18. For our photo session, we went to Cajon Pass, which has a lot of natural features and a lot of human infrastructure. It's also enveloped by the San Bernardino National Forest. Our USFS map didn't show the magnetic declination, but it's 13 degrees east. As such, we oriented our map by setting the compass bezel 13 degrees east, and the edge of our compass along the north-south indicator lines on the map. When we turned the map and the compass so that the needle and the yellow line matched, our map was oriented. Now that the map is oriented, we can take directional bearings without worrying about the declination again because the readings will be correct relative to each other.
