Spilling Thought: A 28,000-acre mountain range that form the boundary between southwest #Montana and #Idaho, the #CentennialMountains Wilderness Study Area is some of southwest Montana’s wildest country. Designated as an Area of Critical Environmental Concern in 2006, it is considered an important corridor for wildlife movement, providing an east-west trending mountain range connecting the #Yellowstone Ecosystem with the rest of the northern #RockyMountains. Abundant wildlife in the Centennial Mountains include moose, elk, deer, wolverines, badgers, black bears, a wide variety of birds, and occasionally wolves and grizzly bears. About 60 miles of the 3,100-mile Continental Divide National Scenic Trail runs through the mountain range. Activities include hiking, horseback riding, camping, fishing, wildlife viewing and photography. Photo by Bob Wick, BLM (@mypubliclands). by usinterior
