Bjørlykke locality nr 24: "Located on the top of the hill Birketveitås."

Both Bjørlykke (1934) and Stensrud (2009) placed four quarries at the Birketveitåsen.

In reality there are more quarries/prospects.

Since Bjørlykke explicitly wrote "on the top", the coordinates are given for the quarry that is best visble, though it cannot be excluded that this is a post-Bjørlykke quarry.

Just north of this quarry another one is here:
58.46602°N 7.92011°Ø

And south of Birketveit 2:
58.46455°N 7.91943°Ø

There seem to be more possible prospects, but without field confirmation there is no reason to publish coordinates.

Corneliussen lists this locality as Area 5 Locality 9.

Jonny Fjermerås reported finds of titanite crystals up to 15 cm and magnetite up to 10 cm.
