"Orienteerers never get lost.....they just lose map contact"
Translation, You must read the Topo/Map, know how to use the compass and be aware of where you are "on the map" at all times. Orienteering teaches "thumbing" the map. You fold the map and use the tip of the compass to "point' on the map, exactly where you are. "I'm at the point on the map where the bridge crosses the river'. Walk a bit, note that you are now where the trail is climbing the hill and you are at the top, move the pointer to the trail shown on the Topo at the top of the hill. Maintaining contact with the surroundings and the map at the same time.
