Mt. Lemmon Highway (red line): One of America's best single-day natural history tours, the Mt. Lemmon Highway traverses 6500 feet (2000 m) of elevation with very little driving. Stops will be made to see multiple different forest ecosystem types. Dendrochronology projects will be visited, and wildland fire management will be featured.

Our tour of the UA Biosphere 2 will include going inside. Then, Catalina State Park has the Romero Ruin, a classic period Hohokam surface pueblo, and a bosque of mesquite, one of the more important tree species of the Sonoran desert. Owls are possible at dusk.

San Xavier Mission and Madrean Woodland (green line): The San Xavier Mission is a prime example of Spanish Mission architecture, and it serves as a focal point for discussion of the Spanish Entrada into the American Southwest. Then, the Santa Rita Experiment Station, the oldest experiment station in the US, has an extensive history of environmental research. Lastly, Madera Canyon is a popular respite from the heat and a classic Madrean Mixed Woodland, complete with active bird feeders and perhaps owls at dusk.
