Hello,
I've created a map of the Sierra Nevada, focused on the SPS peaks, that might be of interest and value to members of this board. I've been working on it in my spare time for about a year and, while I don't feel like the map is finished, I'm eager to get some feedback from its intended audience.
I've used printed versions of my map side-by-side with USGS topos on some trips and while I'm not ready to say that they are better, I think they can be a good resource for the backcountry peakbagger.

Thanks,
Dan
