Blomstrandhalvøya caves

Blomstrandhalvøya in Kongsfjord is mainly known for the old marble mine of 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. One of them is actually accessible by boat when the sea is calm enough.
