Long Description:

NOTE 9/25/17 This sign has been replaced by a new sign with a different topic.

This sign was located at the Yaquina Head Lighthouse parking lot

Marker Name: An ancient lava flow
Marker Text: Fourteen million years ago, lava gushed from huge fissures in eastern Oregon and Washington and flowed 300 miles (500 km) to the sea.
Rugged and eroded
Yaquina Head is a westernmost toe of the Ginkgo Basalt flow of the Columbia River Basalts. Erosion and faulting have shaped this “lava delta” into its present rugged form.
Fossils remain
Clams, snails, marine mammals and other animals are fossilized in the buff-colored sandstone cliffs known as the Astoria Formation (located behind the sandy beaches).
The forests beyond
From here on a clear day, you can see perhaps 15,000 acres (6,000 ha) of coastal forests. The Bureau of Land Management manages forest watersheds, wildlife, cultural sites, and recreational opportunities on 2.2 million acres (880,000 ha) in western Oregon.
