Twentymile Wash Tracksite

The Twentymile Wash Dinosaur Tracksite is in the Grand Staircase Escalante National Monument and is about twenty miles from the town of Escalante. Over 1,000 tracks are present at the site. Large bipedal dinosaurs made the tracks. The tracks are about twenty inches long and both trackways and tail drags are present. Tail drags are rarely seen as dinosaurs used their tails primarily for balance and did not rest on them. The dinosaur tracks at Twentymile Wash are not indented but can be identified as darker fillings on the underlying sandstone. The tracks are found in the Escalante member of Entrada sandstone. This member has a white to light gray appearance with a very slight yellow to green tint and is quite photogenic. There are a great many cavities present in the sandstone which add to the interest. More information on the tracksite can be found here.

Getting there

I suggest you stay in either Escalante or Boulder, Utah, or car camp in the Grand Staircase Escalante National Monument. You'll need a free permit from the BLM to camp in the area. It is illegal to camp at nearby Devil's Garden. Here are directions from Escalante:

Shooting Tips

You may want to bring a spray bottle filled with water. If you wet the tracks they will be more visible. It is illegal to excavate/remove tracks from the site. Do not sweep sand off the tracks, or make rubbings or castings of them. The site will photograph well within a few hours of both sunrise and sunset. The site is quite close to Devil's Garden which could be photographed on the same day.
