AZGS geologists Joe Cook [right] and Mike Conway joined participants of the 3-day Water Education Foundation field tour to earth fissures today at the southern end of the Casa Grande Mountains -- near the intersection of S Sunland Gin Road and W Hauser Road -- to describe the impact of ground water overdrafts on subsidence and earth fissure formation in alluvial basins of south-central Arizona.
The Water Education Foundation, a nonprofit organization headquartered in Sacramento, CA, is leading a three-day tour of 51 individuals from state and federal agencies, industry, and nonprofits across southern Arizona exploring water and water-use challenges facing Arizona in the 21st century.
