At these latitudes the late December sun never gets very high in the sky. This picture was taken near Lillypad pond at about 1:00 pm. |
As mentioned, I've hiked in the PLW before and this was a favorite destination for family hikes when our children were children. In fact it was at Pharaoh Lake, nearing the end of an epic, six day, family backpacking trip that our nine year old daughter uttered one of the most memorable lines in our family history;
"We've been here for a week, we are out of food, and our parents don't care."
We were getting low on food and she and her brother were sick of our freeze-dried fare. She used that line to extract granola bars from passing day hikers. Once Elle and I caught on we had to put a stop to her "gathering" activities. But I have to admit, we were all pretty sick of backpacker food at that point and I was tempted to let her keep trying.

The map image shows my GPS track (light blue) overlaid on a trails layer (orange) that can be download from the New York State DEC website (displayed using Google Earth). I was curious why the GPS track is not more closely aligned with the trails from the DEC map layer. I would expect the GPS track to be accurate to around 30 feet. But the gap between my track, and the trails map layer route, are separated in places by as much as a quarter mile.
There are several potential sources for this type of discrepancy. One is that trails are commonly re-routed. A closer look at the start of the route (below) shows an example of this. It used to be that there was no parking at the trailhead for this route. There was a parking area .3 miles away but you walked along Route 74 to reach the start of the trail. Route 74 is a busy road, so a few years back DEC added a bypass trail through the woods. The map below shows that the DEC trails layer has not been updated to include this new section. The GPS track shows the highway bypass but the trails layer shows the route starting at the old entry point on the highway.
This provides a clue as to the source of the discrepancies between the GPS track and the trails layer route. It may simply be that the trail maps for the PLW have not been updated in some time. If those routes were drawn pre-GPS they were probably hand-drawn on a background map. That approach results in a lower accuracy.
