This plot is an attempt to highlight the speculated grade. I actually hiked on some of this past the end of track as indicated in RGS XI. I have the approximate end of track highlighted on the plot. The blue line is my GPS track from the hike. I was hiking along part of the area in question and trying to decide if it was a grade. I did find some spikes along this section although that doesn't prove much. I also found lots of other debris from an old stove and other iron parts. The photo in the next post was taken somewhere along this stretch.
