The Oregon Coast is dotted with strange structures sticking out from the sand. After further inspection, it was discovered that they were actually tree stumps and root networks.

There are a number of theories about how the grotesque formations came about. General consensus is that about 300 years ago, a massive tsunami hit the coast, leveled an entire forest, changed the whole landscape - maybe squashing a local tribe or two - and leaving the eerie monuments.

Guy DiTorrice, dubbed Oregon Fossil Guy for his expertise in beach fossils, says that the sand levels are particularly low, allowing for the structures to surface. Sand levels are dictated by certain conditions like tides, weather, and currents. He thinks that there might be more things rising out from the sand if the levels drop even more. He says that those levels would be great for fossil hunting.

There are also other theories regarding the ghost trees. It might have been a massive earthquake that sank the land and submerged the poor trees. Another theory is the human factor. It might have been just loggers from the 1700s who razed the coastline for a number of different reasons.

Another such site nicknamed "ghost forest" was found, and scientists theorized that it was a result of an earthquake so strong that it split the land and dropped everything - trees and all - straight into the sea.
