The new boardwalk at the tracksite.

The Bureau of Land Management officially dedicated for the Red Gulch Dinosaur Tracksite on May 22, 2002.

The dedication highlighted the new boardwalk, interpretive signs, picnic tables, benches, trails, an upgraded access road and graveled parking for up to 15 cars and 3 buses.

The Red Gulch Dinosaur Tracksite is the largest tracksite in Wyoming and one of only a few worldwide from the Middle Jurassic Period (160 million to 180 million years old). Until these tracks were discovered in 1997 most scientists thought the entire Bighorn Basin, and most of Wyoming, was covered by an ancient ocean, the Sundance Sea. The tracks were made at the shoreline by two-legged dinosaurs around 167 million years ago.

The tracksite is located on U.S. Highway 14, approximately 10 miles east of Greybull, Wyo. (or four miles west of Shell) to the Red Gulch/Alkali National Back Country Byway turnoff. Head south on the byway approximately five miles.
