Hanksville to Rock Springs: A 300-Mile Desert Odyssey

Leaving Hanksville, UT (elevation 4,300 ft), you immediately enter the vast San Rafael Desert, a landscape sculpted by the erosive power of the Muddy Creek. The road, mostly US-24 then I-70, ascends from the Colorado Plateau to the Wyoming Basin, crossing the geologic boundary between the Basin and Range and the Rocky Mountains. This 300-mile drive typically takes 4.5 to 5 hours of pure driving, but plan a full day to explore.

The dominant features are the San Rafael Swell – a massive anticline visible from I-70 – and the Book Cliffs, which run parallel to the highway for over 200 miles. The route crosses the Green River at the town of Green River, UT, a hub for melon farming. This area is part of the Colorado Plateau, a region that includes Canyonlands and Arches National Parks, both UNESCO World Heritage Sites. The San Rafael Swell itself is a candidate for UNESCO status, known for its desert bighorn sheep and ancient rock art.
