In response to the new Saharan Crater story, I was contacted by E-mail by an Editor at Sky & Telescope Magazine. He told me a reader had recently written them about a crater up on on Melville Island, on the northern part of the Sabine Peninsula. Here’s what Gerald Hanner wrote:
I have read with interest your pieces on impact craters — especially
the ones found on Earth. Some 40 years ago, when I was an Air Force
navigator, I used to fly a route from Fairbanks, Alaska, to Thule,
Greenland. At the northern tip of the Sabine Peninsula, on Melville
Island, my ground mapping radar would pick out a circular structure
with a peak in the middle; it sure looked like a crater to me,
although I never actually got a visual on it.
He goes on to say he recently checked for it in Google Earth, and there he found it very easily in this GE satellite photo . He wasn’t sure whether this was an impact crater. Based on what I’ve been learning, I think it is an impact crater. It quite clearly has two rings which is evidence of a strong impact. The main crater is about 7.5 km wide, the secondary crater is almost 14 km wide! One expert confirmed it wasn’t in a database of impact craters (I checked out this GE database of known craters as well), but didn’t have enough data to confirm. Can any other experts comment?
Thanks to Stuart Goldman, Associate Editor for Sky Publishing, for bringing this to my attention.
[EDIT 12:20 EST: Looking nearby, there appears to be an oval-shaped crater just to the northeast of this new crater. Also, there are other possible craters to the south and southeast. Very interesting!]
