Cache in on fun

MAT-SU — The combination of satellite positioning and global communication means scavenger hunting is no longer limited to 7-year-olds’ birthday parties and fraternity pledge pranks.

The basic premise of geocaching is simple. One person places an object — an ammo can, for example — and records the GPS coordinates to www.geocaching.com. Other hunters then search for caches in their area using these coordinates and record their finds to the site.

Geocaching gives participants of all ages an opportunity to visit places they might normally not go and a sense of accomplishment once there, GPS-enthusiast Robin Braaten said. Having started just this fall, Braaten proudly said she has already recorded more than 90 finds.

While it sounds simple, the task can become more complex as most GPS units are only accurate to within a 15-foot radius. Sometimes the cache will be easily visible, and sometimes there will be hints on the website. But descriptions can also be vague, caches can be covered in snow, and cloud cover can reduce the sensitivity of the GPS unit, Braaten said.

The activity is great for families or solos, and it’s a great way to get outside in the winter, Braaten said. Cache hunters can use any GPS unit, but some units are able to attach to computers and download coordinates and instructions directly.

Caches can be at a park bench in downtown Wasilla or a remote spot of Hatcher Pass. Some will be on private property as indicated on the website, but hunters should only go on private property when they are sure they are in the right place and have permission, Braaten said.

The activity is truly grassroots, Braaten said. Anyone can upload new locations, and there are locations literally all across the globe.

A basic knowledge of GPS skills is necessary for the activity, and Braaten is offering free classes for beginners interested in starting out. The class is this Sunday starting at the office Expedition Log Homes at Mile 49.8 of the Parks Highway. The class starts at noon, and the first hour and a half will be dedicated to beginners with no experience using GPS units. At 1:30 p.m., new and experienced hunters alike will hit the caches with a chili feed to follow.

Space in the class is limited, so preregistration is required. Call Braaten at 240-4742 to reserve a spot or for more information.
