This Wherigo will take you on a High Seas Adventure around part of the Shadow Mountain Lake in Grand County, CO. If you successfully complete your voyage, you will be directed to the sunken treasure (a physical cache container).
Your voyage will take you about two miles around a portion of the lake. Figure on boating between 3.5 and 4 miles total with about 2 miles of that being the actual play of the Wherigo. If you use a boat with an engine or a motor, you will be able to complete the Wherigo quicker than a canoe or a kayak, but larger boats may have a harder time getting all the way to the final. You may need to get out of the boat to retrieve the cache container at the final. This is a 5/5 cache after all! Download the Wherigo Cartridge by clicking the "Related Web Page" link at the top of this page. Fully tested on iOS and the Wherigo player that is built into some GPS receivers. Will also work on Android. Some minor features do not appear on the GPS receiver players, but it does not significantly affect the game play. For best results, make sure you turn your sounds on and all the volume all the way up on your device. There should be a "ding" or a noise for every set of new messages that you receive. You will be on the water the entire time. You may want to consider placing your smart phone or GPS device in a ziploc bag to protect it from getting wet.
