Meet G.K. Gilbert and learn about his studies of Meteor Crater during July 11 Living History program9 Jul 2010, 18:40 UTC
Sunday July 11, 7 p.m. Wrong for the Right Reasons: G.K. Gilbert and the Origin of Meteor Crater. Lowell Observatory Visitor Center.
Geologist Grove Karl Gilbert was among the greatest geologists in American history. Among many other contributions to geology, Gilbert was the first to suggest that the crater at Coon Butte, Arizona Territories (now called Meteor Crater) was caused by a meteorite impact. After conducting field work studying the crater in 1891, Gilbert concluded that he was incorrect, and that a volcanic steam explosion was most likely responsible for the crater. This conclusion triggered a controversy over the origin of the crater that wasn’t completely resolved until the 1950’s.
The year is 1894, and we’ve invited Gilbert to take a break from his duties as chief geologist for the United States Geological Survey in Washington, D.C., and come to visit the brand new observatory founded by Percival Lowell here in Flagstaff. Gilbert will discuss his recent publication “The Moon’s Face,” and share his as yet unpublished observations on the origin of Coon Butte. Following Gilbert’s departure Dr. G. Kent Colbath will summarize the discoveries made at the crater after Gilbert’s study, with particular emphasis on the work of Daniel ...
