An interesting phenomenon has been observed where icicle stalagmites have formed, in addition to examples of the more familiar stalactite configuration.
The upward-growing icicles have appeared at the Estonian mining museum (Eesti kaevandusmuuseum) in Kohtla-Nõmme, Ida-Viru County.
Museum director Etti Kagarov told ETV news show "Aktuaalne kaamera" (AK) Sunday that the unusual formations were the result of a combination of humid conditions and freezing temperatures.
Kagarov said: "It is very humid here, where moisture falls from the ceiling, while the cold rises upwards from the ground, so falling drips form inverted icicles."
