A strong focus of EcoFlight's work is flying over different mining operations in the Rocky Mountain West. Working closely with national and regional groups, we document the exponential growth in resource extraction that is operating near and sometimes in and under established wilderness and proposed wilderness areas.

Much of the western landscape we work to protect is impacted by the outdated 1872 Mining Law, which even today allows the mining industry to buy valuable mineral bearing public lands for the set 1872 price of no more than $5 per acre. The law was enacted to encourage settlement and development of publicly owned lands in the West. Unfortunately, nearly 150 years later, long after the West has been settled, this mining law is being used to trump all other uses of public lands, even if those lands are the West’s most special places, even if the mines pollute clean water and devastate wildlife habitat.

On every flight, EcoFlight captures images that are then distributed to press and our conservation partners. By giving the aerial perspective to environmental issues, EcoFlight's priority is to support grassroots and national conservation groups in their endeavors to protect the great ecosystems of the West.
