Perched at an airy 8,041 feet, the Sphinx Sector offers a unique slice of Ten Sleep Canyon that draws curiosity and challenge with its distinct outcropping of stone. Unlike the more continuous walls nearby, the Sphinx Sector presents a break—a literal gap in the canyon before the formation emerges again, inviting climbers into its quiet domain. This character of separation carves out its own mood: less traveled, more contemplative, and ready for adventure.

Approaching from lower in the canyon, the path leads past the notorious Superratic wall before the main cliff line vanishes for about 25 yards. What lies beyond is the Sphinx Sector—a cluster of routes that make the most of this distinctive chunk of rock. Framed by the classic Wyoming high country, climbers are met with pine-edged vistas and the subtle hush that comes with climbing at elevation, where wind and birdsong often replace crowds and chatter.

Climbing here is all about variety across a spectrum of difficulty, from approachable 5.10s through to the athletic rigors of the 5.13s. Enthusiasts of solid movement will want to get on Egyptian Rat Screw (5.10d), a favorite that balances technical demands and rewarding flow. The local standout, Hot Milk (5.11c), earns high marks for its entertaining sequences, often described as a satisfying test piece for those breaking into the grade. If you’re ready to turn up the intensity, Good Luck Jonathan (5.12b) and Rude Cowboys (5.13a) stand ready with steep challenges and thoughtful climbing, each offering something new to those seeking to push their limits.

Navigating Sphinx Sector’s terrain, you’re treated to the unmistakable feel of high-elevation limestone that Wyoming is known for. The air is cooler, the rock solid, and while the sector isn’t sprawling, it packs quality into its short stretch—an ideal focus for a half-day mission or a targeted stop along a tour of the canyon. On good days, sunbeams cut through the crisp mountain atmosphere, illuminating sculpted lines and offering comfortable conditions, especially during the height of summer.

Access and environmental stewardship go hand in hand here. Climbers should stay aware of ongoing raptor closures and route development restrictions: due to monitored nesting in the greater area, portions of the canyon are closed seasonally and new routes are on hold per Forest Service guidelines. It’s all part of a collective effort with the local climbing coalition and the Forest Service to keep the environment, and the climbing experience, sustainable for years to come.

The sector offers easy navigation, clean approaches, and straightforward descents; but, as always in the Wyoming high country, check weather before you go—conditions can shift rapidly at this elevation. With a bit of planning and respect for local guidelines, a day at the Sphinx Sector becomes more than just another outing; it feels like your own pocket of the canyon, a place where climbing is a focused, personal pursuit, surrounded by wild landscape and big Wyoming sky.
