GROUND RULES by cl i f f jacobson Get Your Bearings Quiz: How well do you know how to use a map and compass?


4 If you make a 10-degree compass error over a 1-mile distance, you will probably miss your objective by about: a) 10 feet b) 100 feet c) 1,000 feet d) 10,000 feet


5 You are on Pikitigushi Lake (see map) and want to canoe the creek down to the lake at E. If you enter the creek and paddle south, you will: a) Paddle downstream, with the current. b) Paddle upstream, against the current. c) There is no current in the stream. d) The current reverses approximately halfway down the creek.


EVERY FIRST CLASS SCOUT can compute a bearing from a map and follow it on the ground. But can he correct his compass for magnetic declination? Triangulate his position on a map? Interpret topographic dangers like falls and canyons? Take this quiz and see how much you


and your Scouts know about wilderness navigation. You’ll need a compass and pencil to do some of the problems. Note: An incorrect question on a camping quiz is no big deal; one wrong compass bearing, however, will get you lost! Choose the best answer. Some ques- tions have more than one right answer.


1 These three “norths” are always indicated on a topographic map: a) True, magnetic, grid b) True, geographic, magnetic c) True, geographic, cartographic

2 You have computed a “true” map bearing of 90 degrees to your objec- tive. The magnetic declination is 10 degrees east. What bearing should you set on your compass dial? a) 90 degrees b) 80 degrees c) 100 degrees d) The declination value doesn’t matter.


3 The “contour interval” is given in the margin of every topographic map. It tells you: a) The horizontal distance (in feet or meters) between contour lines b) The elevation of the contour lines c) The vertical distance (in feet or meters) between contour lines d) When the contour lines were last updated


6 The contour interval on the Pikitigushi Lake map is 50 feet. What is the approximate elevation of Point A? Tip: Note the 1,000-foot contour line to the east. a) 1,000 feet b) 1,050 feet c) 1,150 feet d) 1,250 feet


7 You are canoeing on a lake. Your objective is a campsite on the far shore 1 mile away. The campsite is partially obscured by trees and can’t be seen from far away. The best plan is to: a) Compute a bearing to the campsite and follow the bearing. You should arrive on target. b) Compute a bearing to an imagi- nary point on the shore that’s a few hundred yards to the left of the camp-
