Mammoth Lakes – California – by Nigel Calaghan

Mammoth is a good base to explore the crags on the eastern side of the High Sierra. There are the granite crags such as Dike Wall and crystal crags around mammoth Lakes area. Slightly further south is Rock Creek valley which contains more granite crags including the sub alpine crag of Patricia Bowl. Further south is the bouldering honeypot of Bishop and the nearby Buttermilks. East of mammoth is the high scrubby valley of the Owens River which host some great venues the most famous being Owens river Gorge but there are some other interesting crags such as the volcanic rock of Clarks Canyon

When to climb, Weather and Seasons

This is the dry side of the mountains so usually dry. The altitude is extremely variable from low Owen River gorge ( too hot to climb when we were there in August early Sept) to the sub alpine Patricia bowl. This means you should be able to find somewhere to climb depending on ambient temperatures
