The American West was settled in part by gold miners exploring a new frontier, and now modern-day prospectors are fighting to keep that tradition alive.

A group of miners began illegally dredging for gold this week in Idaho’s Salmon River to challenge what they call federal government overreach into the waterway, Reuters reported. They are protesting regulations by the EPA that forbid suction dredging and other mining in the river in order to protect the habitat of endangered fish.

“This is the United States of America, not the ‘United State’ of America. The feds can’t come in here like storm troopers and start running our lands and rivers,” organizer John Crossman, the head of the Southwest Idaho Mining Association in Boise, told Reuters.
