I visited the petroglyphs at Bogge on the 11th of July 2023. Bogge, also known as Boggestranda, is a fairly large and diverse petroglyphs site located between Eidsvåg and Eresfjord in Molde.
While all the figures seem to be deer animals, they are draw in in different styles. The large and more realistic moose figure is thought to be the oldest, possibly carved around 4500 BCE in the Nordic Stone Age (10,000 BCE – 1800 BCE). According to the information sign, 2000 years may have passed between the earliest and latest animal figure on the panel.
The second panel at Bogge features mostly whale figures, and are estimated to be from 3000-4000 BCE.
Ship figures dominate the third panel and are estimated to be from around 500 BCE. This is at the transition between the Nordic Bronze Age (1,800 BCE – 500 BCE) and Iron Age (500 BCE – 1050 CE). This panel is so close to the current shore-line that we know it cannot be much older than 500 BCE, because the area was under water before that.
