Los Alamos Canyon 

I'm quite surprised to see this information here. I'm not much of an ice climber but I thought certain local ice climbers really tried to keep the local town stashes quiet for fear that the limited ice would be beat-out and destroyed.

There are also tons of sport routes in this area, though most are of lower quality and are missing their hangers. FAs mostly by Shibli Fazal in the mid-90s. If you do a little looking, you can find them, but I don't have the info anymore (at least that I can find) so you'll have to explore.

The majority of the routes are about one third of the way up to the reservoir on the right.
