Kill me now, because it'll be another bridge tale.
I happen to enjoy the works of Ambrose Bierce, who wrote several shorties, including a personal favorite An Occurrence At Owl Creek Bridge
(American Civil War era); but, it doesn't really fall into short, short, runs about 3400 words. It can be located here:
(listed strangestly under the letter O) as can other Bierce stories. I like his work, much of it is quite descriptive and gives settings at particular times, years. For additional shorts, there is a menu on the left of the Patagonia.
Additionally, I find the short stories of Raymond Carver to be nicely done; not sure if they'd fit your needs.
There are a few I should recall but am lost, one was a Sherwood Anderson bit, and the one with the escaped mentally ill man, How Beautiful With Shoes
by Wilbur Daniel Steele. The Anderson and Steele stories were in books I read back in college, in Humanities courses, (at least Steele was, not as sure about Anderson, that may have been the English class...it's been a few deciduous decades since then, but they were college level and in that Freshman year).
For a poem of length with several images to be conjured up along with descriptions of all that is occurring, there's The Death Of The Hired Man
by Robert Frost. It can be locationed on Youtube. http://www.youtube.com/watch?v=qNZxHIPueRU
