Yosemite, one of our most spectacular National Parks, is home to six species of Chipmunks. Each is found at a different altitude, from dry foothills to 13,000-foot peaks. The life stories of several of these frisky, appealing creatures, and their relationship to humans, are seen amid the grandeur of Bridal Veil Falls, Half Dome and the world's oldest and largest Giant Sequoias.
