There is a small site with petroglyphs at Åskollen in Drammen, located within walking distance from the petroglyphs at Skogerveien. The main figure is a large moose with intricate internal patterns. There are also supposed to be two smaller more abstract figures. The figures are dated to around 4500 BCE during the Nordic Stone Age.
The paint once applied to make the figures visible had faded at the time of my visit. Which is a shame, since it is obvious from what is still visible of the moose, that this is a beautifully carved figure.
