One of the rare, stunningly clear days at #pointreyeslighthouse . Such a gorgeous scene and memory of the ages past where sailing ships sailed north from #sf and prayed not to ground. #PointReyes is the most #windy place on the #pacificcoast and the second foggiest place on the North American continent. Weeks of fog, especially during the summer months, frequently reduce visibility to hundreds of feet. The #pointreyesheadlands , which jut 10 miles into the #pacificocean , pose a threat to each ship entering or leaving #SanFrancisco Bay. Operating as of #1870 , the historic Point Reyes #lighthouse warned mariners of danger for more than a hundred years.
