When the Pacific Ocean is roiled up, the blowhole at Hearn Gulch erupts with a loud "whoosh!" Debra Mundt recently photographed the blowhole going off.
And here's a nice photo Debra took from the beach, showing the creek emptying into the Pacific Ocean with the blowhole going off in the distance.
Parking for Hearn Gulch is found at mile marker 10.0 in Mendocino County. To learn more about it, and other coastal access points brought to us courtesy of the Redwood Coast Land Conservancy, here is their website: http://www.rc-lc.org/
Thanks to Debra for allowing me to share her photos with you here.
