Alpine Rock
701 routes and 368 boulder problems at 124 crags. "Alpine Rock" is the catalogue's own grouping — a town, a canyon or a corridor, whichever climbers actually say.
Which way a wall faces is known for 77 of these 124; the rest say nothing rather than guess. Sun and shade by season ranks the ones we know.
At a glance
- Crags sit between 8,516 and 14,330 ft (elevation known for 124 of 124).
- Rock, where known (115 of 124 crags): granite (76), gneiss, schist & quartzite (28), sandstone (9), basalt & volcanic (2).
- Mapped geology under these crags (123 of 124 read off the geologic map): biotite schist (24), biotitic gneiss, schist, and migmatite (15), silver plume granite (13) and 28 more units.
- The USGS has mapped this ground since 1889; each crag page shows its oldest sheet.
- No crag here is within 1.5 km of an RTD stop. Mapped toilets within 2 km of 28.
