Original - Erosion is a gravity driven process that moves solids (sediment, soil, rock and other particles) in the natural environment or their source and deposits them elsewhere. It usually occurs due to transport by wind, water, or ice; by down-slope creep of soil and other material under the force of gravity; or by living organisms, such as burrowing animals, in the case of bioerosion.
Winters in California bring high tides, which causes sandy cliffs above Pacific ocean to erode. The image shows such an erosion, which in that situation prompted evacuation of the affected building.

Well, the image was taken not to show a beautiful landscape. There are fences all over the place, and they are a big part of that eroding cliff. As a matter of fact I climbed over one of them for a better view, and eventually was lead out by the authorities :( Anyway I added alternative. Maybe you need log out, and log back in to see it.--Mbz1 (talk) 18:42, 20 December 2009 (UTC)[reply]
Added one more taken on a different day from the other side. Please notice bulldozers in the surf.--Mbz1 (talk) 02:36, 25 December 2009 (UTC)[reply]
The fence: If it is considered an integral part of the subject then I consider this a wrong composition. Even if its presence is deliberate the shot doesn't show it. It looks like it is accidentally inside the frame (my very personal point of view). I will certainly not going to oppose since this is probably the best erosion picture in en.wikipedia but I am not so sure that it can not be better. This could be an example: what is the role of the fence? Limit the movement of people. A composition in which the fence plays a role (for instance) is right in front of the viewer, "limiting" his/her movement (not covering the erosion! since this would miss EV)[maybe with a little blur to convey that it is not the main subject] or in one side but limiting the movement of a third person (let's say). The erosion thing then in second plane but completely sharp (and the house with it). No idea of this particular place and therefore not sure if possible but I ask, Isn't it possible something like this moving to the right?  franklin  10:51, 27 December 2009 (UTC)[reply]
I wonder what do you think about alt 2? and about that one File:Cliff erosion in pacfica 4.jpg.Thanks.--Mbz1 (talk) 13:13, 27 December 2009 (UTC)[reply]
More about the place. Almost for all images I climed over the fence myself. For few images , for example original and alt 1 I was transpassing private property, the sign there said that transpassers will get arrested. In many places there sidewalk fell to the ocean already And here the view from the balcony of a nearby home File:Bluff erosion in Pacifica 3.jpg--Mbz1 (talk) 13:29, 27 December 2009 (UTC)[reply]
