Traveling south from I-70, the terrain begins to exhibit the erosion that carved this corner of Utah into some of the most captivating bare-rock country in North America. Part of the credit goes to the muddy Colorado River, snaking along 2,000 feet [609.6 meters] below the 5,900-foot [1,799.3-meter] overlooks in Dead Horse Point State Park (+1 435 259 2614. Adm. fee). Stop at the Visitor Center to pick up trail information and ask about ranger-guided walks (evenings May-Sept.). The park’s small museum traces the region’s complicated geological heritage.
The Colorado and Green Rivers corkscrew south through Canyonlands National Park (+1 435 259 7164. Adm. fee), merging at The Confluence and cutting the park into three districts named for their dominant theme: the lofty Island in the Sky mesa; the wilderness of sandstone spires in The Needles; and The Maze, a nearly inaccessible labyrinth of canyons.
From Utah 313 take The Neck entrance road into the park’s Island in the Sky district and Grand View Point Overlook, a deep panorama of red rock sandstone towers, bald mesas, sheer drop-offs, and dead-end canyons far below. The 6,080-foot-high [1,853.2-meter-high] ledge plummets 1,200 feet [356.8 meters] to the rim of Monument Basin, where rock towers rise 300 feet [91.4 meters]. For a glimpse of the Green River’s placid flow through Stillwater Canyon, backtrack to the Upheaval Dome turnoff and take the gravel road to the Green River Overlook.
There’s a tree-shaded picnic spot at the end of the road to Upheaval Dome. The mile-wide, 1,500-foot-deep [457.2-meter-deep] crater is either the eroded core of a primordial salt dome or a meteor impact crater. On the way back to the highway, stop and take the easy half-mile [0.8-kilometer] loop trail to Mesa Arch, which passes through a magical little forest of gnarled juniper and pinyon.
