Abstract
The shallow marine depositional environment of the Miocene aged Astoria Formation directly influences the occurrence of modern – day hazards, such as landslides, and debris falls plaguing HWY 101 near Beverly Beach, Oregon. Elevated sea levels plus continental subsidence resulted in a low energy, marine, depositional environment, resulting in the Astoria Formation. Today these poorly lithified sediments have proven unstable resulting in hazardous conditions for developers and motorists alike along HWY 101 near Beverly Beach, Oregon. Field work will focus on physical properties related to the depositional environment which influence the occurrence of hazards associated with the Astoria Formation today.
