Geology Field Trip gift certificates from MBVRC

Cross country trip to Schreibers Cinder Cone.

Cross-country trip to Schreibers Cinder Cone.

Mount Baker Volcano Research Center is offering gift certificates for geology field trips.  These make great gifts for your geophile friends and relatives. The cost  is $75 (the usual cost of a one day guided trip, including van transport) and can be applied to any field trip offered by MBVRC. This year there are plans to offer  trips to lowland sites in Northwest Washington in the late winter/early spring. In the summer, trips will go to locations around Mount Baker , and a multi-day trip to Mount St. Helens is in the early planning stages.

To purchase a gift certificate, send an email or letter to MBVRC. Include  the name of the person the certificate is for, as well as your mailing address. You may send payment via check payable to ‘MBVRC’ to  708 13th St, Bellingham, or use the MBVRC PayPal account – the account code is this email address:

You will receive a nicely printed gift certificate in the mail. Field trip fees beyond expenses go to the MBVRC research and education fund. To see brief descriptions of some  past geology field trips, scroll down here: http://mbvrc.wordpress.com/field-trips/

Sign up for geology trip- Ptarmigan Ridge, Mount Baker

We'll learn how platey jointing and columnar jointing forms.

Dave Tucker will lead a one-day geology hike on Ptarmigan Ridge, near the Mount Baker Ski Area. The trip is organized by North Cascades Institute.

September 29, all day. $95 includes trip guide and transport from Glacier Ranger Station.

This hike will explore the gorgeous volcanic landscape on the east side of Mount Baker- Kulshan caldera ash flow tuff, post-caldera rhyolite domes, Table Mountain and Ptarmigan Ridge lava flows, volcanic ash deposits (Baker and Crater Lake). Mount Shuksan is just east of us, so we can also discuss terrane accretion. The hike is above tree line on the Ptarmigan Ridge Trail, elevation gain is around 500 feet, total round trip distance of 10 miles but probably less. There are 6 spaces left for this trip. The September 28 trip is full.

There is a description of ongoing dramatic changes to the new debris flow deposits in the Middle Fork Nooksack over on the MBVRC blog. There has been a second debris flow, on June 6th.

Geology field trips offered by North Cascades Institute

I will be leading three field courses on behalf of North Cascades Institute in late summer of 2013.Also, my friend David Williams will lead an urban geology tour in Seattle.

Migmatite in the Diablo Overlook road cut? What's 'maigmatite'? Sign up to find out!

August 9-11: GEOLOGY OF THE NORTH CASCADES: CROSS SECTION THROUGH THE CRUST. This course will be based out of the NCI Environmental Learning Center at Diablo Lake. Over three days we will examine different sites along Highway 20 from Sedro Woolley to Washington Pass. Meals and lodging at the Learning Center.

Kuslhan caldera, Mount Baker, and Table Mountain volcanics can all be examined along the Ptarmigan Trail.

Kulshan caldera, Mount Baker, and Table Mountain volcanics can all be examined along the Ptarmigan Trail.

September 28 and repeated on September 29: MOUNT BAKER: THE STORY OF VOLCANOES I AND II. I will lead a one day hike along Ptarmigan Ridge on the east flank of Mount Baker.We will look at volcanic deposits from the Kulshan caldera, pre-Mount Baker andesite volcanoes, and young Baker itself. These two hikes will fill up VERY QUICKLY so register right now if you are interested.

In downtown Seattle, see 3.5 billion year old Morton gneiss, probably the oldest building stone in the world!

Also on September 28, David Williams leads ‘Street Smart Naturalist’. This will be a walking tour of downtown geology. highly regarded and a must for Seattle residents interested in geology.

Registration and descriptions for all these programs begins at the NCI geology webpage.
