Rios en El Bronco - Rivers in Rough Country

Our adventures into the river canyons of eastern Sonora began in the early 2000s after spending several years working throughout the bronco (rough) state of Sonora, México. My best friend was an avian biologist working in Sonora, and I had always been intrigued by birds, natural history, and landscape exploration.

Our trips were driven by biological interest, deeply embedded wilderness exploration genes, and our desire to fill information gaps about the Sonoran countryside and its biota.

La Morita rapid on the Rio Aros, Dec. and July comparison

Photo comparison of La Morita rapid on the Rio Aros in both December 2011 and July 2012. December flows were high for the time of year and July flows were near average.

Flows in late spring and early summer are so low that the run in the foreground is completely non-existant (dry). What flow there is on the other side of the river moves between and mostly under the house-sized boulders.
