Trappers Point, a few miles west of Pinedale, is both an archaeological site and an active wildlife corridor. The mesa and surrounding terrain form a natural bottleneck that has funnelled pronghorn antelope migrations for thousands of years. Archaeological digs have uncovered evidence of systematic pronghorn hunting here going back at least 5,000 years.
The site is also one of the best places in Wyoming to witness the pronghorn migration itself. Pronghorn move through in large numbers twice a year — north in spring and south in autumn — and the passage through Trappers Point concentrates them into a visible flow. The migration is one of the longest land animal migrations in the Western Hemisphere, rivalling the Serengeti wildebeest in its scale relative to the landscape.
