Greg Sherman has the answers to many questions people have asked recently: What is a Coal Mine? What is subsidence? Why should I be concerned about subsidence? Why are developers concerned?
Greg is a certified gerologist who has been studying the effects of coal mining on the landscape and development. Among his many publications are “Geology and Mining History of the Boulder/Weld Coal Field” and “Assessment of Subsidence Damage to Existing Structures in Louisville, Lafayette, Colorado”.
To help us understand subsidence, the Erie Historical Society invited Greg to discuss this topic on Thursday, May 22 at 7p.m., at the Erie Middle School, Erie, Colorado. This event is sponsored by the Erie Historical Society so there is no charge, however donations are appreciated.
