17 Room Ruin

Just outside Bluff on the canyon walls above the San Juan River, a well-preserved Ancestral Puebloan ruin of around 17 rooms is tucked beneath a desert cliff. The site dates from the Pueblo II–III period (900–1300 CE) and retains several walls standing to roof height, with intact niches, doorways, and the remains of a kiva visible in the structure.

The ruin is accessible without a permit and can be reached by a short walk from the road. It serves as a good introduction to the canyon archaeology of the region before tackling the more remote sites of Cedar Mesa and Grand Gulch. Signs in the area ask visitors not to touch or climb on the walls — the adobe mortar is fragile and has no legal protection once damaged.

A story
The ruin was occupied during the Pueblo II and Pueblo III periods, roughly 900–1300 CE, before the Ancestral Puebloans abandoned this part of the Colorado Plateau in a migration that remains one of the great unresolved questions of Southwest archaeology. The site sits on land near the road, but its well-preserved walls — still standing several courses high in places — make it one of the most intact surface ruins accessible without a backcountry permit in the region.
