A Mount Baker field trip guide for the Northwest Geologic Society is posted on their website. To find the pdf, go to the Field Trips pages on this blog; the link is at the top. The guide includes maps and color photos.
The trip guide is written by Dave Tucker (WWU) and Kevin Scott (USGS). The two-day trip was held in September 2010. It visited the Baker Lake side on Day 1- Holocene lahars, the Sulphur Creek lava flow, and tephras. Day 2 of the guide visits the volcano’s north east flank: Heather Meadows, the Kulshan caldera, and Pinus Plateau lava.
