1.5 hr
From the bottom of the hill take this wide, twisting, dirt fire road uphill and after 1.5 miles, stay right at the first split, a sharp, uphill switchback, and keep climbing. In less than a mile, look for a split to the left, Miller Lateral. This will take you to Middle Switchbacks and Washout in Marshall Canyon. If you go right it will take you back to the low swinging gate and Cobal Canyon - La Verne.
