At the bottom of Vargavågen on Halhjem lies Grødalshaug, a 30 metres high rocky outcrop between the bay and a moist valley cleft. On the south side of the rock is a steep rock cliff facing the valley, the bog and the stream. On this rock face we find rock carvings from the Bronze Age.
Steatite is a type of stone that is abundant in Hardanger. There are large steatite deposits in the mountain below Folgefonna. These deposits are visible both in Krossdalen in Jondal, at Kveitno in Odda and at Måge in Ullensvang. There are many traces of steatite quarrying in Hardanger, and one of the largest fields is in the hillside above Måge.
