Map and Compass Skills
This program may be scheduled for groups whose members are 12 years of age and older and requires at least 2 weeks of advance notification limited to center staff and volunteer availability. Participants in this program must be able to tolerate short walking distances on sandy substrate in the climate typically represented in the time of year you book your program. The length of this program is 2 hours.
Navigation using a compass used to be essential for explorers. Today modern GPS devices tend to take the place of old-fashioned or traditional map and compass reading. Participants in this program will learn to read topographical and physical feature of a map, set a compass heading and pace out a distance. Once everyone is familiar with the compasses they will have an opportunity to test their skill on a navigation course.
