Foot bridge over the Middle Fork
Ridley Creek Trail begins at the end of the Middle Fork Nooksack Road on the southwest flank of Mount Baker. The trail accesses the heather meadows of Mazama Park and on to Park Butte Lookout. Along the way see forested latest Pleistocene moraines, glacial till from Canada complete with quartzite pebbles from the Rocky Mountains, limestone, lahar and ash deposits, a close up of the Cathedral Crag lava that predates Mount Baker, and finally, great views of Baker, the Black Buttes, and that enigmatic slice of the mantle, the Twin Sisters Range. Read the geology guide here. Enjoy!
