When one landscape consumes another, it may leave a “graveyard” of sorts behind.

That’s what happened with Neskowin Ghost Forest, an ancient forest off the coast of Oregon. When the tide is low, the petrified stumps of roughly 100 trees, the remnants of an ancient Sitka spruce forest that once stood hundreds of feet tall, rise from soft sand and seawater, alongside marine life and tidal pools.

In their prime, the trees that make up today’s “Ghost Forest” were similar to present-day coastal rain forests. It is estimated that they stood 150-200 feet (46-61 m) tall and were at least 200 years old at the time they were buried. The stumps were unearthed when turbulent storms swept away sand during the winter of 1997-98. It was originally believed that the trees had died slowly, as the roots were submerged in saltwater. However, geologists now theorize that the ancient trees, carbon dated to around 2,000 years old, were broken and toppled during a major earthquake that hit the area in the early 1700s. The shift in the earth’s surface dropped the forested land into the tidal zone. When the ocean water rushed in, it buried the decapitated trunks in the mud. This staved off decay and preserved the forest remains for centuries.

The stumps are not always visible; low tide during the winter months is the best time for viewing. Neskowin is one of over thirty “ghost forests” along the Oregon and Washington Coast, though most of the others are not as dramatic, looking more like roots.
