The one in the picture is the California ground squirrel. They range fron California to Washington. They are thick around The Dalls. Around here they are found everywhere but our favorite place to hunt them is in the mature clear cuts. They burrow under root wads and under slash piles and in rocky places. The clear cuts age is important. The grass must be well esablished and the replanted trees not over 2 to 4 feet tall. Taller than that and you can't see them out sunning themselves.
A mature male can get up to 3 pounds or so. It takes a big gun to get some air time on them past 300 yards. You have to hold just under center of the gut sack for max expansion.
