Bad weather comes up quickly in Glacier due to the mountain ranges and the varying temperatures. Here is some rain clouds coming in over the ridge with a nice set of waterfall steps coming down the gorge.
Avalanche Lake feed into Avalanche Creek/Gorge. The lake is fed by at least 5 waterfalls, some seen coming over the ridge of the bowl. The logs are jammed up at the exit point of the lake - most likely here for quite some time.
