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 ‘migmatite’? 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.

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.
