Loading...Some loyal Tuskamers are chatting in a comment thread regarding “paleo-lagoons” of South America and the American Southwest. I am not entirely convinced of an ET origin for such features (or even Carolina bays for that matter). Still, the chat had not specifically mentioned the odd bays of Bolivia, so I thought I would drop in a Google map box and show them off — whatever they are.
Hi George,
Do you have the GPSs for that place? Whatever caused them, they look to be a very good match for the ones in the American Southwest. And there is nothing in the standard uniformitarian toolkit to explain them. I’ve already cataloged hundreds of them. Clearly the ones in Bolivia belong in that catalog.
I am focusing my efforts closer to home on studying the blast burned rocks here in California for the time being. But the ‘square craters’, or ‘square bays, or ‘palaeolagoons’, whatever we agree to call them, are an inigma recently revealed by satelite images, that begs to be explored, and hopefully explained. They are high on my list of ‘must go see, and get samples from’ places.
Hi Georg
In my opinion the scars formed by low-density meteoroids are very shallow, compared to the craters formed by denser bodies, they are very sensitive to the relief and erosion. I put an image that can help to understand this hypothesis.
