Field Courses

Field Course Disclaimer:

Field courses will be filled on a first-come, first-served basis, and registration will be limited to the number of spaces shown. The indicated minimum and maximum numbers of participants are based on a combination of factors, including transportation, accessibility, and safety at roadside outcrops. Field courses are subject to cancellation if minimum number of registrants is not met. Field course logistics (e.g., schedule, duration, route, transportation, location/number of stops, etc.) are also subject to change. Participants should be prepared for variable weather conditions and hiking on uneven ground.  Field courses will proceed rain or shine. Additional information regarding the logistics of each field course will be provided to the paid registrants by the field course leader(s) at a later date, but well in advance of the course. 

 

Field Course #1:  Landslides and Engineering Geology in the Columbia River Gorge

DATE:

Tuesday, 9/15/2020 

 

TIME: 

Departs at 8:00am and returns at 5:45pm. Departs from the Hotel Lobby.

 

COURSE LEADERS: 

Kate Mickelson, Will Gallin, Doug Anderson

COST (per person): 

$120 before 8/1/20, $145 after 8/1/20 

 

ATTENDEES: 

Minimum 25 ; Maximum 47

ACTIVITY LEVEL 

 

This trip will focus on the geology, waterfalls, landslides, rockfall, and ice-age floods. We will also have stops discussing the history of the historic Columbia River Highway and a recent wildfire in the Columbia River Gorge. Visit iconic vistas such as Chanticleer Point and the Vista House with lunch at the Port of Cascade Locks, directly across from the enormous Bonneville landslide! In the afternoon, we will cross over to the Washington side of the Gorge to visit two giant landslides with historic, spectacular movement.

Field Course #2: Living with Giant Landslides in Portland, Oregon

DATE:

Tuesday, 9/15/20

 

TIME: 

Departs at 8:00am and returns at 5:30pm. Departs from the hotel lobby.

 

COURSE LEADERS: 

Charlie Hammond, Landslide Technology

 

COST (per person): 

$135 before 8/1/20, $160 after 8/1/20

 

ATTENDEES: 

Minimum 21 ; Maximum 40

ACTIVITY LEVEL 

Giant landslides in the Portland metropolitan area have been impacting our infrastructure for decades, with one notable case starting in the 1890s. Our region is made up of many types of geologic materials, such as but not limited to submarine and flood basalts, soil interbeds, volcaniclastic rock, mudstone to sandstone and conglomerate, and glacial loess.  Tectonic tilting, folded and faulting, combined with various condition weathering and decomposition, and high groundwater often results in landslides.  When development is constrained by unstable ground, along with the social and economic factors of the urban area, landslides need to be engineered.

 

Field trip is conceptualized to visit two to three giant landslides in Portland, Oregon and to explore:

·       Site engineering geology conditions

·       Historic impacts

·       Evolution of geologizing and engineering landslides

·       Mitigation measures and monitoring systems

Field Course #3:  Mt St Helens - Highlights of the 1980 Eruption and Engineering Geology after the Event

DATE:

Saturday, 9/19/20

 

TIME: 

Departs at 8:00am and returns at 5:30pm. Departs from the hotel lobby.

 

COURSE LEADERS: 

Scott Burns, PhD, Portland State University

 

COST (per person): 

$120 before 8/1/20, $145 after 8/1/20

 

ATTENDEES: 

Minimum 25 ; Maximum 48

ACTIVITY LEVEL 

Join Dr. Scott Burns on an all day field trip to Mt. St. Helens, the most studied volcano in the lower 48 states!  We will leave at 8 AM and get back about 5:30 PM.   We will visit the Mt. St. Helens Visitor center, the Sediment Retention Dam, three outcrops, four overlooks and then the David Johnston Visitor Center.  We will learn about the famous 1980 eruption and the recovery of the area.  We will see how engineering geology was used over and over again to not only build Highway 504, but the Spirit Lake Tunnel and the evaluation of landslide hazards there.

Field Course #4: Scoggins Dam Engineering Geology in the Cascadia Subduction Zone / Networking Opportunity

DATE:

Tuesday, 9/15/20

 

TIME: 

Departs at 8:00am and returns at 3:00pm. Departs from the hotel lobby.

 

COURSE LEADERS: 

Bureau of Reclamation: Bryan Simpson, Cassandra Wagner, Todd Maguire

USGS: Dr. Ray Wells

 

COST (per person): 

$100 before 8/1/20, $125 after 8/1/20

 

ATTENDEES: 

Minimum 25 ; Maximum 50

ACTIVITY LEVEL - Easy

Scoggins Dam is a zoned earthen embankment dam located on Scoggins Creek, West of Portland.  It is owned and operated by the Bureau of Reclamation.  This trip will focus on the site geology with a discussion of the recent geologic/geotechnical field exploration program by Reclamation in support of seismic risk-based design modifications. This trip will also feature a presentation by Dr. Ray Wells, USGS Research Geologist Emeritus and Cascadia megathrust expert, discussing the Cascadia Subduction Zone (CSZ) and its impact to assessing seismic risk for infrastructure in the region. There will be various stops, discussing the Scoggins Dam Facility and a box lunch served onsite. A Networking Event will be held at the McMenamines Cornelius Pass Roadhouse Brewbpub in Hillsboro, on the way back to Portland.
