Haystack Rock 草垛巖

On a remarkable stretch of Oregon's coast called Cannon Beach sits a mammoth monolith that formed as a result of lava flow 10 to 17 million years ago. At 235 feet tall, the rock formation is the third tallest intertidal structure in the world. Surrounded by shallow tide pools, it allows up-close-and-personal access, which draws in 200,000 visitors annually. Photo by Shutterstock.

隨著1億到1.7億年前熔巖流過，在俄勒岡州（Oregon）海岸一塊引人注目的叫做坎農海灘（Cannon Beach ）的外延海灘處形成了一座龐然大物。憑借著235英尺的高度，這座巖層成了世界第三高的潮間帶結構。巖層由淺潮帶環繞，允許近人們距離接觸，由此每年吸引了200,000游客。由 Shutterstock拍攝。
