Bum Steer stands out on the Claim Jumper Wall with its steady climb that snakes up a broad face, inviting climbers who seek both technical moves and expressive line choice. Starting with a series of positive, juggy edges, the route gently encourages you into the rhythm before guiding you left towards a rounded arete. The initial section feels approachable, yet each move demands focus, setting the stage for the climb’s defining moment. Around the fifth bolt, the route hits a clear crux—here, pushing straight up is an option but considerably more taxing. Opting left through this sequence offers a balance of challenge and reward, testing finger strength and precise footwork.

Once beyond the crux, the rock opens up. Holds grow noticeably larger and more generous, but the spacing between bolts stretches out, which means your confidence both in protection and movement must upkeep. This section brings a gratifying sense of flow, the occasional breath of wind and distant calls from the forested landscape reminding you of the wild setting this climb inhabits. The final moves bring a rush of exhilaration, as the climb trades tension for confidence and the anticipation of reaching the anchor.

At 60 feet, the single pitch is straightforward in length, but it packs a layered experience into its span. The quality stainless steel bolts, newly replaced in 2019, provide a secure frame, allowing climbers to focus on the technique without doubt in the gear’s reliability. Bum Steer is an appealing option for sport climbers familiar with 5.10a challenges and those ready to sharpen their skills on a route that commands steady control and strategic resting points.

Claim Jumper Wall occupies a quiet corner of the San Bernardino Mountains, within the Holcomb Valley Pinnacles—an area where rugged beauty, forested trails, and climbing routes converge. Approaching the wall rewards with shaded forest paths and fresh mountain air, carrying you close to the rock where adventure begins. The route’s position on the face provides intermittent shade throughout the day, making it a solid afternoon pick, especially during warmer seasons when sun exposure can become taxing.

Climbers venturing here should prepare with reliable sport climbing shoes, chalk to keep hands dry through the crux, and a well-packed rack centered around a sport setup, given the well-spaced bolts in the upper section. Staying hydrated is essential, as the approach, while not overly long, carries the dry air typical of this Southern California zone. Angie locals recommend visiting in spring or fall for optimal temperature and stable weather.

The descent follows a straightforward rappel from the anchor, with clear lines down to the base. Take care during this phase; the rock can feel slick if early morning moisture lingers or after rainfall. Staying alert enhances a clean, safe end to the climb, allowing you to reflect on the route's demands amidst evolving views of the Big Bear area.

Whether you are aiming to push your redpoint limits or simply immerse yourself in technical sport climbing with solid protection, Bum Steer delivers an interactive encounter with the rock and environment that motivates focus while honoring the rawness of the California high country.
