Visited in 2019. Understand this is only worth visiting if you are willing to go for a ~3 mile round trip hike on a mildly rugged trail. The view from the parking lot (at the end of a long paved road) isn't much. If you are willing to make the walk, the view from the end of the trail is sensational. You can't actually see the confluence of the Green and Yampa rivers (it's hidden behind Steamboat Rock) but the contortion of geologic layers is sensational. Note that it's a desert hike. Bring your own water, lots of it because even if it's not scorching hot (it wasn't the day I went), the air will suck the moisture right out of you.
Note this is a separate entrance to Dinosaur National Monument (the main entrance/visitor center is in Vernal, UT). A pass to the main monument should also get you in here.
Fun fact: despite this being the geographical center of nowhere, I had a cell signal. Probably from a tower 30 or 40 miles away.
