- Collecting Features
Identifiable things or places you pass. Locating them on a map (or "collecting" the features) helps to tell where you are. Example: "Head west until you hit the trail and then turn right."
By identifying the terrain and features as you go you will know when you are coming close to your target, often a trail, or when you are drifting off course. Example: Following a compass bearing, break one long section into several short sections between identifiable features, even if you have to zig-zag a bit.
It often is faster and more accurate to follow compass bearings short distances from one distinct feature to another than to go in one long, straight shot on a single bearing.
