At Gnetahallabergt, an iron ore deposit was found in the late 1730s, which later became the Inglamåla iron mine. Iron ore was mined from 1740 to 1870. However, there are also deposits of titanium and vanadium. Around 1745, a maximum of 23 miners were employed. Sometime into the 1780s, attempts were made to continue profitable mining, but 16 years later the mine was taken out of operation.

The mine then lay deserted until the mid-20th century, when the Swedish Navy chose to use the mine as a site for test blasting. In the late 1980s, unofficial attempts were made to drain the mine for geological investigation, but without further results.

To get to the water, you must first pass through an approximately 60m long tunnel. Once there, you will need a sturdy ladder and rope for the entrance. The edges consist of loose rocks and gravel which contributes to the risk of landslides and slipping. Once in the water, visibility is limited from the surface down to the maximum depth of 13m. Down on the bottom you can see the remains of iron pipes, ladders and piles, etc. The hole widens and creates overhangs on two of the sides. Visibility can quickly become zero so use a line.
