It was a miracle day! I was looking for 1 1/2″ pipe at middle of forrest near Glennallen. Snow was deep as my knee and snow hidden tussock made me fall several times. Daylight was short.
I was walking around 1-2 mile random (no map with me) at the 1985 borehole site. The main porpoise of this is re measured permafrost temperature and compared with 1985 and 2009!
The way back to the read (because getting dark), I found it! Great things, I can measure it, bad news is it taking several hours to measure (already dark!).
Anyway… it was wonderful day!
