Rio Aros

Twelve Days From the Rio Tutuaca

Confluence of Rio Tutuaca and Sirupa, begin Rio Aros

By Huck

Recently I had the opportunity to see, by raft, the country I've been tramping overland for the last couple of decades. Just getting to the put-in of our trip was a logistical conundrum and an exercise in patience. We needed a shuttle driver who was comfortable in the fringe area of Copper Canyon, Chihuahua, and the driver might have to spend two, maybe three nights on the road before getting home. Then he would have to pick us up in 10 or 11 or 12 days; and who knew for sure. This trip is best attempted when the water has a good flow, but unbeknownst to us, a tropical hurricane (Norbert) was heading for the sierras preparing to drop 3 days of solid rain in the drainages that fed our rivers. We recently had some decent enough flows from summer monsoons after a prolonged dry spell to even attempt this project. As it turned out, it rained all night and part of the second day as we headed deeper into Chihuahua from the take-out point near Sahuaripa, Sonora. The side canyons in the cordillera of the sierras were roaring with brown water--not a good sign. The next day we contemplated a delay, but a promising sucker hole of robin egg blue sky beckoned us further as we polished off breakfast of strong coffee, papaya and granola bars. We left the highway on a broad sinuous dirt road for the last 100 kilometers, a four hour drive to a rickety logging bridge halfway between Yepachic and Madera. (Photo gallery from trip)

Rios en El Bronco - Rivers in Rough Country

Rios en el Bronco, Rivers in Rough CountryHere's an article in Terra Magazine (put out by ConserVentures) literally about Wild Sonora. Read about adventures on the rivers of eastern Sonora and see plenty of photos of the most recent trip.

"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.
