To the east of the Mecca Hills Wilderness and southeast of Joshua Tree National Park lie the Chuckwalla Mountains. The Chuckwallas are more or less continuous with the Little Chuckwalla Mountains; together these ranges form an imposing range of mountains separating the Interstate-10 corridor from desert areas further south. Despite their proximity to the heavily traveled Interstate-10, the Chuckwallas carry with them an almost certainty of solitude and quiet.
