Visitors to Yellowstone National Park’s Canyon Village, the largest accommodation complex in the park, were pleasantly surprised last summer with brand-new accommodations. The stately, welcoming new lodges were the result of a two-phase, three-year transformation of the 410 obsolete cabin-style units, originally constructed in 1957, into five modern, multistory stone and wood structures (with an equal number of units) built in the grand lodge tradition of the National Park Service.
