Continue west up the south side of Forster Creek staying in the centre of the long valley aiming for waterfalls coming down a rock headwall near the end of the valley. Bushwhack up 60m to alpine meadows north of the headwall. Follow the terrain for 1.5kms heading west up to the south end of the lake.
The lakes are a great place to explore.

Things to do?
1. McLean Lake trail from Frances Creek (one creek north) gives access to McLean Pass at 2440m (8000’). Great views of Thunderwater Lake and Catamount Glacier from across the valley.
2. Most of the rock here is rotten and poor climbing. But immediately west of both lakes between False Forster and Forster Passes, is a long ridge of granite. One of the more special places is a small tarn (285-108), often ice-bound until well into August, at the east end of the ridge. Explore down this ridge.
3. Hike up to Edouard Pass. In August 2017, the Kootenay Mountaineering Club held their hiking camp at the pass over 3 weeks. The above tarn was a favourite destination. A good game trail climbs up to the lake on the pass. Climb “Pulpit Rock” immediately to the west of the lake. This would be a long day hike from Thunderwater Lake.
4. Go to the Olive Hut (82K/10 313-088, on a NW ridge off the Scotch Peaks) . Because of glacial receding, it should be possible to avoid walking on the Catamount Glacier.

About admin

I would like to think of myself as a full time traveler. I have been retired since 2006 and in that time have traveled every winter for four to seven months. The months that I am "home", are often also spent on the road, hiking or kayaking. I hope to present a website that describes my travel along with my hiking and sea kayaking experiences.
