GPS and Comapss

In the last post I talked about my bushwhacking adventure on the side of Prospect Mt and the Berry Pond tract. As I said I calculated the true N bearing and followed it to the pond. I did drift a little to the west, but I hit the pond without any trouble. Now instead of figuring my heading from Barry pond to my van, I used the GPS to do that and then sighted my compass on a point that the GPS pointed at. When all was said and done I hit about 250 meters S of my car and I had to really on the GPS as I closed in. When I plotted my track on the map and looked at what I had done, my fist 100 meters were in a straight line as the woods were open, but that straight line if extended would had missed by 400 meters. That was the course set by the GPS.

Now what I think I observed was that the GPS is good at getting you to where you need to go, but you should not rely on it to set your compass bearing. I believe the GPS constantly updates and changes your course for you as you move. I noticed this when I started out for Berry Pond I check my compass sighting with the GPS and at first it was off then it settled down and was close. I will continue to use the GPS, but will set bearings independently of the GPS and rely on them when Bushwhacking. I think that is the best bet.

New Trail and Bushwhacking

I have not really been an outdoorsmen lately as work has taken a lot of my time. Finally, the catering events and major functions are over for a while and I am ready for some of doors fun. I did do a little catfishin' last week. Did ok, of course the big one got away...no really it did :-)

Yesterday I went geocaching at the Lake George Rec Park where I had been before. There was a new set of GC's planted that took me up to the summit of Prospect Mountain. A approach that I have never done. Also I looked for and found my first Hybrid Cache/letterbox. I would like to see letterboxers not be so adverse to the idea of using GPS coordinates in their clues, but at this time many letterboxers have a negative view towards this. I digress...

Anyway these geocaches where placed about 350 meters apart (Yes I said meters I am on a personal quest to go metric. And I was born and raised in the US) which I think are too close, however this placer hid the caches at strategic points that brought me up the mountain perfectly. The geocacher actually says that that is why they were placed there.

After learning the new trail, at the last Geocahe, I calculated my bearing and bushwhacked to Berry Pond a new acquisition by the Lake George Land Conservancy. I did pretty good for a 2.3 km hike through the bush. I hit the pond at about where I was trying to get to. I then, being lazy took a direction with the GPS and followed that bearing out to my car.

I will talk about that later this week. All and all a good day and I was able to work on my land navigation skills a bit.
