Fenambosy Chevron
From Wikipedia, the free encyclopedia
The Fenambosy Chevron is one of four chevron-shaped land features on the southwest coast of Madagascar, near the tip of Madagascar, 600 feet (180 m) high and three miles (5 km) from the ocean. It is composed mainly of material found on the ocean floor at . . Chevrons such as Fenambosy have been hypothesized as providing evidence of "megatsunamis" caused by comets or asteroids crashing into Earth. "About 900 miles southeast from the Madagascar chevrons, in deep ocean, is Burckle crater, which Dr. Abbott discovered last year. Although its sediments have not been directly sampled, cores from the area contain high levels of nickel and magnetic components associated with impact ejecta. Burckle crater has not been dated, but Dr. Abbott estimates that it is 4,500 to 5,000 years old." [1]
