SUMMARY:Cheney-Spokane Chapter Hike – Palisades Park 2026
DESCRIPTION:The 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. \n  \n \n \n

SUMMARY:Hayden: Dating Erratic Boulders: How Long Ago Were the Floods?
DESCRIPTION:How 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.  \nPresented by Glenn Cruickshank\, vice president of the Ice Age Floods Institute (IAFI)\, Cheney-Spokane Chapter\, and Dr. Jim O’Connor\, USGS \nRegistration is required.

SUMMARY:Spirit Lake: The Ice Age Missoula floods and the Spirit Lake giant current dune field
DESCRIPTION: Giant 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.  \nGiant 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. \nGiant 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. \nPresented by Dr. Linda McCollum\, president of the Ice Age Floods Institute (IAFI)\, Cheney-Spokane Chapter \nRegistration is required. It will be linked here as soon as it has been posted to the library website (https://communitylibrary.net/library/spirit-lake/).

SUMMARY:Bretz Was Right: A Pre‑Birthday Floods‑Fest
DESCRIPTION:Save the date! \nOur chapter is planning a special late‑summer gathering on Saturday\, August 29\, in honor of J Harlen Bretz\, whose birthday falls just a few days later (September 2). Bretz’s groundbreaking work on the Ice Age floods reshaped the scientific understanding of the Northwest—and we think that deserves a celebration. \nWe’re still shaping the details\, but expect a relaxed\, community‑friendly event that highlights Bretz’s legacy and the remarkable landscapes he helped the world understand. More information will be posted as plans develop. \n \n \n  \nHe mapped the scablands bold and bright\,\nSaid “Floods did this!” with all his might.\nFor thirty years they told him “No”…\n’Til evidence began to flow. \nSo join us as we celebrate\nThe man who made the floods make sense —\nA pre‑birthday bash for J Harlen Bretz\,\nWho proved the skeptics wrong (immense!). \n \n
