It is here that the Yampa River, the last natural flowing river in the Colorado River System, joins the Green River. This is home and critical habitat for the endangered peregrine falcon, bald eagle, Colorado pikeminnow, and razorback sucker. Indian rock art in Echo Park testifies to the allure these canyons and rivers had for prehistoric people.
The Park has a great museum/quarry where you can see this massive section of cliff face with all the dinosaur bones exposed. It’s crazy how many bones are pilled up in this one area. They have everything from brontosaurus bones to fossilized squid.
We camped down in the Green River Valley and before dusk took a pretty strenuous 4-mile hike up to the top of Split Mountain.
