Well, made it back from the White Goat. Fantastic trip, my friend is the official photographer, so no pictures with this report.
Cataract Pass is a beautiful spot, and would be quite doable as a long day hike over Nigel Pass.
We took your advice, Hank, and camped for 2 days below the pass at 2300m and day hiked Cline Pass and exploring over the pass into the Valley of the Lakes, a tough, but safe scree and rock scramble with no exposure. The valley of the Lakes was far starker than I imagined!
There is no trail for a couple of kilometres downstream on the Cataract before picking up surprisingly good track along Cataract Creek. This valley is notable for having the most grizzly activity of anywhere I have seen in Alberta. The subalpine diggings covered huge areas, and there was lots of fresh poop, but with our large party, we did not see any bears. There are lots of downed trees on the trail, but nothing unmanageable.
Rains picked up before Pinto Lake, and we had a cold and windy night before hiking out over Sunset. Didn't see another soul after the Nigel Pass and before arriving at the Lake.
Brad - great website. I hiked the high route over Owen Creek a couple of years ago in glorious weather. I guess the secret is out now - but in my humble opinion its the best single weekend hike in Alberta, and all on provincial lands the Alberta Government deems unworthy of protection.
Back home and already planning next year's Bighorn/Whitegoat adventure.
