Changing Corners stands as an inviting yet technically engaging single-pitch trad route on the west face of School Rock in the San Bernardino Mountains. From the moment your fingers find their first holds on Small Wooden Babies, the climb compels you to read the rock carefully, moving deliberately through a series of right-facing corners that demand both focus and finesse. The initial chimney-like corner eases you into the rhythm, leading toward a small roof that guards the more demanding moves ahead. Navigating around 10 feet to the right, you enter another clean right-facing corner where solid hand- and footholds provide confidence as you work upward.

This 50-foot line blends straightforward movement with a touch of route-finding flair uncommon in shorter climbs. The rock has a firm texture, offering reliable friction underfoot and a moderate challenge for climbers comfortable with moderate trad grades. Protection varies from a single bolt near the lower section to several pieces of gear up to 2 inches in size, ending in two-bolt anchors. These fixed points are reassuring but still call for careful gear placement, especially as the route tightens in the upper corner.

Located in the Running Springs area, the climb benefits from a setting that is rugged yet accessible, framed by the towering San Bernardino range. Clear skies and gentle mountain breezes make the approach and climb refreshing, especially in the cooler months. Given the route’s west-facing orientation, afternoons often provide ideal light and warmth, while mornings may chill the rock to a brisk hardness, affecting friction and sensitivity.

Approach is straightforward but requires a keen eye for the right path amid mixed forest and rock outcrops. The trail to School Rock offers a mild ascent with a blend of loose gravel and packed dirt; expect about a 20-minute hike from the nearest parking. Bringing sturdy shoes with good tread is essential, as footing can feel uncertain on the approach.

Changing Corners suits climbers looking to blend navigation with climbing technique—perfect as a warm-up in the area or a confidence booster for trad novices stepping into corner cracks. To maximize the experience, carry adequate hydration and gear to protect fingers and hands from scraping edges. Cooler seasons reduce heat exposure, while spring showers can slick the lower sections, creating a need to gauge conditions carefully before committing.

In summary, Changing Corners offers a compact taste of San Bernardino trad climbing. It balances rock that challenges precisely where it counts with a friendly length that fits well into a half-day outing. Even with its modest rating, climbers will find satisfaction in the route’s thoughtful protection and the rewarding flow between cracks and corners. Whether you’re topping out under the clear skies or simply appreciating the quiet mountain air, this route rewards those who approach it prepared, steady, and ready for a focused climb.
