Mysterious places on earth 2

Crookland Forest, Poland (Google)
Over 400 pine trees have been garnering
attention for years.
An entire forest in Poland appears to be
bent over almost 90 degrees at the trunk,
before twisting back straight again and
growing vertically into the sky.
Debate has raged as to what caused the
unusual wood to come to look like it has,
with theories as wide-ranging as torrential
snowstorms and lumberjack growing
techniques.
