I have found 4 separate dens in cliff faces here as well. Seems like anyplace with enough room for them to get into and away from man; usually(not always) south facing, are used at some time or another, depending on availability. Here, everything has holes in, under, or around it. Just when you THINK you have patterned their denning behavior? you will find one smack dab in the middloe of a desert flat or grain field. Helps perpetuate the species. Had one that used a field drain culvert, 10 feet down in a drain, in the middle of farm land, that was dry and usable. We never thoght of looking out there until the pups started vocalizing. Go figure...................................
