N19K (AEC)

Station Notes

Adopted by the AEC
A rock wind wall is mounded around the sensor well cap box, but not in contact with the box. No material was available for burying the well cap box.
The site is on a plateau below the main peak and the NPS repeater hut at the apex of the hill.
The site is high and in a location that likely remains mostly snow free due to wind scouring
