The cache is not at the listed coordinates but is a short walk away.
You will need to bring your own pen.
The cache can be found at:
S 1F° 37.2E0 E 73° 36.2B0
The cache is a dark green nano that is placed up high but there is a something to climb onto to retrieve. You may need a mirror tool or be willing to feel for it.
Congratulations to .K.B. for being FTF
