There are quite a number of interesting things to do and see around Flagstaff. Some that come quickly to mind are Sedona and Oak Creek Canyon, Wupatki Natl Mon, Sunset Crater Natl Mon, Walnut Canyon, the Arizona Snow Bowl at the San Francisco Peaks (main attraction in summer is a chair lift ride to the top of the ski slopes where a dizzying view encompassing 5 states can be had on a clear day). All of these are within 25 miles of Flagstaff. Wupatki and Walnut Canyon are ruins of native peoples' habitations, abandoned around 700 years ago. In Flagstaff itself, one can visit and tour the Lowell observatory which still houses the telescope used by Percival Lowell to study Mars (he believed there was life on Mars because he thought he could see "canals" on its surface) and equipment used to discover the planet Pluto (a device called a blink comparator) -- it still has the Pluto film plates in it and you can see exactly how Clyde Tombaugh (janitor and astonomer!) discovered what everyone else had missed for YEARS (to make a long story short, the orbits of the other planets near Pluto provided indisputable mathematical evidence that Pluto was THERE, but no one could find it)! I also recommend a visit to the Riordan Mansion -- a log home built back around 1900 that housed two lumbermens' families in two wings, with a "great room" connecting. The home is now a state park and rangers guide tours through the home (in Flagstaff). Be sure they show you how the "air conditioning system" worked. On Highway 180 in the north end of town, there is a good museum (I think it is called the "Museum of Natural History"). Within 50 miles of Flag, you could also visit Jerome (an old mining town now artist colony), Montezuma's Castle and Tuzigoot Natl Mon (two more Indian ruins), and Meteor Crater (near Winslow). If you take the eastern route to the Grand Canyon, via US89, you could also stop at the Cameron Trading Post. It's a tourist trap, but the food is decent and the building and trading post are original and authentic (and still in operation); they're worth a look. AND, at the junction of US180 and AZ64, the Planes of Fame Museum (of Chino, CA) has a satellite museum that houses some wonderful old aircraft, including the Lockheed Constellation that served as Gen. Douglas McArthur's transport when he flew to Guam to be fired by President Truman! Is that enough? Have a good trip! Here's an extra credit trivia question... can anyone tell us how the Grand Canyon got its name? The answer is simple, but maybe not what you'd think!
