History Expeditions will present The Fremont Sierra Expedition 2026. The event covers the five day, 100 mile mountain journey that honors John C. Frémont’s audacious 1844 winter crossing of the Sierra Nevada. Also covered will be the deep connection to the Donner region and westward expansion.

The team of five veteran endurance athletes and researchers will retrace his documented route. The route runs from Bridgeport through Charity Valley, Red Lake Peak, Carson Pass, and down the South Fork of the American River to Strawberry. This ties year of historical research to boots on the ground field verification.

In 1844, Frémont, guided by Kit Carson and others, rejected Chief Truckee’s recommended Truckee River–Donner Pass corridor. They instead forced a desperate mid winter line over Carson Pass, enduring deep snow, starvation, and psychological strain.  But they lost no men—a striking contrast to the Donner Party’s tragedy two years later.

Their mission is to stand in that same high country to understand his decisions better. Along with investigating unresolved mysteries such as the missing howitzer barrel and possible scientific instrument caches. And, to document Indigenous guides’ roles, and use GPS, film, and daily journals to create a fully digitized, field verified route map. Add to that rich storytelling that allows visitors and the public to experience this survival epic and its legacy with us.
