Pinus Lake columnar andesite, Mount Baker volcanic field

As promised, I’ve published a field trip to the 202,000 year old Pinus Lake andesite east of Nooksack Falls, north of Mount Baker. The lava has fabulous columns. This is a great road walk, or an even better mountain bike cruise, 7.5 miles roundtrip. No snow in sight when Doug McKeever and I went last Sunday. Highest elevation is 2400′.
