Learn more about the host city, Flagstaff.
Flagstaff is a city of over 75,000 people (2019) near the San Francisco Peaks mountain range of northern Arizona and the Grand Canyon. At an altitude of 6,990 ft (2,130 m), Flagstaff and much of the surrounding region are substantially cooler than the low desert that dominates the southern part of the state. Though still dry by east coast standards, enough rain and snow falls in the area to allow a forest of ponderosa pine trees to cover the landscape. Winters tend to be cold, and heavy snowfall is expected on an annual basis.
