Blomstrandhalvøya caves

Blomstrandhalvøya in Kongsfjord is mainly known for the old marble mine Marle Island / Ny London and the beautiful scenery, but it has also some geomorphological regional rarities in shape of several caves. The bedrock consists of weakly metamorphic carbonates (“marble”) which has many small geological faults (cracks). Water could easily attack along these faults, mainly chemically by solution but also mechanically, especially subglacially during the Pleistocene when meltwater would run off at the bottom at the glacier under high pressure.

Some of these caves are more or less inaccessible, while others are easy to get to.

This small cave is a bit higher up on the slope:

This large cave is quite steep and the roof is partly gone:

This small but beautiful cave is situated directly on the coastline:

One of the caves, the “grotto”, is actually accessible by boat when the sea is calm enough. You can visit the Blomstrandhalvøya grotto on a separate page (click here).
