Convenient parking, Mormon Rocks


Visible from nearby Interstate 15 these large sandstone formations having been eyed by passing climbers for decades and despite the ease of access and proximity to a large population of climbers very little documented climbing has gone on here.

Numerous old bolts and the odd piton scattered about suggest climbing has gone on here since the 1950's but very little information is known about the early pioneers. These days few climbers frequent the area and popular activities here include scrambling, rappelling and off-roading.

The rock is a variable quality sandstone conglomerate not unlike that found at Devil's Punchbowl and Texas Canyon. Rock quality can vary from formation to formation and even on different sides of the same formation with the north-facing slabs tending to have the best quality rock.

As with all sandstone areas please refrain from climbing for 48 hours or so after a rain, and perhaps longer if it's not especially sunny or warm.

Getting There 

Drive Interstate 15, exit Hwy 138 (Abiel Barron Memorial Hwy) heading west at Cajon Junction. Cross under the railroad bridge and turn right just past the turnoff for Lone Pine Canyon Road. Those coming from the west on Hwy 138 will want to reverse the directions.

P1) Climb easy terrain to the first bolt about 30' up and then continue up the waterstreak using pebbles and cobbles past a distinct crux at the 7th bolt to finish on a large ledge with a small tree. P2) Continue up past 5 more bolts and then run it out on easy terrain to a large ledge with another set of anchors. It's easy to combine both pitches into one but the first pitch is the best.To descend make two single rope raps to the ground with a 60 meter rope.
