Natural Changes:
3 surf fishermen came at 6:45 to dig sand crab, now fishing successfully. Each had about 6 fish. One had his small poodle dog (in sweater) with him. Very happy to talk to me about techniques, condition etc., for surf perch fishing. It was a pleasure to see this recreational use of the beach, obviously important to mental/emotional and physical health of those gentlemen.
Driftline with much kelp and wood. Kelp is starting to break down and disperse. Large masses of kelp deposited on beach during November’s big storms. Siltcoos River is still far to the south of the foredune of mile 161, with a vast, quiet flat beach between the river and the foredune. Five seals were in the river. Two dead, decomposing seals on the sand.
