Jonathan and Roseann Hanson


Born and raised in southern Arizona, we are both writers, photographers, artists, biologists, and explorers. We are curious humans who love nature, the visual arts, the written word, all things classic—vehicles, bicycles, motorcycles, tools, crafts—and above all, we love to learn.

We are constantly reading, exploring new ideas and crafts and skills. This website is a way to share our passions.

We own and manage Overland Expo, a do-it-yourself adventure travel event, which in part supports ConserVentures.org, our charity which is dedicated to promoting exploration of the world and conservation of its natural and cultural heritage.
We met and married in 1984, and have worked as resident naturalists and caretakers for U.S. Fish and Wildlife at Brown Canyon in Arizona’s Baboquivari Mountains; managed a guest ranch / nature lodge in the Chiricahua Mountains; taught dozens of nature and writing workshops; lead safaris in Kenya and Tanzania; and explored around three continents together. 
In the 1980s and early 1990s we both studied at the University of Arizona, under such renowned field ecologists as Steven Russell, Charles Lowe, E. Lendell Cockrum, Donald Thompson, James H. Brown, Joe MacAuliffe, and others—solidifying our passion for fieldwork and science. 
Our co-authored books include Southern Arizona Nature Almanac Basic Essentials: Animal Tracking, National Park Tours of the Southwest, Desert Dogs, The Ragged Mountain Guide to Outdoor Sports, which won a national book award, and 50 Common Reptiles and Amphibians of the Southwest, which won a National Park Service award for Interpretive Excellence. (For a full bibliography, please see our Portfolio page.)
Ravenrock is our home, located in the middle of nowhere, more or less, 45 miles southwest of Tucson, surrounded by half a million acres of wildlands and ranchlands near the Mexico border. We live off-the-grid, using solar and wind power, satellite and cell phones, and are slowly building a small home from recycled and sustainable materials.
