Question
I live in Las Vegas, an arid area. While pulling weed from my desert landscape, i noticed a hole that had been dug descending downwards with the dirt from the hole piled outside. I am concerned about what it could be and what to do about it. There is a hole on one side and another one next to it which seems like an entrance and an exit.

Answer
Tough to be certain without more information such as size of hole.  But I would think a ground squirrel. http://www.icwdm.org/handbook/rodents/FranklinSquirrels.asp

Photos are welcome, use highest resolution, and a ruler in picture for scale.
