Cougar Divide field trip updated


Pale dikes intrude Nooksack Fm. at the head of Dobbs Creek.

I hiked Cougar Divide again on September 12, and have updated the field trip guide. You can read it here. This is the easist and best place in the area to see intrusive dikes.

The updated guide includes these changes: better directions to find the oldest dated rock in the Mount Baker volcanic field, a rhyodacite dike, and the GPS coordinates have been changed slightly; a new photo added showing the dikes at the head of Dobbs Creek.

The ridge is beautiful. I noticed that there was some hoar frost on the trail in a few places, and there are patches of fresh snow on the snow slopes below Chowder Ridge. Take an ice ax to reach Chowder, as there is a short section of firm, steep, and exposed snow to cross just below the ridge.
