Cape Creek Landslide
The Oregon coast changes daily, sometimes in ways that are very visible to residents and visitors. Constant wave action and persistent ocean currents shape the coastline; winter storms being the most dramatic agents. Summer patterns also shift the beach sand allowing the observant to see subtle changes of the season reflected in the shoreline. The sea cliffs and dunes provide ample evidence of the force of nature and the influence of people over time. The geology of the coast is variable, but often unstable, making it a challenging environment for permanent structures. To visualize this, consider the 1999 Cape Foulweather landslide on Highway 101 or the destruction of the Bayocean Spit in the 1930s and 1940s.
Understanding the dynamics of the Oregon coast helps us interact with this environment more effectively. The Department of Oregon Geology and Mineral Industries provides useful background information on the landslides on the coast.
