AMGA Apprentice Rock Guide
AMGA SPI
Avalanche Level Pro 1

Hailing from the pastel colored plains of Central Kansas, Stephen Larson grew up driving tractors and chasing cattle. When his job title transitioned to “professional mountain biker” a new love was found; the endless call for adventure. Stephen now spends his time as an avid outdoor athlete, guide, and ski patroller, pursuing a career as an IFMGA Mountain Guide. Fortunate enough to split time between the Range of Light, the Adirondacks, and the Volcanoes of the Pacific Northwest, Stephen has developed the ability to morph between climates, cultures, and cooking styles. As a storyteller, he strives to inspire through words and pictures that derive from his love for sharing the warmth of the first rays of sun high on a mountain, hours after waking up and thinking “is this really worth a 12am start.”

But always finds his way back home to the Sierra Nevada where he spends most of his time.
