>>1609608It’s called Route Sketching. Kephart has a whole chapter in his book on it. I dumped the pages here a couple of years ago and will do again if any anons are interested. Basically you figure out how many double paces it takes for you to do 100m or yards. After that with a compass you just shoot a bearing and count places towards it. Record it in a book. It’s one of my favourite things to do while /out/. Pic is my stuff.
