New Re: I tried looking for chevrons with Google Earth
This abstract gives the coordinates of a number of the project's candidate impact sites: [link|http://gsa.confex.com/gsa/2006AM/finalprogram/abstract_114274.htm|http://gsa.confex.co...stract_114274.htm]

If the Long Island crater is at 41.17N, 72.405W then perhaps the dunes at 41\ufffd 0'48.30"N 72\ufffd 2'3.27"W are the chevrons, though there's a bunch of land between the two.

Also, if the Indian Ocean crater is here 30.865S, 61.365E, then maybe it's the dunes at 25\ufffd15'58.97"S 44\ufffd39'50.76"E and elsewhere along the southern coast of Madagascar. They do look awfully large (15 miles in length at one point).

These? :

Here's an interesting looking feature:

Notice the raised bit more or less in the center.

New No, these
The dunes here seem to be right inline with where the crater is supposed to be, and they go way inland: [link|http://maps.google.com/maps?f=q&hl=en&q=madagascar&ie=UTF8&t=k&om=1&z=11&ll=-25.234758,44.520035&spn=0.475155,0.720291|http://maps.google.c...0.475155,0.720291]

Tha 2nd one appears to be volcanic

New A Paper on Australian Chevrons
This paper ( [link|http://library.lanl.gov/tsunami/213/scheff.pdf|http://library.lanl....mi/213/scheff.pdf] ) lists a number of features around Australia that they think may be "tsunamigenic". Unfortunately this particular team hasn't actually checked the features in person to see if they fit the hypothesis. They're only going by satellite images. Still, it's something more specific to look at in Google Earth :)
