Poland's Mysterious Crooked Forest
In a tiny corner of western Poland a forest of about 400 pine trees grow with a 90 degree bend at the base of their trunks  all bent northward.
Surrounded by a larger forest of straight growing pine trees this collection of curved trees, or "Crooked Forest," is a mystery.
Planted around 1930, the trees managed to grow for seven to 10 years before getting held down, in what is understood to have been human mechanical intervention.
Though why exactly the original tree farmers wanted so many crooked trees is unknown.
