Writing at 90 degrees on the compass
Find the degree mark that points the way you're facing, and add up the degrees between this mark and the nearest of the eight directions; that's your orientation.
Reliable Weather Indicators "Red at night, campers delight; red in morning campers warning.
Remember to decline North first and then find midpoints, so you don't have to decline all eight directions. The website also tells you by how much declination is changing per year. Tips The end of the needle that points North should be colored red, so make sure that the red tip rests on North when reading your compass.
Read this as 5 degrees West-Southwest. Two of its main uses are to measure bearings, and to pinpoint locations. You see, the closer you get to the magnetic north pole located near Bathurst Island in Northern Canada inthe more the north-seeking end of the needle is pulled downward.

Writing at 90 degrees on the compass
Hiking, Mountaineering Introduction The basics of compass usage are surprisingly simple and can be mastered quickly; and once learned they will certainly become an invaluable skill for any hiker, mountaineer, back country skier or suchlike outdoor enthusiast. Figure 4 above has magnetic north lines drawn on it, and thus no adjustment were needed to use the map bearing in the field. Figure 1: The Parts of an Orienteering Compass. Now plot this line back to the position line in this case the hiking trail you are known to be on, and where the line crosses the position line is your exact location. But, for finding your way or locating destinations in the wild, use degrees as you'll see in a bit. Roughly the distance to the North Star from the Big Dipper is 5. Knowing where true north lies, now follow the declination adjustment rule by subtracting 20 east declination degrees from your degree bearing and set your compass dial to degrees. Also always remember that a GPS unit is a delicate, battery powered device that can fail or be easily damaged. Next you adjust it for, say, the 10 degree easterly declination of the area arriving at a map bearing of degrees - remember to convert a field bearing to a map bearing do the opposite conversion of a map bearing to a field bearing by adding east declination and subtracting west declination. On the other hand, if you were to miss your car by being to the south you would cross the road, and you could just follow it back to the car. If is set to the correct time, simply point the hour hand at the sun, and in that position, the point halfway between the current hour and the 12, is south. A compass trick used to avoid declination adjustments is to place a piece of scotch tape over the compass dial starting at the east declination and ending at the value of declination plus Wristwatch as Compass: A watch with an hour hand can be used as a makeshift compass. There are four cardinal points on a compass - North, South, East, and West.
Now, read the bearing at the compasses index line, and follow the bearing in the field! Find the remaining directions by finding the midpoints between each amount. Does it flow east, or northwest?

The magnetic needles north end is painted red and its south end white. A word of caution, map bearings and field bearings can differ in the USA by as much as 30 degrees east and 20 degrees west. Know the scale of your map. Say you want to travel to a large rock outcropping on the horizon, which is currently visible to you, but which may leave your field of vision when you walk into a dip, or when pending clouds come in or the sun sets. Navigation Tips and Tricks Understanding Maps: To be truly strong at orienteering and navigation, one must become very familiar with maps, and the abundance of information they contain. Pale Yellow sky at sunset indicates wet weather. Declination is given in degrees, so this gives you one more good reason to learn how degrees work. We say areas to the left of the line have east declination and those to the right have west declination. Stop, add degrees to your initial bearing, pick out a landmark along that bearing and walk another 15 steps toward it, stop and once again increase your bearing by , pick out a third landmark and again walk 15 steps. So that is why you subtract east declination. We could add additional points, continueing to break each section in half over and over, but telling someone to go East-EastEastNorthEast-EastNorthEast would not be fun. Wait minutes, as the shadow moves from west to east the opposite side the sun moves on, ie the sun moves from the east to the west -- but both the shadow and the sun move in a clockwise direction. Whichever end of the needle points towards the sun is South and the end that points at you is North.
On the USGS maps you will see markings for both grids.
