little joe, My email has been messed up lately. I recently got DSL and my old email address is difficult for me to read. I have also setup my web site to handle email and it appears to be working now.
I have seen marmonts in some of the high mountains. They appear to like elevations above 9,000 ft. There are a few near Moniter Pass and there are some 4WD roads into the area. Surprisingly, there are even some of the large CA ground squirrels there too, but not too many.
When we used to go backpacking, we would see marmonts at the high lakes, all the way up to 12,000 ft. This was down near Mt Whitney, but that was in a park.
Thats about all I know about the rock chucks or marmonts. Loads of ground squirrels in Central CA, though. But, you have to get access because most of them are on private land.
