Lat: 61º 06.568' North
Long: 149º 33.878' West

Access: From the Glenn Alps Trailhead access the Powerline Trail.  Hike or ski the trail (going away from Anchorage) until one comes to obvious trailhead on the left hand side.  Hike/ski the trail down and over the creek then choose to either hike/ski to the 'football' field or go around via the Williwaw Creek Trail.  Either way, hike/ski until you get to the north side of O'Malley Peak.  O'Malley Waterfall is the obvious falls located above the Williwaw Lakes on the north side of O'Malley.

Route: Mostly moderate ice the entire way with a couple short curtains of WI3. 

Anchor: Alders are sparse so bring v-thread material.
