Description

Mount Marie Louise and her sister The Pinnacles lie northwest of Lake Arrowhead. Although not visible from the usual route, the peak and its pinnacles stand out dramatically when viewed from the west. It has views of the Hesperia area and the Mojave Desert beyond, Silverwood Lake and multiple HPS peaks including Cleghorn, Luna, Round and Rattlesnake.

Although short, Route 1 is an interesting and gratifying cross country route that passes through interesting terrain and has some rock scrambling to the somewhat brushy summit.

Follow a usually ducked route up the gully, heading generally north through boulders until west of bump 5398′.
Ascend the sometimes brushy ridgeline northwest to the summit, which is the farthest north of the rocky outcrops.
