Stensrud (2009) describes this quarry as being located in the middle of the farm ground at Midtre Frikstad, directly west of the farmhouses.
Unfortunately, he forgot to mark this locality on his map. The problem is that a map search and a Google search (Febr. 2018) for Midtre Frikstad didn't result in anything useful. Most likely he meant the Rogdevollen farm owned by the Frøysa brothers, who also are the owners of Slobrekka and Tuftane.
But actually the altitude map shows a small prospect directly W of the farmhouse, so that is then a likely candidate.
