Present Objectives

Present a topo map of a day hike area that the students aren't likely to know.

Describe a travel problem for which a trail is not shown on the map.

Ask students to describe possible routes.


 * How terrain features affect travel route.
 * climbing spines/ridge lines
 * often easiest as more open, things fall away to either side
 * climbing draws
 * often choked
 * sometimes washed clear
 * traversing side hills
 * difficult keeping your footing
 * inferring underbrush
 * moisture, streams makes thicker

''Choose one of the proposed routes. Break trip into segments of bearings and distance. Record as a set of instructions.''

Estimating time:


 * 1000 ft elevation gain = 1 hr
 * elevation loss = no penalty


 * 3-5 km/hr horizontally on trail
 * slower if thicker bush

Estimate time of this trip.

Aids

 * 82G/8 for each pair of students
 * plenty of table space
 * a compass for each pair of students
 * pencil for each student
 * map quality eraser for each pair
