Maidonlähden

Maidonlähde is a Finnish term that translates to "milk spring" or "milk well". It refers to a phenomenon observed in certain natural springs where the water has a milky or cloudy appearance. This unusual coloration is typically caused by the presence of fine suspended particles, such as clay, silt, or microorganisms.

These particles can be stirred up from the spring's bed by water flow or geological activity. In some cases, the milky appearance may be temporary and disappear as the sediment settles. Other times, it can be a persistent characteristic of the spring. The composition of the suspended material can vary, influencing the exact shade and opacity of the "milk".

Maidonlähde springs are often found in areas with specific geological conditions, such as glacial deposits or sedimentary rock formations that are prone to erosion. While the appearance can be striking, the water from these springs is generally safe for consumption after appropriate treatment, though its aesthetic quality might be affected. The term is more descriptive than scientific, highlighting the visual aspect of these natural water sources.
