Hannah Lily Hall is an athlete based out of Mammoth Lakes, California. If she isn't scaling a cliff, you can find her running among the mountains of the High Sierras. She will spend this winter working for Hill Safety, a feeder program for Ski Patrol. When - and if - you catch her sitting down, she writes outdoor adventure content on her blog, www.lilynfoxonarock.com . A catalogue of her photos and adventures can be found on her Instagram, Hannahlily17.
