Thor’s Well a deep sinkhole that sits on the edge of Oregon Coast near Cape Perpetua.
This natural salt water fountain is a 20 feet deep hole, also known as the "drainpipe of the Pacific". When the tide is high enough the well is filled with water before being spectacularly emptied again.
When to visit Thor's Well?
Travellers say that it is most impressive during winter storms (can be dangerous though!). During the high tide the waves aggressively splash and quickly fill the hole, and after shoot out with a strong force.
How did the well form?
It took decades for it to form. The well started off as a cave and thanks to continuous waves the top of the cave eventually collapsed leaving a hole through which the water surges upwards.
Is it safe?
It is a beautiful sight, however, approach with caution. During these sudden water flows unsuspecting visitors to the site run the risk of being swept right into this powerful whirlpool.
If you are planning to visit the place to take a nice photo be sure to keep distance.
