About two years ago I found an old, abandoned cattle trough that still held water. I realize now that it is an old spring box that still receives water from a nearby spring. The good thing is, it stays full of water during the Arizona dry season (between the winter rains and summer monsoons) and so is an important water source for local wildlife during times of water scarcity. For bears, water is not just a resource to drink, but also to wallow in and relax:
