Rio Sonora
The Rio Sonora runs through the hill country of the north central part of the Mexcan state of Sonora draining into the Sea of Cortez. It is a remote region that is mostly arid, covered with mesquite, oaks, valleys of cottonwoods and sycamores, and cactus. I visited for several days in late September 2020. It's a low populated and rarely visited region where visiting feels like traveling back in time.
