Cheney-Spokane Chapter Hike – Palisades Park 2026
Palisades Park 2-198 S Rimrock Dr, Spokane, WA, United StatesThe 3-mile hike will be led by IAFICS board member geologist Michael Hamilton. It will take place along Rimrock Drive, which has spectacular views of Spokane and the Spokane Valley. The Glacial Outburst Flood Story will include a lot of "arm-waving," pointing out flood features both along the trail and with views to the east. The geology discussion will include details of another kind of flood that hit the Spokane area 14 million years ago. The hike will then cut to the west along one of the park's trails to find mysterious Mima mounds, and then loop back to the parking area.

Lower Crab Creek Field Trip
CMSP&P Bridge, Beverly, WA 46.83539588686751, -119.93816967222578, Beverly, WA, United StatesSaturday April 11—Lower Crab Creek. We will meet on the east end of the Chicago, Milwaukee, St. Paul & Pacific bridge in Beverly at 10:00am. Over the day, we will explore: 1) the tectonic origins of Crab Creek “Coulee” and the Saddle Mountains; 2) impacts of Ice Age flooding on the area; 3) formation of prominent rockfall and landslides from the Saddle Mountains; and 4) how geology, weather and climate, and human activity have shaped sand dunes and salt flats in the area. The trip will conclude around 3pm giving participants plenty of time to get back to Ellensburg for Nick Zentner’s lecture. More details will be forthcoming. Field trip leader Karl Lillquist.

Hayden: Dating Erratic Boulders: How Long Ago Were the Floods?
Hayden Library 8385 N Government Wy, Hayden Lake, IDHow do geologists know when the ice age floods actually occurred in the Spokane area? One method is to date the large flood-rafted erratic boulders. We explore the ages of the floods and the methods used to determine their dates and present newly gathered dates from the Spokane region revealing when the floods happened. Presented by Glenn Cruickshank, vice president of the Ice Age Floods Institute (IAFI), Cheney-Spokane Chapter, and Dr. Jim O'Connor, USGS Registration is required. It will be linked here as soon as it has been posted to the library website.

Spirit Lake: The Ice Age Missoula floods and the Spirit Lake giant current dune field
Spirit Lake Library 32575 N 5th Ave, Spirit Lake, IDGiant Current Dunes or MegaRipple Marks – One of Bretz’ most important pieces of evidence for catastrophic flooding was the “giant current dunes.” These large-scale bedforms appeared as patterns of parallel ridges and swales on many aerial photographs in the flood channels in the scabland of Washington, but had escaped recognition from the ground because of their size. Giant Current Dunes are visible west of Clark Fork near Castle Rock; however, the most prominent and visible Giant Current Dunes are located several miles east of Spirit Lake along Hwy 54 where the highway cuts through the dunes showing their undulating profile. The location of many of the telephone poles on the crest of these dunes accentuates these landforms. The dunes form transverse to the current direction, and form cusps that are convex upstream, with arms that point downstream. Furthermore, the size of the cusps appears to decrease in the direction of lower velocity. Internally, the dunes consist of gravel and pebble foresets. Giant current dunes exhibit an asymmetrical profile with the downstream (lee) slope steeper than the upstream slope. Crests range from 20 to 200m apart and heights range from 1 to 15m (Baker and Nummedal, 1978) and are among the largest measured throughout the Floods area. The Spirit Lake current dunes can also be easily recognized from the air by their characteristic pattern, accentuated by vegetation. This dune field is immediately in the path of the breakout from Lake Pend Oreille, and experienced some of the highest energy flows.
