Accurate Compass Readings

I found these recommendations a while back when I was researching techniques for using a magnetic compass.  A small error when using a compass can result in significant error in measurement on the ground.

To obtain accurate readings when using a compass:

• Ensure the compass has been adjusted for declination. 
• Hold the compass level and steady so the needle swings freely.
• Hold the compass about waist high in front of the body, except when using a compass with a sighting mirror or a sighting type compass.
• Raise and lower eyes when taking a bearing, do not move your head. Always use the same eye when taking bearings.
• Directly face the object that is being measured.
• Magnetic fields will give incorrect compass readings. Avoid taking readings near magnetic fields such as steel, iron (ferrous metals), vehicles, rebar, and clipboards. Even belt buckles, glasses, and rings can interfere with the compass reading.
• Take bearings twice. 
• Adjust for magnetic declination as appropriate.
• Follow the direction of travel arrow, not the compass needle, when walking a bearing. Always follow the line indicated by the compass rather than relying on judgment as to the direction.
• Use back bearings to ensure you are on track when navigating.
  

  
• Compare compass reading with those of your GPS.
• Remember that a GPS receiver's compass must be calibrated after every battery change.

Escape or Shelter In Place

A few years ago I wrote a short post about Planing  Your Escape Route.  I recommended that when evaluating an escape route I suggested that the hiker consider several elements. 

First, take a look at your topographic map and tail guides to determine potential escape routes.  Evaluate the terrain.  Are there barriers due to slope and vegetation?  This is especially true should the hiker need to “bush whack” cross country.  A conversation with a ranger can be invaluable.

Right now my home state of Oregon is ablaze with wild fires.  Fires are everywhere.  Here is an overview of all the fires as of 8/30/2017.

Just recently over 100 hikers found them selves stranded as fire closed their trail and were trapped between blazes.  They have been rescued, they survived and they are lucky.
