9:00 AM:  Brief introduction to basalt (if raining, we’ll go to HJ Carroll Park, 9884 WA-Hwy 19, Chimacum, WA 98325); awaiting Matt Tyler 360.385.9129 call back for permission)

9:30 AM:  Depart Chimacum High School

9:45 AM:  Arrive at New Shine Quarry (9861 State Route 104, Port Ludlow, WA


10:45 AM:  Depart quarry

12:15 PM:  Depart quarry

12:30-1:30 PM:   Mt. Walker* (north side) Lunch and Big Picture Basalt conversations (do we want people to bring camp chairs to sit on?)

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




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!)


  • 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.
