SMARR--Tucson Wash Trestle
San Manuel Arizona GP38-2 16 crosses Tucson Wash at Mammoth, Arizona, on March 18, 2004. The train is en route south from Hayden to the smelter at San Manuel, just northeast of Tucson. The smelter has since closed and been dismantled. The SMA seldom runs these days. Photo by Joe McMillan, used with permission.
