We challenge you to explore the great islands of Amaknak and Unalaska. The Geo Adventure Challenge is a great activity to enjoy with your friends and family of all ages. Register at the Community Center today and pick up your clue packet. Then start looking for the special PCR caches around town and in our parks. Earn a unique badge for every cache you find and try to collect them all. Every participant that completes the challenge will receive an exclusive 2019 Geo Adventure Prize.
