Visitation and Usage
Popular tourist and hiking destinations in the volcanic field include the Kendrick Mountain Wilderness, 20 miles northwest of Flagstaff; and Sunset Crater, which is particularly popular because it is easily accessible and has interesting horizontal lava flows at the base of the crater.
Areas of the volcanic field have been used by NASA for testing techniques for exploration in a simulated extraterrestrial terrain environment. NASA has also conducted the Desert Research and Technology Studies (DRATS) tests here.

Famous quotes containing the word usage:
“Pythagoras, Locke, Socratesbut pages
Might be filled up, as vainly as before,
With the sad usage of all sorts of sages,
Who in his life-time, each was deemed a bore!
The loftiest minds outrun their tardy ages.”
—George Gordon Noel Byron (17881824)
