Petrified Turd stands as a short but memorable route tucked into The Grocery Store Walls, just within the boundaries of Castlewood Canyon State Park near Denver South, Colorado. This single-pitch trad climb draws attention more for its unusual character than for any classic appeal. The line follows a wide crack ranging from two to four inches, but what truly marks this climb is its distinctive guano-filled crack, adding a layer of challenge unlike most climbs in the area. The rock feels firm, but the presence of guano transforms the route into a sticky and decidedly uninviting experience.

Approach this climb with a sense of pragmatism. The trail to the Grocery Store Walls is straightforward, set within the rugged landscape of Castlewood Canyon with scrub brush and rocky outcrops framing the arrival. The walls catch the afternoon sun, casting light that reveals the textured surfaces and paints shadows into the crevices. The area is open and exposed, inviting a breeze that can help offset the heat on warmer days but offers no respite from the smell that accompanies the guano.

The crack itself demands protection in the form of traditional gear from 2 to 4 inches—cams and large nuts slot in solidly, offering a reassuring hold on an otherwise awkward climb. While the rock quality remains good, the environmental conditions require an honest appraisal: this climb is more a curiosity than a classic line, better suited to climbers looking to tick off a unique pitch or gain experience with wide crack placements under unusual circumstances.

Timing your visit to Castlewood Canyon for cooler parts of the day will ease the discomfort of both temperature and odor. Consider exploring nearby routes like Hot Fudge to find more inviting rock and engaging movement if Petrified Turd’s distinctive conditions prove unappealing. Whether you're chasing a brief crack line or simply marking off a lesser-known climb in the Denver South region, this route offers a straightforward but decidedly memorable climb—and a reminder that not every route is destined to be a favorite. Practical gear, clear expectations, and a spirit of adventure are your best companions here.
