The Hole in the Rock
Summary from Rodside America (who do a far better job than I discribing this):
Albert Christensen's home is in a neighborhood of its own -- the knobby, treeless void of southeastern Utah. Not content to be just another guy with a drill and a dream, he hand-carved his luxurious suite of rooms out of a natural cliff face in the 1940s. He called it Hole N' The Rock. It lies on US Highway 191, south of the natural thrills hub town of Moab -- seasonably overrun by hiker hordes, rock climbers, off-roaders, and rafters.
Albert blasted and drilled for 12 years, then moved in with his wife Gladys in 1952. The couple operated a diner in the first room until 1955 (Albert's first heart attack). Albert died in 1957, but Gladys lived 17 more years, running a cafe and gift shop.
Today, the cliff is covered with huge painted white letters that scream out "Hole N' The Rock," letting passersby know there's something here that's wondrously unnatural. A Rushmore-like head of Franklin Roosevelt is carved into an alcove near the entrance.
Inside is a 5,000 square foot home with 14 rooms. Some are interesting simply because of the sheer rock-carving mania they required. A cavernous bathroom is referred to as "a toilet in a tomb."
