Deep Lake Potholes Field Trip

Sun Lakes State Park Deep Lake Parking Lot (47.58848153536495, -119.34090712166719), WA, United States

Join Sun Lakes-Dry Falls State Park Rangers for an eye opening field trip to the Deep Lake Potholes in Sun Lakes State Park on Saturday, Sept 16. We will meet in the Deep Lake parking lot at 10:00 AM. Discover Pass is Required. Years ago, Tom Foster blogged about his visits to these incredible potholes: I must have stood at this spot for 15 minutes Saturday - Amazing Ice Age Flood features surrounded me. In this shot the pothole, massive butte and hanging coulee all help one visualize the awesome power of the Ice Age Floods. I'm impressed with the large basalt overhang near the skyline. In Bruce Bjornstad's book "On the Trail of the Ice Age Floods" he describes this undercutting process that was key to the formation of vertical faces in recessional cataracts. The Interpretive Master Plan for the Ice Age Floods in Washington State Parks describes this group of kolk carved depressions - "Another spectacular feature is a tight cluster of the deep potholes beyond Sun Lake just west of Deep Lake. These potholes lie along the valley bottom and require only a 5-10 minute walk from the road." I'd also like to mention that a fall into one of these potholes could be fatal!

Cheney-Spokane Chapter Fishtrap Lake Field Trip / Hike

Fishtrap Lake South Loop

Fishtrap Lake, Washington (BLM Photo) Come join us for a 5-mile hike to explore the Ice Age floods features in the Fishtrap Lake area east of Sprague, WA! The Cheney-Spokane Chapter of the IAFI is scheduling a hike at Fishtrap Lake on Saturday, October 14th. The hike will be led by Don Chadbourne and Chris Sheeran, geologists and board members of the Cheney-Spokane Chapter. Description of Fishtrap Lake Hike We will begin and end at the Fishtrap Lake South Loop Trailhead. The hike will follow the South Loop trail, with a total length of about 5 miles. The trail is mostly single track over dirt and rock, with an elevation gain and loss of about 500 feet. Along the way we will have an intimate view of the channeled scablands that were carved out by the ice age floods and see features including pothole lakes, rock benches, Mima mounds, kolks, and streamlined and scarped Palouse hills. The hike will also provide wide open views of Fishtrap Lake and the surrounding country. This hike is included in On the Trail of the Ice Age Floods – Northern Reaches, by Bruce Bjornstad & Eugene Kiver, but we will be following trails that were constructed after the book was published. Directions to the trailhead From I-90 take Exit 254 and proceed south 3.6 miles on the Sprague Highway. Turn left (east) on Miller Ranch Road and proceed 0.2 miles to the “T” at the Miller Ranch house. Turn right (south) and drive 0.8 miles to the trailhead parking lot.
