Approximate location — plotted from published sources, not a site visit, and not a guarantee of access.
Near Stovepipe Wells in Death Valley National Park, Mosaic Canyon opens from a gravel parking area into polished Noonday Dolomite narrows and natural breccia mosaics. Many hikers turn around in the first half-mile of slippery marble; longer routes meet dryfalls and boulder jams. Sedan-passable 2.3-mile dirt road; national park entrance fee applies.
