HELENA, Mont. (AP) — U.S. Sen. Max Baucus said Thursday he is reintroducing his measure to extend conservation protections along the Rocky Mountain Front.

Baucus first proposed the Rocky Mountain Front Heritage Act in 2011, but it failed to clear the last Congress. Baucus, again advancing the bill, said he tied the announcement to the 100-year anniversary of the effort to establish what became known as the Sun River Game Preserve.
