View looking south along Salmon Creek Beach on 22 April 2016:
And here's a view looking north (below). The entire beach looked like this. Do you have any guesses about what's creating those white strand lines?
The next picture will give away the answer:
There were uncountable numbers of By-the-wind Sailors (Velella velella) washed ashore today...most were no longer alive, hence the white color.
This followed at least a day and half of southerly winds. Seawater temperatures rose to ~14.5°C (58°F).
Hope you had a nice Earth Day!
