Lava River Caves and Crater Lake Flagstaff Hiking
Flagstaff Lava River Caves: A Subway into Time
The "Tubes", better known as the Lava River Caves in the San Francisco volcanic field north of Flagstaff, are unique, wondrous, and geologically fascinating.  We will explore the length and breadth of these caves, as well as a pleasant lake in the center of an extinct volcano, while observing the volcanic activity that has been important in shaping Flagstaff and northern Arizona over the past several million years.
