I spent some time camping at several of our national parks this past summer. Arches National Park is in eastern Utah. I did a lot of hiking and saw many of the 2,000 natural stone arches, in addition to sky-high peaks and giant balanced rocks. One evening, a ranger talked about the kinds of wildlife that live in the parks. Desert bighorn sheep and mule deer can be seen often, but mountain lions come out at night. Kangaroo rats, lizards, spadefoot toads and many types of birds also live in the park. Take pictures when it is safe, but don’t bother the wildlife, the ranger said. Purrs, Gulliver
