Registration is now open for a field trip to the site of the ice dam that caused the formation of Glacial Lake Missoula multiple times during the Pleistocene period.

April 17 - Participants will travel independently in personal vehicles to overnight in Sandpoint ID. Remember that Sandpoint, ID, is in the Pacific time zone.

April 18 - All participants will travel together in a bus with Tony Lewis, local floods expert and president of the Coeur du Deluge chapter, to Clark Fork and various other nearby sites, returning to Sandpoint at the end of the day. The bus is scheduled to depart from the Selkirk Lodge at 9:00 and make an additional stop at the Red Barn Park n Ride at the base of the mountain. A more complete field guide will be available to download in advance or can be picked up at check-in.

April 19 - Those interested in visiting sites further downstream will travel in a caravan of personal vehicles, meeting at Farragut Park at 10:00 am for interpretation at that location and your own lunch. Participants could then decide to continue to Spirit Lake, Newport, Kettle Falls and even the rest of the way to Spokane for an additional overnight on your own, or return to Sandpoint, or return home to Missoula at any point. All roads are paved. Surface parking is available at no charge at Schweitzer Resort. Underground parking is offered at a cost of $15 daily. Please arrange to carpool if possible.
