New Field Guide Explores Geology of Flagstaff and Rio de Flag

"This geology and trail guide is for anyone who likes to walk, be outdoors, and is interested in the geology in and around Flagstaff."  – Richard F. Holm

With summer approaching, the latest in our Down-to-Earth geologic and trail guide series might inspire those living at lower elevations and higher daytime temperatures to visit the cooler days and nights of Flagstaff, Arizona.

This new booklet recounts the geology of Flagstaff, Arizona, with emphasis on the history of the Rio de Flag drainage that runs through the town. Part 1 includes a synoptic overview of the geologic setting of northern Arizona and the active San Francisco volcanic field. Part 2 is a trail guide along the winding Rio de Flag, complete with trail maps.

The 70-page text, authored by Dr. Richard F. Holm, Professor Emeritus at Northern Arizona University, includes 16 maps and 42 photographs and illustrations.
