Horsetooth Mountain is a small mountain located 4 miles west of Fort Collins. The rock formation forming the summit of Horsetooth is often used as a symbol of Fort Collins. The name comes from its distinctive appearance to horse teeth. From the summit you can see on clear days Longs Peak and Mount Meeker.
