Red Slate Mountain holds a quiet yet undeniable claim on the High Sierra skyline, visible from many surrounding summits as a distant, snow-speckled peak that beckons with a raw, primal sense of adventure. To the south, this mountain appears almost sculpted from deep red scree slopes, vast and forbidding. But approaching from the north reveals its true alpine character—a sharply defined silhouette pierced by a high, diagonal couloir carved into its face that draws climbers seeking a mix of technical challenge and breathtaking exposure.

The journey to Red Slate begins at Convict Lake, where the trail guides climbers along the lake’s shimmering northern shore before navigating the rugged corridors of Convict Canyon. This narrow passage winds between jagged peaks and steep ridges, adding an element of wild, understated beauty to the approach. The trail ends at Mildred Lake, a perfect campsite surrounded by towering rock faces, making it an ideal base for acclimatizing before pushing further south toward the mountain’s base.

Climbing here is as much about the process as the summit itself. The north couloir, rated WI2, is the classic line—its icy corridors offering a sustained mixed climb framed by the grandeur of the surrounding peaks. While the route count is modest, each climb underscores the area’s alpine spirit, demanding respect for the unpredictable elements and rewarding with immense satisfaction. The mountain’s elevation of 13,156 feet means weather can shift swiftly, so timing is crucial—summer and early fall provide the most reliable window for an ascent when snowfields and ice soften just enough to make the climb feasible.

The rock and ice environment calls for a well-rounded skill set and solid preparation. Approaching via Convict Canyon means hikers and climbers should be ready for steep scrambles, variable footing, and potentially cold nights if camping near Mildred Lake. Essentials include layered clothing for temperature swings, reliable navigation tools, and climbing gear suited to alpine mixed routes—ice tools, crampons, and a cautious approach to protection placements in often loose or icy rock.

For those drawn to experience classic High Sierra climbs in their purest form, Red Slate provides a singular setting that feels both remote and inviting—offering a careful balance between challenge and exhilaration. It’s a place where the wilderness feels immediate, views unfold without distraction, and every step on the trail or pitch demands focus and respect. Whether you’re setting foot on the icy couloir or simply savoring the broad panoramas from the trail below, Red Slate Mountain is a destination that embodies the spirit of true alpine adventure.

Planning a trip here means considering the logistics carefully: from the 4,800-foot elevation gain starting at Convict Lake to the potential camping spots around Mildred Lake, every detail enhances the journey. Weather averages favor summer through early fall climbing, though sudden storms are always a possibility, so remain vigilant and plan accordingly. Embrace the ruggedness and solitude of this High Sierra giant and prepare for an alpine outing that lingers in memory long after the descent.
