 Then in the late 1920s and 1930s, Thorp experienced a remarkable economic boost despite the Great Depression that had descended upon the nation.This period of growth and prosperity was led by an influx of timber workers from the Taneum Canyon, where the Cascade Logging Company maintained a portable logging camp.In 1928, Thorp became one of the headquarters for the Bureau of Reclamation's Kittitas Division of the Yakima Project which focused on construction of the Highline Canal, an event that brought yet more activity to the town.
