AZ Illustrated Nature visits Tumacacori National Historial Park park south of Tucson, known for its historical, cultural and environmental attractions in the area. This is followed by a look at the three National Parks within the state’s boundaries. Next, we talk to different groups that are "friends" of national parks by providing volunteers and donations. And, we report on the second annual Santa Cruz Nature and Heritage Festival, which includes cultural classes, birding tours, history lessons and other activities.
