Dinosaur's climate is semiarid with temperatures averaging between 0°F to 30°F in January and 50°F to 100°F in July. Elevations within the park vary between 4,700 and 9,000 feet. Winter snow makes roads at higher elevations impassable while only light to moderate snow is found at lower elevations. Summer thunderstorms often cause heavy downpours and localized flooding, but may fail to dampen parched soils less than a mile away.

Split Mountain

Split Mountain, the name John Wesley Powell gave to one of the Dinosaur’s most recognizable features, is aptly named: over millions of years, the Green River has carved a canyon into the center of the mountain, splitting it in two.
