The Arizona Geological Survey celebrated its 125th anniversary in 2013, tracing our origins back to the creation of the Office of Territorial Geologist in 1888, 25 years before Arizona became a state.
On this, the 125th Anniversary of the Arizona Geological Survey (AZGS), we are celebrating the work of hundreds of geoscientists who struggled to understand and reconstruct Arizona’s geologic past.
In a jargon-free article written for the general public, former Arizona Geological Survey Director Larry Fellows summarizes the nature and societal scope of geologic hazards in Arizona.
This marvelous article includes 17 black and white original photographs by Peter Kresan that capture the destructive nature of the October 1983 floods along Rillito Creek, Pantano Wash and the Santa Cruz River of Tucson and environs.
