Located just right of the prominent Left Dinosaur Crack, this single-pitch trad climb stands out with its early crux—a dynamic sequence on solid rock that tests your ability to make use of an adjacent boulder for added leverage.

Approaching Choss-o-saurus from the Cattle Pocket and Corridors area, you find yourself immersed in the stark beauty of the Alabama Hills. The granite slabs here bear witness to wind and sand, their weathered edges catching the light as shadows stretch across the landscape. Despite the raw, rough nature of the rock, the route is well-equipped: nine bolts are strategically placed, but a handful of cams—particularly in sizes from .75" to 3"—are essential to bridge the gaps safely. Top-out gear includes musky hooks, cautioning climbers to plan rope management carefully.

For those drawn to classic trad routes with a touch of unpredictability, Choss-o-saurus offers a pragmatic adventure.

The approach is short and straightforward, making this climb an accessible yet spirited choice for a morning session before tackling other big lines in the area.

Under the wide-open skies of California’s Sierra Eastside, Choss-o-saurus provides not only technical challenges but a chance to engage directly with nature’s grittier side. The surrounding terrain is arid, with desert winds shaping both landscape and mood. This route invites climbers to embrace a hands-on experience where calculated risks and reliable gear go hand in hand. Whether you’re fine-tuning your placings or savoring the quiet views, the line offers an authentic slice of Alabama Hills climbing that blends exposure with approachability.

Planning your climb around early morning or late afternoon avoids peak sun, as the wall faces southwest and heats up rapidly in midday hours. The descent is straightforward—walk off westward back to established trails—but loose scree near the base advises cautious footing. Bring plenty of water and stable footwear to navigate the uneven ground from trailhead to base. Locals recommend double-checking cams before the crux; a confident rack and careful strategy make all the difference.

Choss-o-saurus stands as a gritty introduction to trad climbing in this storied region, marrying technical moves with the charisma of old-school, less polished terrain. It is well suited for climbers wanting to push their nuts-and-bolts skills while soaking up the timeless character of the Alabama Hills. Prepare well, move deliberately, and let the climb challenge both your gear placement and your composure amid the sunbaked granite contours.
