The mountain rises abruptly north of Mountain Pass and Interstate 15 to an elevation of 7,933 ft (2,418 m), which is the highest point of the Mojave National Preserve and the Mojave Desert ranges.[5] Creosote bush (Larrea tridentata), scrub and Joshua tree (Yucca brevifolia) forests grow on the foothills of the mountain while single-leaf pinyon pine (Pinus monophylla), Utah juniper (Juniperus osteosperma), and white fir (Abies concolor) grow on the sky island at the highest elevations.[6] Clark Mountain is also a world-class rock climbing area developed by Randy Leavitt in 1992.It has been described as containing the best limestone climbing in America and includes the world's first-ever 9b (5.15b) route, Chris Sharma's Jumbo Love (2008).[7] In 2022, French climber Seb Bouin, added a direct start to Jumbo Love to create Suprême Jumbo Love, which at 9b+ (5.15c), became the hardest sport climb in North America.
