I remember the discussion about ice skating alpine lakes so I thought this would fit into an odd idea also.
Since taking pictures is one of my favorite things to do in the sierras the idea of taking pictures not of lakes but in the lakes occurred to me...
So you get one of those under water cases for your camera and go for a swim!

Considering that clean clear water you may be able to get cool pictures and if the wind is not blowing you could try to get pictures of the surrounded mountains from in the lake.
A crazy idea maybe but if I actually did it would I be the first?
