Green and white lichen

The Canada/US border marker on the Boundary Bay beach has a tall cement base, lapped at the bottom by the highest tides. Looking for seaweeds the other day, I made the marker my turn-around point, and stopped to look at the marker itself.

On half of the Canadian side, above the reach of the tides, a colony of interesting lichens has settled in.

Green spots, up to about 3 inches across, with white borders.

There's even a little broken heart.

I was just carrying the little pocket Sony, since I'd come directly from the hospital, so the detail gets lost in noise. Next time, I'll make sure to carry the good camera, and get a better look.
