The hope was to lower a drill through 14,000 feet of Pacific Ocean water off the coast of Mexico and drill some 17,000 feet through relatively thin crustal rock.
Due to geological processes such as crustal movement, weathering, and rain erosion, a wonder of stone forest landforms mainly composed of yellow sandy conglomerate with various shapes was formed.
The idea was...if there was some other body there and it finally crashes into the Earth, it blows off all this crustal material from the Earth...As well as from the impacter itself.
