Compass Navigation - Moving Through the Backcountry

Before leaving for a backcountry trip, there are three important steps to accomplish before leaving home. First, tell someone where you are going and when to expect your return.  Second, leave a map of your planned route with that responsible person and in your vehicle. Third, fill out the trip plan I have posted on my web site at; the trip plan stays with the responsible person.  As a Search and Rescue volunteer I have learned that these key steps can make a huge difference in you having to spend an unplanned night in the woods and being found----especially if you incur an unexpected injury or loss of communication.
The following are suggestions to consider before and during a trip into the backcountry.
While compass accuracy is important, many underestimate the topographic map as a key component in backcountry navigation.  I recommend carrying a set of maps that include a 7.5’ United States Geological Survey (USGS) map and a map like a United States Forest Survey map.  The USGS map gives me the detail information of the immediate area while the other map covers a much broader area.  I look for significant land features that will surround my direction of travel.  Features such as distinct mountain peaks, a stream, and a ridge line are just of few topographic “hand rails” that can help.  For example, if a large stream is to be on your right and it’s not there, it is time to double check your navigation picture (figure 1).
