Marshall Mesa Loop

Traverse a wide-open landscape south of town that’s as rich in coal mining history (explained by excellent interpretive signs) as it is with Flatirons views. The land preserves a rare remnant of dry tall-grass prairie where wildflowers bloom through spring, summer and fall. The geology of this area is particularly special, with rippled rocks showing evidence of ancient seas and visible fractures resulting from the upthrust of the Rocky Mountains.
