The newer route left Sabbath Day Pond LT and went over more mountains. I was behind my goal of hiking miles, partly because I left later in the morning. But at this point of the trip, I needed 10 hours of sleep to recover.
Here is the map of the southern route leaving west from the LT:
and now the same area from a newer USGS map showing the current route:
Isn't the USGS TopoView map really cool?
