Around here we do more navigating based on nearby visible landmarks than by compass triangulation from long-distance landmarks - roads, trails, lakes, rivers, etc... Wetlands' margins are too undefined to be of much use for that. Sometimes I can key in on a large antenna(s) if on the topo map, but they often aren't. Antennas and water towers could be real valuable landmarks if on maps, but they go up so fast it is often hard for the maps to keep them up-to-date.

This is why a GPS and UTM coordinates/grids are sooo valuable around here.
