Edwards AFB Memorial Service Set for June 29 to Remember B-52 Crash Victims

The National Parks Conservation Association (NPCA) has filed a motion for a preliminary injunction to immediately stop unlawful mining activities at the Colosseum Mine within Mojave National Preserve. The mining operation, which ended in 1993, was in the final stages of reclamation by the National Park Service when the Trump administration approved new mining in April 2025.

Recent grading, bulldozing, and road construction have caused documented, irreparable damage to the fragile desert landscape and restricted public access to the preserve. The NPCA, represented by Earthjustice, filed a lawsuit in April challenging the administration's decision, alleging violations of federal laws protecting national parks from harmful mining impacts.

The injunction request urges the court to protect this environment, which Congress designated for perpetual preservation under the 1994 California Desert Protection Act. Chance Wilcox, NPCA's California Desert Program Manager, described the situation as gut-wrenching, noting that parts of the Clark Mountains are being stripped bare.

Katrina Tomas, an Earthjustice attorney, emphasized that bulldozing and mining will irreversibly harm one of America's most treasured public places and that the Colosseum Mine is proceeding in violation of national environmental laws. The NPCA is seeking immediate court action to halt the destruction before it is too late.

The National Parks Conservation Association (NPCA) filed a motion Tuesday for a preliminary injunction to immediately stop mining operations at the Colosseum Mine within Mojave National Preserve, a unit of the National Park System located near Amboy in Kern County, California.

Mining at the Colosseum Mine ended in 1993, and the National Park Service was in the final stages of reclaiming the site for public use. However, in April 2025, the Trump administration reversed course and approved new mining at the location.

Recent activity including grading, bulldozing, and road construction has caused documented, irreparable damage to the fragile desert landscape and has restricted public access to the preserve.

The NPCA, represented by Earthjustice, filed a lawsuit in April 2025 challenging the administration's decision to allow operations to resume, alleging violations of multiple federal laws that protect national parks from harmful mining impacts. The motion for an injunction asks the court to intervene to protect this desert environment, which Congress designated for perpetual preservation under the 1994 California Desert Protection Act.

“What’s happening right now at Mojave National Preserve is gut-wrenching,” said Chance Wilcox, NPCA’s California Desert Program Manager. “To see parts of this landscape, in the heart of the Clark Mountains, being stripped bare and graded down to dirt is hard to put into words.

We can’t sit by and allow irreparable damage to change this place that was promised to future generations, and that’s why we’re urging the court to step in to protect the park now.”

Earthjustice Attorney Katrina Tomas added, “Bulldozing, road construction, and mining within the Mojave National Preserve will irreversibly harm the desert landscape in one of our most treasured public places. The Colosseum Mine is proceeding with operations despite being in violation of national environmental laws.

We’re seeking a preliminary injunction to halt this destruction before it’s too late.”

The Colosseum Mine is located in the Clark Mountains within Mojave National Preserve. The NPCA's legal action seeks to prevent further environmental harm while the underlying lawsuit proceeds.

The National Parks Conservation Association (NPCA) has filed a motion for a preliminary injunction to immediately halt unlawful mining operations at the Colosseum Mine within Mojave National Preserve, a unit of the National Park System. The filing, made on June 24, 2026, in Los Angeles, seeks to stop further damage to the fragile desert landscape in the Clark Mountains near Amboy, California, in Kern County.

Mining at Colosseum ceased in 1993, and the National Park Service was in the final stages of reclaiming the site and returning it to public use. However, in April 2025, the Trump administration reversed course and approved new mining activity.

Recent grading, bulldozing, and road development have caused documented, irreparable harm to the desert environment and have limited public access to the preserve.

The NPCA, represented by Earthjustice, filed a lawsuit in April 2025 challenging the administration's decision, alleging violations of multiple federal laws designed to protect national parks from harmful mining impacts. Through the request for an injunction, the NPCA is asking the court to intervene to protect the area that Congress designated for perpetual preservation under the 1994 California Desert Protection Act.

Chance Wilcox, NPCA's California Desert Program Manager, expressed deep concern, stating that witnessing parts of the landscape being stripped bare and graded down to dirt is gut-wrenching. He emphasized that the organization cannot allow irreparable damage to alter a place promised to future generations and is urging the court to step in immediately.

Katrina Tomas, an Earthjustice attorney, added that bulldozing, road construction, and mining within the preserve will irreversibly harm the desert landscape in one of the nation's most treasured public places. She noted that the Colosseum Mine is proceeding with operations despite violating national environmental laws and stressed the need for a preliminary injunction to halt the destruction before it is too late.

The National Parks Conservation Association (NPCA) filed a motion for a preliminary injunction on Tuesday, June 24, 2026, in an urgent effort to stop unlawful mining operations at the Colosseum Mine within Mojave National Preserve. The preserve, located near Amboy in Kern County, California, is a unit of the National Park System.

Mining at the Colosseum site ceased in 1993, and the National Park Service was nearing completion of reclamation work to restore the area for public use. However, in a significant policy reversal, the Trump administration approved new mining activities at the site in April 2025.

Recent grading, bulldozing, and road construction have caused documented, irreparable damage to the fragile desert landscape and have restricted public access to the preserve. The NPCA, represented by Earthjustice, filed a lawsuit in April challenging the administration's decision, alleging violations of multiple federal laws designed to protect national parks from harmful mining impacts.

The motion for an injunction asks the court to intervene immediately to protect this desert environment, which Congress designated for permanent preservation under the 1994 California Desert Protection Act. Chance Wilcox, NPCA's California Desert Program Manager, described the situation as "gut-wrenching," noting that parts of the Clark Mountains are being stripped bare and graded down to dirt.

Katrina Tomas, an Earthjustice attorney, emphasized that bulldozing, road construction, and mining will irreversibly harm the desert landscape in one of America's most treasured public places, and that operations are proceeding despite violating national environmental laws. The court's decision on the injunction is pending.

The NPCA's action underscores the ongoing conflict between conservation efforts and resource extraction in protected areas. The outcome of the injunction request could set a precedent for how mining claims are handled within national park units.
