Found crater in South America

I was surfing the web and came across this image

I immediately noticed the crater rim and central uplift. Has this
crater been identified before? Is it named? Here is a better image
from the same web site.

I looked around for a better picture that would show the whole area,
but it seems that satellite images of the world are not easy to find.
TopoZone and TerraServer both have nothing and I am at a loss at to
where else to look.

What'll yall reckon?
