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.

SPACE AND COSTS
Limited Space: Space is limited on this trip to 23 persons as only five cars (each holding 5 persons) can be accommodated at certain stops. Sign-up for the trip is on a first-come basis.
Costs: A $50.00 trip fee, per person, is being charged to cover the Geology Group’s operational costs. Persons will be added the trip list on receipt of their $50.00 fee. The fee is non-refundable should one withdraw from participating. The fee does not cover the cost of lodging or meals. Lodging has been reserved on San Juan Island for Saturday the 19th. Cost for rooms are under $90.00, have full or queen beds and may be shared with another person.

Jim Aldrich, who has been working on a geologic investigation of the structure geology and tectonics of the mountains for three years, was the trip leader.

Original announcement: The trip will originate and end at the Olympic National Park visitor center on the south side of Port Angeles. The trip starts at 9:00 am Saturday, September 14. The first day we will be stopping at outcrops of the Olympic Subduction Complex (OSC) Lower unit on the Pacific Coast and the oldest strata of the Coast Range Terrane on the north flank of the mountains. We will stay at a motel in Port Angeles that night. The second day we will be examining outcrops of the OSC Upper unit in the core of the range and the upper strata of the Coast Range Terrane along Hurricane Ridge Road. The longest walks to outcrops are two that are about 1/4 mile down a moderate grade. All other stops are at outcrops across a road. The field trip will end by 5 pm September 15th. Costs: There is no trip fee. Participants will have to pay for their own motel room, or the cost to share a room if they are willing to do that, and meals.

This field trip includes stops to observe and hear about the geology of the three major rock sequences of the Olympic Mountains – from the Pacific Coast to the core rocks on Hurricane Ridge.

2013-09-14 Jeff Tepper: Deformed coastal seds

September 13, 2013October 1, 2022 QMPGEOeditor1

This is the first of two days of geologic field trips to the Northwest part of the Olympic Mountains. Jeff Tepper and Carol Serdar Tepper will lead a car-caravan trip with 24 participants to several West Coast beaches review the structure and stratigraphy of the area, much of which is comprised of deformed offshore sediments emplaced by subduction beneath the Olympic Mountains by the Cascadia subduction zone. There is no formal guide for the trip, but handouts will be distributed. See Day 2 of the trip (09-15-2013) to Hurricane Ridge.
