My photos of the 2011 Western States 100 Mile Endurance Run were taken at the Duncan Canyon aid station and checkpoint. The course had to be modified for this year’s event due to snow drifts as deep as 8-ft in the high-country of the Sierra Nevada Mountains (yes, in late JUNE!). In 2011, the Duncan Canyon Aid Station (elev. 6,090 feet) was the fourth checkpoint after the start in Squaw Valley. It was relocated from its usual position to a point where the Western States Trail crosses Mosquito Ridge Road near French Meadows Reservoir.
