The sandstone outcrops at Roche Percee in Saskatchewan are a protected heritage site, named by an explorer who came through this area. The carvings made by wind, water, heat and cold have been augmented by more recent two-legged visitors, despite a no graffiti rule.

Sculpted by wind and water, the sandstone at Roche Percee displays holes in the formations, which led to the locality being named Roche Percee.

Roche Percee received its name from an early explorer who was impressed by how wind and water erosion had carved out holes in the sandstone in the area. This is one example.
