Kalliolähde

Kalliolähde is a Finnish term that translates to "rock spring" or "rock well." It refers to a natural spring that emerges from bedrock, often in rocky terrain. These springs are characterized by their source being a fissure or crack in the rock through which groundwater rises to the surface. Unlike springs that emerge from soil or sand, kalliolähteet are typically found in areas with exposed rock formations, such as hillsides or cliffs.

The water from a kalliolähde is often considered pure and clean, as it has filtered through the rock layers. Historically, such springs have been important sources of drinking water for communities located in rocky landscapes. In some regions, kalliolähteet may have also held cultural or spiritual significance. The appearance of a kalliolähde can vary greatly depending on the geology of the area. Some may be small seeps, while others can be more substantial flows of water. The surrounding vegetation might also indicate the presence of a kalliolähde, as water-dependent plants can thrive in the vicinity. The term is primarily used in Finland and other Nordic countries where rocky terrain is common.
