If raining or overcast we will NOT go to Mt. Walker, instead, we will meet at the Quilcene city park (just north of US Forest Service office or possibly the back room of the Olympic Timberhouse Restaurant (360.765.0129) in Quilcene (just south of the US Forest Service office

2:15 PM:  Arrive back at Chimacum High School

+++++++++++++++++++++++++++++++++++++

NOTE:

 

Safety First is not just a phrase… based on the nature of this field trip and quarry location requirements, our Geology Group requirements include:

  • Close-toed shoes or boots
  • Hard hat (we will provide)
  • DO NOT go within 50 feet of quarry face/wall
  • DO NOT wander off while in the quarry (quarry will not be in operation, but safety is still paramount!)

ADDITIONAL ITEMS TO BRING:

  • Sack lunch/bevs
  • Rain jackets and layers if cool
  • Notebook/paper for taking notes
  • Camera
  • Hand lens (if you have one, others will share)
  • No need to bring rock hammer (Penny Creek Quarry has a pile of fist-sized rocks if we really want/need a sample to bring home)
  • Small compact camp chairs for during discussions

About the Speakers

Jeff Tepper is a Professor of the Geology Department at the University of Puget Sound.  He received his AB from Dartmouth College and his MS and PhD from the University of Washington, where he studied the origins of granites in the North Cascades.  After teaching on the East Coast for ten years, he joined the faculty at Puget Sound in 2001.  Dr. Tepper’s research uses geochemistry to investigate geologic questions.  He and his students are currently studying the Eocene magmatic and tectonic history of the Pacific Northwest, the environmental history of the Puget Sound area as recorded in lake sediments, and the behavior of heavy metals in sediment.

Ken Clark is a staff of the Geology Department at the University of Puget Sound.  He received his bachelor of science in Geology from Central Washington University and Masters from Western Washington University.  He teaches physical geology and leads senior thesis projects related to basalts and mapping of the eastern Olympic Peninsula.  He is an amazing geologic artist, his maps are typically hand drawn and colored.

Carol Serdar Tepper is a licensed geologist working as a regulator for Washington State.

About the Field Trip

GEOLOGY OF THE FIDALGO, LOPEZ, AND THE SAN JUAN ISLANDS

TRIP OVERVIEW

Day 1. Lopez Island:  

Ferry from Anacortes to Lopez Island. Three stops to see rocks and structures of the Lopez Structural Complex –a major fault zone of the San Juan thrust system. Ferry to San Juan Island in the afternoon.

Day 2. San Juan Island:

Stops at Lime Kiln Point to see rocks transported thousands of miles from the tropics, Cattle Point to see deformed sandstones and siltstones of the Lopez Structural Complex grooved by glaciation, and American Camp to see a major thrust zone.   Ferry to Anacortes.

Fidalgo Island:

Stop to see an assemblage of oceanic crust

FIELD TRIP COORDINATOR:

Jim Aldrich is coordinating the logistics (lodging, transportation, ferry schedules, etc.) for the trip and is the contact for questions.

FIELD TRIP LEADER:

Liz Shermer, professor, Department of Geology, Western Washington University, has studied and published papers on the geology of the islands.

2015-07-18 Michael Machette: Nodule Point field trip

About the Field Trip

FIELD TRIP TO NODULE POINT, MARROWSTONE ISLAND

The Jefferson Land Trust’s Geology Group will lead a walking tour of Nodule Point, which is on the southeastern coast of Marrowstone Island. The trip will be based on a field guide that Dave Tucker of Western Washington University has on his NW Geology Field Trip blog. Please download and read this guide before joining the trip (see registration info to left).

FIELD TRIP: The field trip will be both lay and technically oriented, so although a basic knowledge of geology would help, we’ll have geologists along to explain the features we’ll be seeing and touching. We’ll walk 0.7 miles from E. Marrowstone Road to Nodule Point and then back. You’ll have to be agile enough to get up and down the bluff via a narrow-steep staircase, but the walk is rather easy.

TRIP OVERVIEW: Nodule Point: why it’s there—basalt dike, baked zone, and weathering. Evidence for faulting after dike emplacement. The Scow Bay sandstone, a local building stone Nodules within the sandstone and on the beach. The overlying Vashon (latest Pleistocene) glacial till.

LOGISTICS: When and Where.  Meet by 10:30 am at the home of Greg Lalish, 1101 E. Marrowstone Road. Drive/bike about 600 ft to the east on his access road, where we’ll park on his property. Carpool with others if possible. Then we’ll hike east on Hoyt Road (Private) and drop down to the beach via a private staircase. Bicyclists can go directly to the access point at 501 Hoyt Road (arrive at 11:00 am).

Access: Trip will be along a private road (Hoyt) and through private property. Adults and children over 12 only please, no dogs.
Space: Trip size is limited by parking and staircase access. Max. will be 50 or less. Sign- up for the trip is on a first-come basis, bicyclists get priority (because of parking issues).

No cost, just become an avid supporter of the Jefferson Land Trust. Bring: Wear footgear that protects your ankles. Hat, light jacket, water, bag lunch, camera, notepad, etc. We’ll go no matter what the weather, so be prepared. We’ll eat lunch on the beach.
