ABC Method • A-Align your compass on the map so that the long edge of the base is on a line from your present location to the desired destination. • B-Bearings are found by holding the compass steady and rotating the dial (azimuth) so that the “N” on the azimuth is pointed north on the map. • C-Courses are followed by picking up the compass and holding it in a horizontal position so that the magnetic needle is free to rotate. Pivot yourself until the orienteering arrow is aligned with the magnetic needle. The compass now points in the direction you need to travel to reach your desired destination. • https: //www. youtube. com/watch? v=NBhd. I 4 s. JWVY

Following a Bearing • Leapfrogging: -Repeatedly identifying an object in the near distance or positioning a person in the near distance to maintain the proper bearing while navigating over a longer distance. -To leapfrog with a partner, one person goes in the desired direction to a distance of 20 -30 meters. -Instruct the partner to move until aligned with the direction-of-travel arrow.

Components of a Topographic Map • Legend: A chart on the map that identifies the meaning of symbols. • Map scale: Ratio of distance on a map to a distance in the real world; topographic maps are commonly 1: 50, 000, which means that 1 centimeter (. 4 inch) on a map equals 50, 000 centimeters (19, 685 inches)in the real world. • Colors on Maps Blue: water Green: forested areas or vegetation White: open barren or grassy areas https: //www. bing. com/videos/search? q= reading+contour+lines&&view=detail&mi d=359 D 87166120 F 598873 C 359 D 8716612 0 F 598873 C&&FORM=VRDGAR&ru=%2 Fvi deos%2 Fsearch%3 Fq%3 Dreading%2 Bcont our%2 Blines%26 FORM%3 DVDVVXX • https: //www. bing. com/videos/search? q= explain+declination&&view=detail&mid= 43 A 6413 A 3 C 98 B 73 ADA 9343 A 6413 A 3 C 98 B 73 ADA 93&&FORM=VRDGAR&ru=%2 Fvi deos%2 Fsearch%3 Fq%3 Dexplain%2 Bdecli nation%26 FORM%3 DHDRSC 3 • •

Treasure Hunt Project • In Groups of 4 • Using Cardinal Directions, bearings and paces only, create a series of directions that has a defined start and finish. • Starting Point must be a bearing • -ex: Start: Band Tower is bearing 102 degrees. The entrance gate to the football stadium is bearing 208 degrees. • Use the compass on your phone • -Minimum of 10 directions; max of 15 • Treasure could be any of the following: • Door (No bathroom doors/hallways) • Snack Machine • Mat/Rug • Poster • Water fountain • Locker • clock • • EXAMPLE: Start facing the door to room 1115 Face 325 NW degrees and walk 10 paces Face 50 NE degrees and walk 5 paces Face 40 NE degrees and walk 20 paces Face 350 N degrees and walk 5 paces YOUR TREASURE IS 324 DEGREES NW WHAT AM I?
