Wyoming Expeditions. Gallery Roach is named for the late Otto Roach, a prominent commercial photographer in mid-twentieth century Denver. His lab, Roach Photography, earned a fine reputation for photo finishing. Dutch Walla, who became Roach's associate more than fifty years ago, now owns both the gallery and the lab. Wyoming Expeditions features Roach's photos of Wyoming from the 1940s through the 1960s. They're done in black and white, with Roach capturing many famous scenes, including such remarkable Yellowstone National Park subjects as the surrealistic Jupiter Terrace and the majestic falls at Yellowstone's Grand Canyon. Roach repeatedly visited nearby Wyoming to take photos, so he was able to supplement the well-known Yellowstone attractions with shots of unknown backcountry views. Surely the standout is a gigantic mural measuring seven feet by ten feet. And if the tremendous size of the photomural were not enough of an accomplishment, the entire thing has been hand-tinted!
