Above the new reroute lies the what's left of "old" Corbly. Raw and primitive makes this trail an adventure no matter the direction ridden/pushed. Trail alternates between steep creek bed, open meadows and forested slopes eventually popping out in the alpine where a series of well graded switchbacks (the most reasonable part of the trail) lead you to the saddle just north of Sacagawea and the intersection with the Foothills trail.
