Are there any well known occurrences of soil creep, downhill creep, or surface creep? I'm doing a project and I can't seem to find anything.

Soil creep is a very common occurence. I see it all of the time, driving on the interstate, along small streams and in the news in different forms. Soil creep is the slow, down slope movement of soil under the influence of gravity. Frost heave, thermal expansion and contraction of the surface, alternate wetting and drying of the soil can cause soil creep.
Any process which occurs at a rate proportional to surface area and moves soil normal to the slope surface will create a soil creep that is proportional to the soil gradient. A basic example of this would include soil freeze/thaw or wetting/drying which occur at the soil surface and thus proportionally to surface (as opposed to horizontal) surface area and when expanding move soil normal to the surface, but tend to settle vertically. These processes lead to a net displacement with a horizontal component proportional to the sign of the local slope, acting at a rate proportional to surface area, which increases at a horizontal rate of one over the cosign of the local slope, leading to net horizontal transport proportional to the local slope gradient.

I googled for images of "soil creep" and got 88 hits--so I think you'll get some good examples there. Also, if you google on +landslide and +creep (which you may have done) you'll also get lots of illustrations at least.

You may be able to find information on creeps in alaska. Because creeps happen on permafrost usually Alaska has the ideal conditions for it.
