Here is a "Topo/Image Map", with approx. route we took. Hike up a deactivated logging road. 100m before the roads end head north hike slash for a short distance then up steep timber for 300m to gain the ridge top. Head east over to a small tarn and then up to the base of a dark cliff hike east around the base before climbing up a wide gulley to reach the meadows above the cliff. Once on top there is a couple of small tarns and from here you can choose various ways to reach the summit. With the snow conditions at the time we were able to climb straight across the meadows and up North face without any difficulties or avalanche dangers

I hope that you enjoyed viewing the Image Map of the Route Up Mnt Adder Cheers: Quagger
