It is an interesting time to be talking about navigation. Recent news articles have said that the magnetic North Pole is moving. They say it is headed for Siberia. It will undoubtedly take a long time to determine that it has stopped at a fixed point. Then USGS needs to determine the impact on the declination angle (the difference between magnetic and true north). Once that is done, they must print new maps to show the corrected declination. For those of us who us GPS, it is not as important because GPS uses true north as opposed to magnetic north. If you are still using the compass…stand by…things change.
That is NOT to say that you can ignore your map and rely exclusively on a GPS. Battery operated instruments have a nasty habit of running out of power at the least opportune times. Every adventure into the wilderness (including Pikes Peak) ought to include a map of the intended area. Look closely and carefully at your intended objective before you set out. Note the route, terrain, obstacles, potential hazards. alternative trails and emergency egress routes. Determine the elevation gained and lost for your route. Estimate the distances and trail difficulty and the time you expected return to the trailhead. While on the trail, correlate your position with known points. Know where you are relative to significant points along your intended route. Look back along the trail at those significant points to have some familiarity with the return route. Leave your trail information with someone who is not going with you in case they have to call Search and Rescue.
