Geocache Description:


Hi Johnny Chase Cache here again.


You helped me find some of these caches in the West Island (GC14RE5, GC17W6T, GC1229N, & GC121BD) and now I need your help again.


I went to hide a cache. I started exactly at the co-ordinates given but then my GPSr died. I had no spare batteries but I was prepared for that. In my backpack I had all I needed to place the cache - a watch, a compass, and a traverse board.

What is a traverse board? Think of it as an old fashioned sailing equivalent to the track log on a modern day GPSr.

The traverse board first appeared around the time Christopher Columbus sailed the oceans and was used up to the end of 19th century when more sophisticated navigational methods were invented.


On a sailing ship the traverse board was placed directly behind the helmsman. The ship's day began at noon and was divided into four-hour periods called watches. During each watch, a seaman recorded the ship's direction and speed on the traverse board by placing pegs in the appropriate holes. The compass showed the direction and the chip-log, a weighted board attached to a line, was used to determine the speed. At the end of the watch either the master or navigator recorded the information on the traverse board in the ship's log, then removed the pegs so the next watch could collect the data all over again.


For geocaching I placed a peg every five minutes that I walked starting from the inner circle. Luckily for me I am fairly good at judging my walking speed down to half a knot (this is a marine device after all!). I placed a peg for my speed every five minutes starting at the upper left row.


Below you will find the result of my walk. Keep in mind that I stayed on a sidewalk or path the whole time except for the last leg when I hid the cache and even then I never went more than 150m off the path. I also did a lot of zigzagging in the woods when placing the cache.

I realize this method does not have the precision of a GPSr but it should be accurate enough to locate the cache if you work with a map and make some minor adjustments as you go along.


Can you help me find the cache?
