The Southern Oregon coast is known for turbulent seas, especially in winter. Any time of the year can be subject to "sneaker waves" that can be very dangerous, and catching you off-guard can toss you off a bluff into the ocean!
Sneaker waves can also create beautiful artwork crashing against the rocky shore. Taken with my Canon EOS 6D and a EF 24-105 lens at 105mm, f/20, 1/125 second, IOS 400.
