Approach via Herman Lake Trail and continue up the drainage when the trail turns right up a hill (north). Gain the ridge line to your left (south) and continue up to a nice, flat spot (balcony) before the rocky, more difficult, summit.
A fun line in the alpine environment off the east ridge line of the Citadel AKA "Snoopy - Tail". This line starts only 100-150 feet vertically below the top of the notch on the Citadel. It gets sun so you can harvest some corn earlier in the morning.
