The Lake Lewis Chapter of the Ice Age Floods Institute will host a chapter meeting and guest lecture with George Last on September 1st, 2026. This presentation will continue the 2026 lecture theme as we explore flood stories along the path from ancient Lake Missoula to the Pacific Ocean. This lecture will feature discussions on our own local feature - Lake Lewis! George Last will discuss the importance of Lake Lewis to our understanding of the Ice Age Floods that repeatedly inundated the Tri-City area. He will examine some of the early geologic studies, Lake Lewis’s pivotal role in the debate over these cataclysmic floods, and some of the latest data from the Tri-City area. This event will be hosted at the REACH Museum in Richland, Washington and is free to the public. No registration required. This event will also be broadcast live. Instructions for joining the Zoom meeting are provided below.

Take a tour of the channeled scablands identifying the diversity of landforms in our area answering the question— ‘Where do we find them and how did they form?” The viewer will leave with a greater appreciation of our unique geomorphology and be able to identify the landforms as they travel through the scablands. |

Glenn Cruickshank, Vice President of the Cheney-Spokane Chapter will give this interesting presentation. Glenn and CWU professor Nick Zentner read over 1,000 field notes of J Harlen Bretz. With these notes, they geolocated over 1,660 sites. This gives us an understanding of the sites Bretz visited and his thought process of interpreting what he saw in the scablands of eastern Washington and Oregon. |

Given the Three Queens, King, and Goat fires in the upper Cle Elum drainage, we are cancelling our September 26 field trip to that area. The end of those fires is not in sight, and we can't even get up into the area to preview a trip. So...lets look to 2027 and we will try to figure out a way to dodge fires, likely by offering our field trips earlier in the year—e.g., April, May, June and July. Mike Horner, Tom Ring, and Karl Lillquist had planned to lead a field trip to the Lake Cle Elum on Saturday 26 September 2026. Plan on ~10am-4pm. They are still working out the details of the trip but it will likely include discussion of: 1) glaciation’s role in shaping the Cle Elum River Valley; 2) Cle Elum River flows pre- and post-dam construction; 3) restoration of the Cle Elum River floodplain; 4) impacts of raising pool level on Lake Cle Elum shorelines; and 5) improving fish passage at Cle Elum Dam. This trip will especially tap into the expertise of Tom who has years of experience working on water issues in the Yakima River Basin (including Lake Cle Elum) and Mike whose M.S. thesis focused on potential shoreline issues associated with a higher Lake Cle Elum. They will provide more details as they solidify the plan. Hope you can join us! |
