3mm rain forecastDo not climb wet desert sandstone — holds break and cams pull
  • Do not climb — wet desert sandstone is severely weakened, cams can pull and holds break, permanently damaging the route
  • Good friction temperature range for desert sandstone
  • Elevated humidity for a desert crag — subsurface drying will be slower than expected

About Sister Superior

Sister Superior is the tallest and most popular of the Sister Superior Group — a set of Wingate towers on the ridge extending northeast from Castleton, ~4km up-valley from the Castleton/Rectory/Priest cluster. Thin-tower summit reached via 300+ft Wingate walls on a Moenkopi-Chinle base. Same 48h wet-Wingate rule. Own weather anchor (not grouped with Castleton) because the ridge separates it from Castle Valley proper.
