The nearly century-old Grand Canyon Lodge in far northern Arizona was a refuge for ambitious hikers and adventurous tourists eager to bask in the magnificent views of one of the most remote and renowned landscapes in the world. “It's tragic, it really is,” retired National Park Service chief historian Robert K. Sutton said Monday. Gilbert Stanley Underwood, who designed the lodge in 1927, sought to immerse residents in the landscape that now draws millions of visitors annually from around the world with a rustic, organic architectural style.
