Salt River

The Salt River is Arizona’s whitewater river — the only significant multi-day canyon run in a state better known for its role in the Colorado River system. The Salt rises from the confluence of the Black and White Rivers on the Fort Apache Reservation and flows west through a deep, rugged desert canyon in the Tonto National Forest before reaching Roosevelt Lake. The upper Salt River canyon above the reservoir is a Sonoran Desert whitewater experience unlike anything else in the Southwest: saguaro cacti on the canyon walls, Class II-IV rapids fed by winter rain and spring snowmelt from the White Mountains, and a sense of remoteness that belies the river’s proximity to Phoenix. The Salt runs only when the White Mountains deliver enough water — typically winter through early spring — and in many years the window is narrow. Below the chain of dams (Roosevelt, Horse Mesa, Mormon Flat, Stewart Mountain), the lower Salt through the Phoenix metro is a completely different river — a tubing and recreation corridor fed by dam releases. The upper canyon is the section that matters for boaters: wild, intermittent, and distinctly Arizonan.

The Salt River canyon cuts through the Transition Zone between the Colorado Plateau to the north and the Basin and Range Province to the south. The canyon exposes Proterozoic-age Pinal Schist and Apache Group quartzite — some of the oldest rocks in Arizona — intruded by Tertiary volcanic flows. The resulting geology creates a narrow, rugged canyon with hard-rock rapids and steep walls.

The upper Salt River canyon supports a winter bald eagle population — one of the southernmost regular concentrations in the continental US. Saguaro cacti on the canyon walls give the river its distinctive Sonoran Desert character. The riparian corridor through the canyon is an ecological oasis in otherwise arid terrain.
