Canyons are inherently risky. Flash floods occur without notice on sunny days. Technical skills & surrounding topography knowledge required yet does not eliminate risk.
Overview: Located in the southwestern Cottonwood Mountains resides this popular canyon for pic taking, day hikeing, and backpacking. If you like marble, narrows, rock art, or all, put Marble Canyon high on your list. It is claimed that the ancient petroglyphs that adorn the canyon walls (both on the drive in and hike) rank among the most elaborate and extensive in all of Death Valley. As of this writing for my posted trip log dated 2/13/10, our hiking group only viewed a couple of petroglyph panels located ~2.0mls to 2.2mls in at way point N36.60982 W-117.34316;
This hike description takes you through the most scenic Lower Marble Canyon Narrows #1 & #2 (ending at 1.6 miles in). There are actually three narrows, the 3rd starting at 4.0 miles in. We hiked in to a stopping point at 3.2 miles in. Unless you are planning a backpack trip through this 10.7 mile canyon to end at Goldbelt Spring- Camp/Road, I recommended that you day hike in to the above mentioned petroglyph panel site and then turn back.
