Best practices for using a map and compass in the mountains?

Choosing a Map and Compass

When selecting a map and compass for mountain navigation, consider the scale of the map. A 1:24,000 or 1:50,000 scale map is typically sufficient for navigating most rugged terrain. The compass should be a baseplate compass with a sturdy design and a rotating bezel. Look for a compass with a declination adjustment, which allows you to account for the difference between magnetic north and true north.

Using the Map and Compass Together

To navigate using a map and compass, first orient the map with the compass by aligning the map’s magnetic north indicator with the compass needle. Then, use the compass to take bearings and follow the route marked on the map. Practice using the map and compass in different lighting conditions and from various angles. In the mountains, use a pacing or triangulation technique to measure distances and estimate your location.

Advanced Techniques for Mountain Navigation

In steep or rugged terrain, use a combination of map, compass, and observation to navigate. Take note of distinctive landmarks, such as rock formations or ridges, and use these to estimate your location. If you’re navigating in dense forest or heavy cloud cover, use a hand-held compass or a satellite device to get a bearing. In crevasse-prone areas, use a rope and harness to secure yourself while navigating, and always stay on snow bridges or fixed lines when available.
