Driving west on County Road 324, from Clark Canyon Reservoir, roughly follows Lewis's route to Lemhi Pass. The Lehmi Pass gravel road cuts west from 324 about 10 mi. past Grant MT. Top left, Trail Creek, issuing from the mountains near the pass. Hugh McNeal straddled this creek farther up and exulted that he could finally bestride the mighty Missouri.
