribes, 420 F.Supp.
Basic to the definitions of “community” which we have reviewed is the existence of an element of eohesiveness. This apparently can be manifested either by economic pursuits in the.area, common interests, or needs of the inhabitants as supplied by that locality. Cohesiveness or common interests can be more necessary to the existence of a community than can mere density of population.
Morgan,
P & M argues the South McKinley Mine represents the logical area of reference because it has a use, purpose, and economic life distinct from the surrounding area. The common and ordinary meaning of community, however, connotes something more than a purely economic concern. A community is a mini-society consisting of personal residences and an infrastructure potentially including religious and cultural institutions, schools, emergency services, public utilities, groceries, shops, restaurants, and the other needs, necessities, and wants of modern life. See, e.g., Berry,
Second, dependent Indian community analysis focuses on the community of reference within the context of the surrounding area. In Blatchford, we examined the characteristics of Yah-Ta-Hey in McKinley County, New Mexico. Blatchford,
The district court described Yah-Ta-Hey as a rural and ‘readily identifiable residential and trading community’ including the commercial establishments at the intersection of U.S. Highway 666 and State Highway 264, a small ' housing subdivision known as Navajo Estates, and the surrounding area within three to five miles of the intersection. •
Id. at 548. We concluded Ya-Ta-Hey’s infrastructure and essential services were provided jointly by the City of Gallup, McKinley County, and the State of New Mexico. Id. at 548. Similarly, in Berry, the court looked to Riverton, Wyoming, as “the nearest community of any size” that provided necessary services for the lodge. Berry,
The Navajo Nation argues the entire Tsay-atoh Chapter should have been used as the community of reference. The resolution of this issue involves substantial factual determinations, making the district court the appropriate forum for its initial consideration. The Tsayatoh Chapter may prove to be the appropriate community of reference. However, there may also be a clearly identifiable community that includes the mine site but is smaller than the entire Tsayatoh Chapter. We leave this determination to the district court on remand.
2. THE BLATCHFORD TEST
In Blatchford, we described the standards defining a dependent Indian community. Blatchford,
Since Martine was decided in 1971, the Eighth Circuit has modified our test by adding several additional factors. In Blatch-ford, we implicitly adopted our sister circuit’s modified formulation of the appropriate inquiry. Id. at 546-49. We now explicitly adopt the Eighth Circuit’s four-prong test for determining what constitutes a dependent Indian community under 18 U.S.C. § 1151(b):
[W]hether a particular geographical area is a dependent Indian community depends on a consideration of several factors. These include: (1) whether the United States has retained “title to the lands which it permits the Indians to occupy” and “authority to enact regulations and protective laws respecting this territory,”; (2) “the nature of the area in question, the relationship of the inhabitants in the area to Indian tribes and to the federal government, and the established practice of government agencies toward the area,”; (3) whether there is “an element of cohesiveness ... manifested either by economic pursuits in the area, common interests, or needs of the inhabitants as supplied by that locality,”; and (4) “whether such lands have been set apart for the use, occupancy and protection of dependent Indian peoples.”
South Dakota,
We believe the district court must assess the evidence and reach conclusions on such issues on remand.
Y. CONCLUSION
We remand to the district court on two issues. First, the district court must determine the appropriate community of reference for its dependent Indian community analysis. Second, after deciding that threshold issue, the district court must make specific, detailed factual findings on each of the four prongs of the dependent Indian community test. If the court concludes the South McKinley Mine site and the surrounding area constitutes a dependent Indian community, it must abstain until P & M exhausts all its available tribal remedies.

. Of course, if the entire mine was located on Navajo trust allotments, there would be no question about the doctrine's applicability. Similarly, abstention would apply if the controversy only involved the 47% of the mine site area of the trust allotments. In other words, we believe the Navajo Nation has the authority to apply its Business Activities Tax to the source gains from the 47% portion of the South McKinley Mine that lies within the individual Navajo trust allotments. We intentionally offer no opinion about what percentage threshold of Indian interests would be necessary to trigger abstention. The resolution of that issue can await another day.

After reviewing several dependent Indian community cases, the district court reached the following conclusion: "The case law leads me to conclude that it is appropriate to assess the status of the mine site rather than the larger area of the Tsoyatoh (sic) Chapter.” Pittsburg & Midway Coal Mining Co. v.

. Several state courts in the East have adopted an alternative test because of the historical differences in the relationship of the federal and state governments to Indians in the Eastern and Western United States throughout this nation's history. The competing test holds that a dependent Indian community exists if: (1) there is a bona fide tribe of Indians; and (2) the tribe has inhabited the land, has had “Indian title” to it since 1790, and has maintained the same status and nature of its occupancy from 1790 to the time the cause of action arose. State v. Dana,
. Amicus Ray Powell, the Commissioner of the Public Lands for the State of New Mexico, argues the Navajo Nation has no authority to apply its Business Activities Tax on state trust lands. As noted above, New Mexico holds title to 64.09 acres or less than 0.5% of the mine site area. We have chosen not to address these arguments on appeal. Mr. Powell should advance them first to the district court on remand.
