Vertical veins, 2 to 25 m wide and up to 2 meters long, cutting hydrothermally altered basalt (Tschernich 1992). On the northern side of the Hvalfjördur and thus in the Western Region, south of the old whaling station.
According to Weisberger & Selbekk (2009) epistilbite is found only here in the Hvalfjördur area.

Erronously spelled as Hvalstod in Robinson (1986): 340.
Erronously spelled as Hvalsgod in Tschernich (1992): 524.
