What is the Bretz club?
We are pleased to invite you to the 7th Annual 'Bretz Club', held at Rock Springs Ranch, Tumalo, Oregon.

The 2016 conference (dubbed “Flows on Flows”) starts with your early evening arrival on Thursday May 12. No dinner will be provided. The lodge has 30 rooms with Queen beds, so you’ll be sharing a room (we’ll work roommates out later) or you can volunteer to camp.

The technical program begins Friday, May 13th, with three keynote talks by Marshall Gannett (USGS), Andrew Meigs (OSU) and Daniele McKay (UO/OSU). You will also have your chance to make a contributions to our collective geomorphic thinking during a pop-up session (short 3 minute presentations on quite literally anything from gemorphic musings to announcements to 3MT). Friday evening we’ll have a poster session, along with scientific (and non-scientific) socializing, including our inexplicably popular raffle of participant-donated geomorphic items. If you are musically inclined, review and contribute to the Bretz song-book!

On Saturday, May 14th, Andrew Meigs et al. will lead us on a three stop field trip exploring the interrelationship among faulting, volcanic, and landscape evolution along the Sisters fault zone. The field trip will end around 4pm, but participants may depart at any time.

This year's cost for the 2-day (2 night) conference is $150 for professionals and $85 for students. If you register as a student you will be asked to fill a volunteer position during the conference. Registration is handled through OSU Conference Services. If you have any questions about billing please contact them directly.

Notes about registering this year:

  1. It’s a new system.  If you are not affiliated with OSU (and maybe even if you are) you will be prompted to create a profile before you can register.
  2. While the queen bed comes with linens, we are sleeping 2 to a room. You may prefer to bring your own sleeping bag, pillow and draw straws to see who sleeps on the floor if you are not planning to share the matress.  There is also a camping option.
  3. Please BYOB & snacks for evening happy hour. 
  4. Consider donating an item of geomorphological interest to our raffle. Ticket are $5 each and help keep registration costs low.

Interrelationships between extension, volcanism, and landscape evolution along the Sisters fault zone and NW Rift of Newberry Volcano

Leaders: Andrew Meigs, Ellen Lamont, Danielle McKay and Marshall Gannett

Departure Time 8:30 am (breakfast at 7:30 am), you'll pack a sack lunch to take with you. We will not be returning to the Ranch.  Parking for stops 1 and 2 will be at the Lava Butte Visitor Center between Bend and Sunriver to the west Hwy 97, with a 15 min walk between stops (a driving option is available) .

Early departure is possible and easy at any time.

Stop 1: Lava Butte and 7 ka eruptive events.  Field trip introduction, Holocene volcanism, and lava and volcano geomorphology.  

Stop 2: Structure of the NW rift and relationship to the Sisters fault zone; fault scarp degradation; fluid flow and fault zones; evidence for Holocene earthquakes.

Stop 3: Structural and volcanic interaction with Deschutes River; transient river response to volcano damming, channel width and stream power, and knickpoint migration.
