"Interior Dept. Reaffirms Protection of National Monument in Montana"

"WASHINGTON — The Interior Department announced on Wednesday that the Upper Missouri River Breaks, a famous chunk of river in central Montana that holds a national monument designation, would remain fully protected by federal land-use restrictions.

The Montana site, which Lewis and Clark first explored in 1808, is the fourth so far among 21 land-based sites being evaluated at the request of President Trump by Interior Secretary Ryan Zinke that has been removed from consideration for changes — such as reduction in size or elimination.

The others no longer at risk are Craters of the Moon National Monument in Idaho, Hanford Reach National Monument in Washington and Canyons of the Ancients National Monument in Colorado."
