The name Thunderwater conjures up images not just of water but of churning, splashing, falling water. This hike features an abundance of moving water, frozen water, scenic tumbling cascades, icy creek crossings and damp meadows. Fording creeks is typical of remote alpine hiking, but this hike crosses glacial creeks with fast current and fluctuating, melting-ice runoff.
Thunderwater Lake is an amazing, high-elevation, turquoise, alpine lake stretching out in a 2-km-long, glacier-hewn, oval valley at the headwaters of Forster Creek. Thunderwater and Whirlpool lakes both tuck below the flanks of Catamount Glacier.
Thunderwater Lake is the largest lake in the vicinity, and along its northern shore sparkling springs trickle between grassy mounds, where brightly coloured wildflowers spread over the moist slopes. The landscape is vibrant with colour for just a couple of weeks in early August.
Only 60 m (200 ft.) higher than Thunderwater Lake hides indigo-coloured Whirlpool Lake. Larch trees and slopes of wildflowers are sparse along its bleak shores.

Trail
0 km: Parking at the end of Forster Creek Road, N11630-E34851, at 1670 m (5,500 ft.). Cross the light-blue Forster Creek on a well-built bridge. Follow the remnants of an old road west, parallel to the creek. The trail is well-used by snow machines, so it’s in fairly good shape.
600 m: Cut-off trail rips off a road switchback, saving only about 200 m.
1.2 km: Windermere Valley Snowmobile Society cabin built in 2000, called Forster Cabin.
1.9 km: Cross creek twice within 50 m.
2.4 km: Trail ends. Hug the south (left) side of the wet meadows, following bits of trail through semi-open forest.
2.8 km: Large, white moraine. For Thunderwater Lake stay at the same elevation and cross over the mound of the moraine. Sketchy flagging and some cairns mark the way. About halfway across the moraine, the defined trail for Olive Hut and Catamount Glacier, N11732-E32482, branches left (south) and ascends the rocky moraine (with the steeply bouncing Scotch Creek on your right).
3 km: Large Scotch Creek. Wade in the shallows near the confluence with Forster Creek. Stay south of Forster Creek and hike near the centre[…]”
