Relatively large quarry described by Stensrud (2009).

He writes that there was an old, partly collapsed quarry, and that later two horizontal shafts were blasted into the pegmatite.

The coordinates are based on the LiDAR map only.

And since there are two other potential quarries nearby, field inspection is necessary to confirm this quarry.
