Ellensburg Chapter

Spectacular Coulees and Channels

coulees, channels, petrified forests

The Ellensburg Chapter includes the area of the Quincy Basin at the southwest end of the Grand Coulee and the Telford-Crab Creek Scabland Tract.

The Floods flowing south across the Quincy Basin carved out the broad Drumheller Channels area, and those spreading west to the Columbia River carved out the Frenchman and Potholes Coulees.

As the flood waters backed up behind the downstream constriction at Wallula Gap the waters of temporary Lake Lewis filled part of the Quincy Basin, depositing fine grained Palouse materials that had been stripped off the more northerly portions of the Floods path.

The present day Columbia Basin Project diverts water south from the Columbia River at the Grand Coulee Dam to provide irrigation that transforms this soil in a high desert environment into a rich and abundant garden.

The Ellensburg Chapter area includes many other geologic wonders including the Gingko Petrified Forest, the Saddle Mountain and Frenchman Hills anticlines, as well as the features of the Mt. Stewart Range.

History of the Ellensburg Chapter

Tom Foster was the person responsible for the formation of an IAFI chapter in Ellensburg, WA along with scientific and technical advisors Karl Lillquist and Nick Zenter. Karl is a physical geographer at Central Washington University. Nick is a geologist at Central Washington University.

When Tom’s job transferred him out of the Ellensburg area, Nick and Karl assumed the leadership of the chapter. They served as president and vice president respectively from 2008 until 2021. The chapter was officially accepted by the IAFI in April, 2008. It had met regularly since February, 2007. Attendance has been excellent at the many lectures and field trips conducted all these years. A great diversity of interesting speakers entertained and educated people attending the lectures.

The chapter is on the northwest margins of the ice age floods with only about one third of the area affected by them. For this reason, chapter lectures and field trips cover a greater diversity of geology and landscapes than just those associated with the ice age floods. 

On Saturday September 15, 2012 the chapter hosted the annual meeting for the IAFI and conducted a field trip of the Ellensburg Area. Field trip leaders were Karl Lillquist from the Geography Department of Central Washington University, Nick Zenter from the Geology Department at Central Washington University and Ryan Karlson from Washington State Parks.

In April, 2024 Mike Doran was elected as the second president of the Ellensburg Chapter. Tom Ring isvice president and Karen Martens is the Treasurer.
