The Mapsurfer letterboxes are a diverse series of challenges for the beginning and experienced letterboxer alike, although they are geared more towards the veteran letterboxer or armchair treasure hunter looking for more than a simple hike. Cryptic treasure hunts and riddles, geography puzzles, and spectacular hikes and drives through history and wilderness will keep you on your toes. Every Mapsurfer letterbox has its sequential box number carved into the stamp image in some form.
Lets be blunt.
Some of them are hard. You may also need to use various tools and techniques both in the field and before setting out in order to crack the harder ones. Each box has a challenge rating from 1 to 5 stars. Those rated above 2 stars are not generally recommended for the easily disappointed or the beginning letterboxer.
