Circle Features Found Using Google Earth

Circle Features Found Using Google Earth

The coordinates for a number of new circular features
found by various people using Google Earth are given in:

In Re: Consolidated Impact Crater Database post #1415796 by "ekafeman " at:
http://bbs.keyhole.com/ubb/ubbthreads.php?ubb=showflat&Number= 1415658

The two of the most interesting are:

1, Zhongcangxiang 2, China at 31°59'39.17"N 85° 9'13.94"E
This is about 18km WSW of Zhongcangxiang feature at
32° 2'40.34"N 85°20'1.97"E) It is about 0.03 km in diameter.
http://bbs.keyhole.com/ubb/ubbthreads.php?ubb=showflat&Number= 572974

Zhongcangxiang 2, like Zhongcangxiang, is a "conspicuous 
simple round depression." It is in a very distinct circular
in what appears to an otherwise featureless alluvial surface
of some sort.

2. Rodillo Beach (?), Chile at 26°58'32.26"S 70°47'27.83"W
Although it is only about 0.02 in diameter. This feature is
much more ambiguous. However, it still interesting. Anyone

Unfortunately, it is impossible to tell what both of these 
features might be from aerial photography alone. It is in
a location where anyone taking in the sun at Rodillo Beach
might be able to visit it.

The other circular features seem much less promising. Still,
it is interesting to see what sort of features people are finding
using Google Earth.

Best wishes,

Identified Flying Objects - Wethersfield, Connecticut, Meteorite Fall

Identified Flying Objects - Wethersfield, Connecticut, Meteorite Fall


Identified flying objects byRon Robillard

The article starts:

"It was 40 years ago this month that an alien visitor 
dropped in on Wethersfield." 

This article is about the meteorite that crashed into the 
house of Paul J. and Minnie Cassarino on Middletown 
Avenue, Wethersfield, Connecticut, early on the morning 
of April 8, 1971. It also mentions the November 1982 
fall, which hit a house on Church Street.

Wetumpka (impact) Crater Run

Wetumpka (impact) Crater Run


Crater Run scheduled for Riverfest, The Weptumka
Herald, April 9, 2011.
http://www.thewetumpkaherald.com/sports/outdoors/article_3b804da6-6225-11e0-8545-001cc4c03286.html
 


I wonder if the Wetumpka impact crater in Alabama is
only impact crater that has its only regularly scheduled
foot race associated with it? Also, would the Wetumpka 
Crater Run T-shirts be considered a meteorite-related 
collectible (memorabilia)?

Yours,

Corossol Structure, Sept Iles Harbour, Gulf of St Lawrence, Canada

Corossol Structure, Sept Iles Harbour, Gulf of St Lawrence, Canada


Higgins et al. (2011) reported a new suspected impact crater near
Sept Iles Harbour, Gulf of St Lawrence, Canada at 50°3’N, 66°23’W.
It is about 4 km in diameter and has “a central uplift that rises to 
about -70 m and an annular valley ~160 m deep.”  They report 
finding “planar deformation features,” “phosphatic/sulphide melts,” 
“suevite,” and other possible impact related materials. This is
certainly a promising structure.

Although the title of the abstracts indicates that it is Pleistocene 
in age, the age of this feature remains uncertain and could possibly 
be anytime between 13,000 BP and Ordovician in age. It is still 
possible that this is a pre-Pleistocene exhumed landform. The 
paucity of sediments within the structure is not necessarily an 
indication of its age. This could simply mean that the center of 
the structure has been scoured out as the result of differential 
erosion of the different strata composing it.

This fascinating structure definitely deserves further additional 
research and publication of additional full-fledged papers 
containing detailed information about its structure, age, origin, 
characteristics, and evidence for hypervelocity impact.

“The Corossol Crater is a complex crater ~4 km in diameter 
with a central uplift, a prominent moat, and multiple, 
low-relief ridges. The minimum age is ~13 ka. The impact 
origin is confirmed by a sample of suevite”
