Blackerby Ridge is located in the Lemon Creek Valley above Twin Lakes. Access is easy. Drive up behind Twin Lakes to Wire Street and park at the end of the street in the empty lot. Pack your bags and head up your favorite drainage or access the Blackerby Ridge trail head. The main first drainage on the left is where you will find Knucklebuster, the largest climb on the ridge. Other good routes include the sought after The Fang.
