Believe it or not, this is a color picture.
It was just that the day was turning gray.
Dennis pointed out this interesting hole with a rock in it.
We are standing at the mouth of the Yachats ("yaw-hots") river at low tide.
At high tide this area is covered with two or three feet of sea water.
I found the ripples in the sand an interesting pattern.
I took this shot with my telephoto lens to compress the pattern.
Here is the same area of sand from a slightly different angle.
I thought this bird looked cool watching the tide come in on the same area we had been walking on.
Another shot of the mouth of the river area at high tide.
Several seagulls are supervising the festivities.
