Near the Panama canal is the famous Valley of square trees. These trees are a unique attraction, as many poplars here, for unknown reasons, have rectangular trunks.
It is believed that this strange natural anomaly not found anywhere else in the world. With its right angles and a clear rectangular shape, the trees baffled scientists for many years.
Experts from the University of Florida and took a few trees to check whether they retain their rectangular shape of the trunk if they grow in other places. It turned out that the unusual square shape of the trees in some way connected with the conditions of the valley. Trees planted in any other place, have the usual form.
