The shores of Lake Sacajawea in eastern Washington are dominated by 600-foot-high Palouse Hills, clearly indicative of the effects the Missoula Floods had upon the landscape 13,000-15,000 years ago. The 32-mile-long lake was formed by the construction of Ice Harbor Dam on the Snake River east of Burbank in the 1950s. Slipping through this incredible landscape late on a glorious autumn afternoon is a southbound UP potash train with a quartet -- split into two pairs -- of SD9043MACs in charge, ultimately destined for the bulk export facility at the Port of Portland's Terminal 5.
