Have any of the animals at the Desert Museum ever escaped?
There have been a few escapes over the years. Probably the most famous was a "beaver breakout" which took place a number of years ago. One night, the beavers left their pond, waddled through the bighorn enclosure and escaped into the desert. The next morning Museum people followed their tracks, which headed west and before long stopped near a set of coyote tracks. Swirling beavertail prints in the sand showed how the beavers had made an about-face and headed back to the safety of their pond. They never attempted another escape.
