I'm not positive about that sinkhole theory, nprev -- looks to me like many (if not most) of the lakes occur within the walls of circular depressions, but it also looks like they fail to fill the entire depression in most cases. Looks more like they might have entirely filled the depressions at some point, but have evaporated down to remnants at this point.
The depressions look more like old impact craters than calderas to me, but that's a hard distinction to make with the resolution that we have. -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain
