The situation

What’s happening to Chaco Culture

A thousand years ago, Chaco coordinated civilization across tens of thousands of square miles. Today its great houses are surrounded by thousands of oil and gas wells, with more permits approved every month. The 10-mile buffer zone that kept the industry at bay is being dismantled.

Sources and methodThe situation, timeline, and threats: the MTJP threatened-lands record for Chaco Culture, with per-item sources. Group crews and program ratios: IRS Form 990 via ProPublica Nonprofit Explorer, latest filed year, EINs on each group’s profile. Which groups are listed for this place: a group is listed only under a sourced fact, and each chip opens its source. Local means headquartered in the state (the group’s own site, else the legal domicile on its 990) or the place named in its mission on its latest 990. In the fight means a case over the place naming it (the court docket), its own comment on a decision about the place (regulations.gov), an editors’ link with its source or its own page approved by a person here, or events on its own calendar held at the place. No fact, no listing. Org-reported figures are always labeled. Data verified as of 2026-10-07. No group pays to be listed on this page or for where it sits.
