pre-determined route, where they are given the bearings and distances to Way Points / Control Stations. At 08:45, we started them individually, and staged every 10 minutes, to orienteer a simple route around the perimeter roads of Windsor House and through the farm to the back yard (Annex 3). After they completed the route, about 10:00, S. Stewart gave a brief lecture on triangulation and then we returned to the yard to practice triangulating to the dominant landscape features surrounding Windsor House. At 11:30, we moved the class to the Troy-Windsor trailhead to practice pacing 100 meters on (1) a trail with a gradual incline — the main trail and (2) a winding trail with, short vertical assents/descents — the trail to Windsor Great Cave. We discussed how you count your paces in a vertical ascent when no distance is gained.
We returned to Windsor House at 12:30 for lunch. Mike has the computer projector working for afternoon lecture! 13:30 S. Koenig begins lecture by having DS and AF read the descriptions they recorded for the Way Points from the morning's orienteering exercise — very good attention to details. S. Stewart then lectured on map alignment (aligning map to grid north) and compass alignment (using the meridian lines on the compass). Important lesson learned about compasses and magnetic interference: the tables we are using have wooden tops but metal legs. The metal table struts visible affect the compass needle. M. Schwartz then lectures on the principals of contour lines, using the CD rom as a teaching aid. He used a yam, sliced in 2 cm "layers", to demonstrate the principal of converting a 3-dimensional landscape feature to a 2-dimensional topographic map by having participants trace the outline of the yam segments on paper. After lecture, we spent an hour walking along the back-road of Windsor to identify features of the landscape (isolated hills, cliff, saddle corridor, polje) and match these features to the topographic maps participants carried in the field. 27th November, Wednesday We had two hours in the morning before the arrival of Red Cross. R. Stewart lectured briefly on the distinction between line orienteering and route orienteering. Three participants were late for morning lecture and instructed to ask their colleagues for notes as the instructors do not repeat lectures for those who are tardy. After the brief lecture, we walked along the dirt road to the trailhead of Troy-Windsor Trail. Participants used compasses to sight bearings as they walked the road, paced their distances, and marked their stations on maps. Finally, we took them back along the trail to the lower opening of Windsor Great Cave for a measured-pacing exercise on a steep slope (e.g. approx. 50 deg that leads to the upper opening of the cave. They have now measured their paces for 100 m along terrains varying from level through fairly steep. We returned to Windsor House at 10:30, where Ms. Edna Facey of the Jamaica Red Cross — St. James Branch had recently arrived. For the rest of the day, she lectured on emergency first aid. R. Stewart and S. Koenig spent the rest of the day setting the Guthrie Trail route for tomorrow's practical examination. In the evening, S. Koenig gave everyone a copy of the instructions for the route so they could prepare with their maps as they felt necessary. Koenig - Orienteering Dec 02 13
