Common questions
- When is the best time to climb in the Mountain West?
- June through September, once the snow has melted off the high country. That summer-to-early-fall window is when alpine rock and high-elevation crags come into season.
- How do you deal with afternoon thunderstorms in the high country?
- Start early and aim to be off the summit by noon. Afternoon thunderstorms are common in the mountains, so an alpine start keeps you ahead of the weather.
- Can you climb the Mountain West in winter?
- High-country rock is snowbound in winter, so the season shifts to ice and mixed climbing instead.
