Title: Have I found a meteor crater?
Post by: craterFinder on 29/01/2012 05:00:43

What do you guys think of this? The lat/long are not registered as craters in any database, I was wondering if i should explore this further based on the what i can see in Google Earth, what do you guys think?

The size is about 700 meters in diameter the other is 2.7km in diameter

Found in Northern Territory, Australia on google earth

22°49'22.65"S, 133°45'25.11"E

and

22°46'41.63"S, 133°59'12.44"E

Cheers!

Your alleged crater has concentric features ...

Such features can occur by erosion of domed structures  ...

Your first coordinates are hills and ridges, not craters.

Agreed - look to the northwest just a short distance away from the first there is a similar feature that is not round. These are due to differential weathering leaving a circular feature.

The second looks to me as the beginning phase of formation of the same erosional feature that caused the first. Then again, it could just be a difference in vegetation. But a difference in plant growth usually means a change in the underlying geology.
