Memorize the terrain

When moving cross country on foot stop every few minutes and take a long look at your back trail. Try to memorize the terrain. Wild country always looks different from different angles.
If you have to back track this will help you retrace you steps. I don't like to blaze a tree, but if you absolutely have to, be sure you make a mark that identifies your direction and can be seen going both ways.
