Cool, I just realized that 90% of my nav in the woods is done by terrain association. The compass is really used just to orient the map, and myself.

Although I've practiced it quite a bit, I've hardly ever actually used classic straight-line travel along a compass heading to get from point A to point B.

I have used resection/triangulation more often, but usually using one landmark in combination with the terrain feature that I was standing on (ie bearing to landmark intersecting with a ridgeline).
