Dave Roddy

Dave Roddy was a world-renowned scientist at the forefront of investigators studying impact and explosion craters. His field mapping of Flynn Creek was the first mapping detailed enough to demonstrate the impact origin of an ancient structure in North America. David was an authority on the Meteor Crater impact structure, east of Flagstaff. Dave's work has assisted in the...

Raymond Milner Batson

Ray Batson was born in Lincoln, Nebraska, on 8 July 1931. His lifelong passion for flying surfaced early. In high school he worked at Stapleton Airfield in Denver refueling planes in order to pay for flying lessons, and obtained his private pilot’s license. After a year of study at Regis College, he enlisted in the United States Air Force and served a two-year tour of duty as...

Gene Shoemaker - Founder of Astrogeology

He once said he considered himself a scientific historian, one whose mission in life is to relate geologic and planetary events in a perspective manner. A modest statement coming from a legend of a man who almost single-handedly created planetary science as a discipline distinct from astronomy. He brought together geologic principles to the mapping of planets, resulting in...

1961: USGS Astrogeology's First Published Map

The race to the moon began on August 17, 1958, and the Soviet Union won. This isn't the opening line of an alternate history story; rather, it is an acknowledgment that more than one moon race took place. The first, with the goal of launching a small automated spacecraft to the moon, began with the liftoff of the Able 1 lunar orbiter, a 38-kilogram U.S. Air Force (USAF) probe...

Accounting for Consumptive Use of Lower Colorado River Water in Arizona, California, Nevada, and Utah

In the Colorado River valley between the east end of Lake Mead and the international boundary with Mexico (see figure), the river is the principal source of water for agricultural, domestic, municipal, industrial, hydroelectric-power generation, and recreational purposes. Water is stored in surface reservoirs and in the river aquifer---permeable...

Method to identify wells that yield water that will be replaced by Colorado River water in Arizona, California, Nevada, and Utah

Accounting for the use of Colorado River water is required by the U.S. Supreme Court decree, 1964, Arizona v. California. Water pumped from wells on the flood plain and from certain wells on alluvial slopes outside the flood plain is presumed to be river water and is accounted for as Colorado River water. A method was developed to identify wells...
