Saddle Mountains IAFI field trip.

Sentinel Gap - Columbia River course through the Saddle Mountains


Sunday, October 26, 2014. 10:00 am - 6:00 pm.
Carpool. No reservations needed. No cost. Everyone welcome!
Nick Zentner, field trip leader.

We’ll depart at 10:00 am (sharp!) from CWU's Hebeler Hall parking lot (H6). Bring snacks, water, sturdy shoes, layers of clothing, and a pleasant disposition. Some field stops include a few hundred yards of hiking.

Vehicles (2WD is fine) require high clearance. Gravel/Dirt roads for Stop 3 and Stop 4. Glorious views at these stops! If the weather is foggy/low clouds….these stops will suck.

You’re invited to join our study of the Saddle Mountains. Detailed geologic mapping by Steve Reidel (1988) will be featured throughout the trip. In addition to bedrock layers and faults/folds, we will look at evidence for Ice Age Flooding and an old Columbia River course along the base of the Saddle Mountains.

Homework: Study Reidel’s maps (field trip guide) before October 26 to get the most out of our trip! (crayon coloring by Nick).

Snoqualmie Pass and Keechelus Lake

Here’s Karl:

"In the relatively recent geologic past, glaciers were common in the Upper Yakima River Watershed. Most of the glaciers are now gone but their impacts linger. Contemporary transportation routes, water quality and quantity, logging and farming practices, sites of mining operations, and recreation opportunities all are shaped by past glaciation. Join us as we explore the landform and sediment evidence of past glaciations in the Upper Yakima River Watershed. The trip will include field stops at Swauk Prairie, Lake Cle Elum, Domerie Flats area, Swamp Lake, Snoqualmie Pass, and Alpental.

Several of the stops will include short (< 1/8 mile) walks.

Please bring appropriate clothing for September weather in the Eastern Cascades - it could be sunny, warm, and dry or it could be cold and wet. Our last several stops will be at over 3200 feet elevation. Also, make sure to bring lunch or snacks and drinks. We will take time for lunch on the shores of Lake Cle Elum.

FIELD TRIP GUIDE

Grand Coulee - Million Dollar Mile.
"Million Dollar Mile" - Grand Coulee

Million Dollar Mile: The Coulee City to Grand Coulee highway was moved from the floor of Banks Lake to the east side of the Upper Grand Coulee in the early 1950’s. In this area, construction crews had to blast through basalts to remain above Banks Lake. The costly construction linked to this blasting gives this stretch of the road its name.

Ellensburg, Washington sits at a geological crossroads – making it a perfect place to study an intoxicating variety of geology and physical geography. Within an hour’s drive from the CWU campus, students of all ages can learn hands-on lessons of the Columbia River Basalts, Cascades volcanism, Ice Age Floods landforms, plant fossils of the tropical Eocene, Ellensburg blue agates, the Yakima Fold Belt, among other local wonders.


Amazing geology surrounds Ellensburg


Clockwise from the Davidson tower:
  • West Bar giant current ripples-On display downstream from Wenatchee along the Columbia River, these photogenic ripples are well-known among Ice Age Floods experts around the world.
  • Ginkgo State Park-15 million-year-old petrified logs sit on basalt cliffs overlooking the Columbia River near the town of Vantage.
  • Columbia River Basalt-More than 300 basaltic lava flows flooded the Pacific Northwest time after time 7-15 million years ago - burying forests, changing river courses, and loading the crust of the region.
  • St. Helens-Awakening famously on May morning in 1980, the mountain woke again in 2004 building an impressive lava dome tucked inside its crater.
  • Rainier-Many geologists are concerned about Mt. Rainier-related natural hazards that threaten residents of the Puget Sound. Will there be volcanic mudflows flowing down river valleys in our lifetime?
  • Lahars (volcanic mudflows)-of the Ellensburg Formation perch above the Sunset Highway west of Ellensburg near the village of Thorp. Geologists continue to debate which extinct volcano is responsible for these deposits.
  • Central Cascades alpine peaks.(photo shows summit of Mt. Stuart)-93 million-year-old granodiorite dominates the geology of Mount Stuart - one of many peaks of the Central Cascades. Granodiorite forms when magma solidifies underground beneath volcanoes. So what happened to the volcano?

Ellensburg IAFI Chapter President
Hosts Geology Program

"Central Rocks", a geology talk show hosted by CWU Geologist Nick Zentner, has been in production since October of 2006. Broadcast in central Washington on KCWU-TV, the show regularly features faculty and staff at the Department of Geological Sciences at Central Washington University. Special episodes have featured visits from noteworthy regional geologists including Ice Age Floods author Bruce Bjornstad, Tsunami expert Brian Atwater, and Mount Rainier geologist Tom Sisson.

UPDATE: 2013 MUCH BETTER!!! Very little trash found around pool in December.

Click above to view example of trash found along edge of pool - bottom of Palouse Falls (December 2012). Good news to report ... some areas downstream from the main plunge pool (that were loaded with trash in 2011) were almost litter-free! Bad news is ... main pool shoreline was a mess! Let me know if you want to help Fall of 2014.


Ellensburg Ice Age Floods Institute members launch canoes and kayaks to explore Cooper Lake during a recent field trip.

Ellensburg Chapter members (and anyone else that wanted to tag along), launch watercraft to explore the Cooper Lake area. Field trip leaders Karl Lillquist (CWU) and Jack Powell (DNR) described general geology of the eastcentral Cascades, the glacial origins of the lake, impacts of global warming on present glaciers upstream of the lake, and recent modification of the lake by fire, flood, debris flow, and avalanche.
