35. Wallenborn: A cold geyser
The 'Wallender Born' geyser came into being by accident during drilling operations in 1933. During those operations - with the aim of making profitable use of underground reservoirs of carbonic acid - the workers discovered a gas-filled chamber. Ever since then, the gas has shot up to the surface under high pressure, taking water with it.
This leads to an eruption of the geyser every half-hour. No-one had bothered much about the geyser for decades, but a few years ago the decision was made to reconstruct the site altogether. The concrete rings, which had confined the geyser since the 1970s, were removed and it was decided that the forces of nature should be left unrestrained.
