I had some slope work out at Dabob Bay on the north end of Hood Canal. Dabob is well known to oyster fans. The broad tide flats on the upper bay, warm summer temperatures (see below) and clean water provide ideal oyster growing conditions.

I was there during an exception low tide and had some company on the beach.
The folks above were a group of biologists doing a survey of the tidal flat life.
The tide was out far enough to expose the eel grass.
Any plenty of oysters growing on various substrates. These were on glacier erratic boulders.
