    Thanks for the reminder, as I usually have a compass and map of the area.

    Thought I'd add the following if there wasn't any sun or a heavy canopy preventing sun from getting through.

    Also would like to note as far as using clouds for navigation it can be hard with a heavy canopy above and a dark gray cloud cover like it is in the NW. It can be hard to distinguish the direction clouds are moving unless you can find a clearing and get out from under a heavy canopy.


    Finding Direction Without a Compass

    Finding Direction Without A Compass and Time without a Watch

    Hiking in remote areas is a great experience if approached with due regard for fitness, safety and skill. An important skill is the ability to navigate with or without compass and map. Ideally, no one should ever head off the beaten track without map or compass, but what if you lose or damage your compass? Here are a few basic skills that could one day be of use.

    Finding direction by using your watch...
    If you have a watch that is set to local time, you can always quickly determine the approximate points of the compass as long as the position of the sun is visible. The method used varies depending upon which hemisphere (northern or southern) that you happen to be living in. The following methods are described using an analog watch, (that's a watch with an hour and a minute hand) but they can be applied just as well if you own a digital watch. Just use your imagination to superimpose the 12 hourly numerals and the relevant position of the "hour hand" on the face of your digital watch. If your watch happens to be adjusted for daylight saving at the time, then remove the daylight saving for greater accuracy. This method will give you a good approximation of true north or south but is not intended as a substitute for the accuracy of a compass and the closer you are to the Equator, the less accurate.

    Northern Hemisphere
    Holding your watch horizontally, point the hour hand of your watch at the sun. Note the direction that lies exactly midway between the hour hand and the numeral twelve on your watch. This will be South on a north/south line. If there is any doubt as to which end of the line is north, remember that the sun rises in the east, sets in the west, and is due south at noon. The sun is in the east before noon and in the west after noon. Once you have established this, it will be easy to determine the other points of the compass.

    Southern Hemisphere
    Holding your watch horizontally, point the numeral twelve on your watch at the sun. Note the direction that lies exactly midway between the twelve and the hour hand. This will be North on a north/south line. If there is any doubt as to which end of the line is north, remember that the sun rises in the east, sets in the west, and is due north at noon. The sun is in the east before noon and in the west after noon.

    These methods will give you a good approximation of true north or south.

    Another method of determining compass points can be used if you do not have a watch. This method takes longer and requires enough sunlight to cast a shadow...

    To find North without a watch
    Before noon, on level terrain, position a stick of about 3ft upright into the ground. Mark the tip of its shadow with a peg or stone. Using the tip of the shadow as a radius, draw an arc around the stick. The shadow will shorten as it approaches noon, pulling back from the arc. It will then lengthen again - where the afternoon shadow once again touches the arc, place another peg or stone. Now draw a straight line between the two pegs/stones - this will be an East/West line, with the first peg being in the westerly direction. You can now draw a North/South line at right angles to the East/West line.

    The following (less accurate) method can also be used at any time of the day without drawing an arc...Peg the tip of the first shadow, then about 20min later peg the tip of the moved shadow. Draw a straight line between the two pegs, and this will be an approximately East/West line, with the first peg again being the westerly one.

    Telling the time without a watch...
    Determine North, South, East and West using the method previously described. Position your stick at the intersection point of your East/West, North/South lines. The Eastern point of the arc around the stick will be 1800hrs, the Western point will be 0600hrs, whilst the Northern or Southern (depending on which hemisphere you are in) midpoint of the arc will be 1200hrs. The approximate time of day can then be read off the arc using the moving shadow.

    A typical error when lost, is a tendency to wander off what you may think is a straight line bearing, sometimes even slowly circling back on yourself. To prevent this, note an object (tree, rock, feature) that lies directly ahead of you in the direction you wish to travel, then aim for it. When you reach it, take another bearing on the direction you wish to head and sight another object directly ahead of you repeating the process. In areas of restricted distance visibility, you may have to repeat this quite often over short "legs" to ensure that you are remaining on course.

    Keeping a course by the clouds...
    What if it's a cloudy day with no sun visible to get a bearing on or the bush canopy prevents you getting a clear "shot" at the sun? If you are lucky, it may be windy with the clouds moving in a constant direction - note the directional flow of the clouds and adjust your course relevant to their direction. e.g., If the clouds are moving from your front from right to left over your shoulders, keep them there, at the same time, sight an object straight ahead of you and head for it. To retrace your steps in the same general direction, just do an about turn, then keep the clouds moving from behind and now left to right over your shoulders and repeat the process.

    As an example of "cloud navigation", when moving inland through dense bush away from a coastal beach, it was realized that it was not immediately evident in which direction the coast now lay. Before entering the treeline, it was noted that the clouds were moving in a direct line from the trees to the coastline. It was then just a matter of looking up and following the direction of the clouds to enable a heading in the correct general direction and once again access the beach. Being aware of your surroundings will often pay off, so it's a good habit to try and cultivate.
