The day started with a flight from Diamond Point Airport (2WA1) with a stop at Arlington Airport (AWO) for fuel. Sometimes avgas is available at nearby Jeffco (Jefferson County International 0S9), but those folks are particularly proud of their prices, thus the run to AWO.
For this flight I flew counterclockwise around Mt. Baker, departing from Arlington Airport (AWO). My route took me northeast to just east of Concrete Muni (3W5), then northeasterly over Baker Lake. Though I'd planned to fly northbound just east of Mt. Shuksan then loop westward, I actually flew between Mt. Baker and Mt. Shuksan to get a closer view of Mt. Baker.
Once over the North Fork Nooksack River, I turned westward, flying about four miles south of and parallel to the US border, then turned southwest toward Sedro Wolley and AWO.
Clearly in view is Black Buttes, which is the arc-shaped ridge of craggy peaks just to the left of Mt. Baker's peak. These peaks are the remnant of a large stratovolcano that "stood in approximately the same location as Mount Baker, only higher. Its amphitheater shape was formed as glaciers carved out the altered core of the old volcano, while leaving the outer part of the edifice in place" (USGS, n.d.).
