The Holtemme is a 47 km long, orographically left and southwestern tributary of the Bode in the Harz and Börde districts in Saxony-Anhalt (Germany). The name Holtemme is a combination of the word stems Holt (Old Norse for forested hill or originally for a wood) and Emme, which, like the river of the same name, probably goes back to the Gallic-Celtic word ambis (= river, Latin amnis). The etymology shows that alternatives for the former are also Holle (hill, elevation) or Holz (from the Germanic Holta(z)). Albrecht Greule, on the other hand, assumes that the second part of the name is an n-derivation of the Germanic word stem *ami- (= natural watercourse, Amina). (Source: Wikipedia)

This is a very old mining attempt that ends after just a few meters. A small quartz vein without visible mineralization was examined.

I had no desire to crawl in there; from what I could see, it was quite a steep drop. 😉 But it did have a certain mystical quality.
