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.
