Hopefully that article's not paywalled; I'm a subscriber, but this
popped in my general newsfeed.

A few years ago I read or saw something about one crater being suggested
-- in a place hard to access, perhaps on a big private ranch if I recall
right.  Apparently the same researchers are hot on the trail.  I'm
hoping they find the main crater sooner than later.  And I would like to
visit one or more of the secondary craters sometime too.
