From river level to the top of the bluff the bank is protected from erosion by rirap, large blocks stone and concrete.  Access to river level is by clambering down the riprap, wet from recent rains, while loaded with camera, tripod, blind and a comfy seat.  (Note to self: find a better way to tie the tripod to the backpack.)

Remarkably effective.  Unlike the previous day (cold and rainy) I didn't have to use gloves so I was quite pleased with the camera's handling.

It's easy to overlook among the dozens of Common Goldeneyes but notice the male's cheek crescent instead of a round spot, the less rounded head shape, shorter bill and steeper forehead.  The male's head tends to be more iridescent purple-black instead of the Common Goldeneye's green-black:
