A LAND BEFORE TIME

Meet America's Real Jurassic Park

Here the Green and Yampa Rivers meet, carving an endless maze of canyonways and desert oases. Abundant fossil remains of Jurassic period dinosaurs stud the sandstone faces. Early Native American communities carved huge petroglyphs and pictographs on the steep cliffs. The rugged and varied terrain also served as hideouts for Butch Cassidy and other infamous bandits.

The future of this living museum is in question as drilling interests press to open adjoining lands for industrial development.
