Once you are ready to redeem your prize, you can still enter this information into your Passport Book, but you will just need to immediately print it off because you can't save it.
  4. For the convenience of our geocachers across Idaho, our 20 total geocache locations will be grouped together in each of our 4 BLM districts - Boise (Southwest), Coeur d'Alene (North), Idaho Falls (East) and Twin Falls (South Central). Pay attention to each of our cache names on the geocaching.com website to learn where each cache is located. Just choose the region closest to your home and start collecting!  Each district hosts 5 cache boxes (4 specific district caches and 1 state cache).  Once you have located 4 caches for a specific district, you will earn a prize.  Cachers can choose between a flier frisbee or a pin. For our explorers interested in traveling the state - If you locate 1 box in each district from our statewide list (4 total), you will be eligible for the state prize. These cache boxes will be listed specifically as our "State" boxes on the geocaching.com website.
  5. After visiting each BLM geocache destination, you will be awarded with a specific electronic stamp for your location. 
  6. Save each electronic stamp to your computer.
  7. When you're ready to add your stamps to your passport book, just open your saved passport book and click each box to keep track of your progress. Please check out our example passport if you need further clarification. Don't forget to re-save your updated passport book each time you add a new stamp. Please Note: If you have have Adobe Reader, you won't be able to save your document with the stamps in your Passport Book.
