On this tour, we visit the Buenos Aires National Wildlife Refuge, which has breeding programs for the endangered pronghorn and Masked Bobwhite Quail and offers birding for many species including Herons, Gray Hawks, Vermillion Fly Catchers, Loggerhead Shrikes and Golden Eagles. We will take in a lot of local history, learning about the Spanish Barb horses that descend from Fr. Kino’s herd, about the Mexican Revolution as it was played out here, and about old ghost towns and mining camps. We take a side trip to see the border town of Sasabe, sprinkle geology lessons in, have a morning free for optional activities such as riding e-bikes or horses, and enjoy fabulous meals. Come nighttime, we are treated to cowboy poetry and a star-studded winter sky. |
Black Lava White Sand
December 15 – 18, 2024  | Explore El Pinacate y Gran Desierto de Altar Biosphere Reserve, a UNESCO World Heritage site, with cultural conservationist Jesús García and geomorphologist/anthropologist Fred Nials. The volcanic landscape of the Pinacates includes huge maar craters, two varieties of lava flows, cinder cones, and majestic shifting dunes hosting their own specialized ecosystems. This young volcanic field is adjacent to the Sea of Cortez, which because of extreme low tides allows viewing of its marvelous intertidal marine life at the Center for the Study of Deserts and Oceans. Uniting the desert and beach is one of the most important natural salt reserves in Mexico, Campo La Salina. Located in Gulfo de Santa Clara where natural freshwater springs and saltwater meet, this layer of salt is sacred to the Tohono O’odham. For a special cultural experience, we’ll visit the O'odham community of Quitovac, an important oasis along the ancient salt pilgrimage trail to the sea.
