Old nordmarkite quarry (nordmarkite = quartz-bearing alkali feldspar syenite).

Note:
Oftedal & Sæbø (1963, 1965) refer to this quarry by mistake as Flaen Quarry, which is another, smaller quarry. Kvamsdal (1998) has shown that the minerals they were discussing are in fact from the Kristiansen Quarry.
