| Castle Valley, Utah, was once a sea. |
Castle Valley is a scenic viewpoint on Interstate 70 across Utah that connects Interstate 15 with Grand Junction, Colorado. (A town by the same name is about 20 miles away.
But once upon a time, Castle Valley was part of a great sea,
dating back to before the Jurassic era. It was a tropical forest with giant
dinosaurs roaming the land. Over the millennia, other plant and animal life
built up into the colorful layers of rock, creating coal and natural gas pits in
the process.
This area is part of the geologic San Rafael Swell, where
erosion has exposed layers of the earth’s crust, giving us a glimpse of what
the area was like millions of years ago.
Views stretch for dozens of mils from this viewpoint, which
offers picnic tables and vault toilets.
