"Lost on the Horizon offers an accessible, single-pitch trad climb weaving across the Onyx Summit Crag’s face. With smart protection placements and a strategic rightward traverse, it’s ideal for climbers ready to explore easy but engaging routes in the San Bernardino Mountains."
Lost on the Horizon offers an approachable yet satisfying climb on the Onyx Summit Crag, making it an inviting choice for climbers eager to explore the high country of California’s San Bernardino Mountains. The route unfolds over a single 60-foot pitch, trading steep intensity for a smart, circuitous path that seeks out the face’s natural weaknesses. Beginning on a face-to-thin crack, the climb quickly encourages a rightward journey across the rock, moving steadily towards a bold arête that demands careful but measured movement. The rock underfoot and palms here carries the heat of the Southern California sun but offers enough texture to steady your progress as you sling gear and clip bolts.
This line takes advantage of the terrain’s quieter spots, inviting climbers to build their own rhythm. The traverse right after the arête opens up options — you can press upward to the bolt-protected Big BM or keep moving laterally for an easier finish. This flexibility means it suits both climbers building confidence in trad placements and those looking for a mellow adventure with a touch of exposure. The route’s protection calls for gear up to 1 inch, combined with a generous set of slings—essential for safely managing the traverses and anchors spread along the way.
Aside from its tactical climbing, the climb’s setting punctuates the experience. The surrounding forested slopes breathe a fresh pine scent, and distant peaks frame the horizon, reminding you why the San Bernardinos are worthy of any day's effort. The rock face quietly challenges while the environment encourages focused ascent—it’s a place where nature feels alive with energy, almost nudging you onward without force. For anyone targeting a crisp, accessible trad climb with a strategic edge, Lost on the Horizon offers a clear invitation.
Given its moderate rating of 5.8 and single pitch length, this climb is an excellent entry point to trad climbing in the area. Preparation is straightforward: solid footwear with reliable edging capability, hydration for the sunny, exposed sections, and durable slings to navigate the crag’s traverses will make your day smoother. Arrive early in the day to catch cooler temperatures and avoid the afternoon sun warming the rock, especially in summer months. Access is via well-marked trails from Highway 38, with Onyx Summit providing a dramatic backdrop as you gear up. For those seeking a short, engaging climb paired with scenery and a chance to hone their technique, this route fits the bill.
Watch your sling placements carefully during traverses—the anchors can be spaced widely, and the rock can feel compact. Sun exposure means dehydration is a concern, so bring enough water and pace yourself through the climb. Loose rock is minimal but scout each hold carefully on the face.
Start early to beat the heat on sun-exposed sections.
Ensure you have plenty of slings to protect the traverses safely.
Approach via the trailhead off Highway 38; expect about a 20-minute hike to the base.
Wear shoes with solid edging; the route mixes face climbing and thin cracks.
Bring trad gear up to 1 inch, several slings for protecting traverses, and be prepared to clip bolts on the upper face and anchors. Lots of slings will aid in managing the line's varied protection points.
