Dear Sir, I am getting irritating comments from a creationist who asserts that giant clam shells are lying around on the surface of Mt. Everest and that proves that Mt. Absurd BS I know but I would like a refutation of such drivel from a qualified geologist who has studied the area. Your pictures are great and I appreciate the information in your article.
Thank you for posting it. And if someone can see that you really listened to them, they are more likely to listen to you than if you dismiss them without a hearing. Thanks for the feedback. I think a nice way into this debate is to revisit how Geology developed in the 19th Century. Take the Very Rev. Dr William Buckland see Wikipedia page. He was a theologian within the English Church and also active as a scientist. Initially he thought he could do this — publishing books in both and in support of a Flood hypothesis.
Later in he changed his mind, realising that the evidence was better explained as being caused by glaciation of England. William Buckland sought to reconcile the evidence of his eyes with his Christian faith. In the end, this led him to realise that the Flood was not a historic event.
It is worth mentioning that Buckland would not regard the fossil clams on Everest as evidence for the flood. There are no shells sitting on the surface of the summit of Everest. There are some marine fossils within the rocks that make up the summit area.
These rocks are limestones and Buckland, by analogy with conditions in the Bahamas, would understand that rocks of this sort form slowly in layers. I hope this helps. I have been there. I did see some people, no clams, and the people had climbing gear. So I think the ark theory should be out. Thank you very much for that. Pretty much confirms what I thought must be the case. LOL just kidding about that last part. It was still an extraordinary rush to go on a mobile occasion to the Everest district, especially as by then the topography of the territory was appropriately caught on.
I should utilize my portraits to delineate the geography, as depicted in a paper by Mike Searle and associates, accessible on line by means of his Everest guide website. It measures around 8, meters over the normal ocean level. I would love to see a time line for mount Everest. Also the flow from under the plateau, could we elaborate on that?

Field of view 4 mm. Together he and P Wyn Harris reached m on the NE Ridge, above where Mallory and Irvine were last seen in , and less than m below the summit.
On the approaches and on the ascent he made a collection of over rock samples , now kept in the Oxford University Museum of Natural History. In recent years Oxford geologists have returned to the Everest area as part of a project on the tectonics and petrology of the Himalayan chain led by Professor Mike Searle. An extract from the geological map of the Everest area by M P Searle.
It shows Mt Everest and neighbouring peaks capped by sedimentary limestone and underlain by low grade metasedimentary rocks Yellow Band and Everest Series. These in turn pass down into granite, migmatites alternations of granite and schist and high-grade metamorphic gneisses in the valley floors and to the south. Running the full length of the Himalayan chain is a thick slab of metamorphic rock, the Greater Himalayan Series, which formed in the mid-crust at an earlier stage of the evolving collision between India and Asia.
Its appearance at the surface today is the result of movement on two spectacular shallow-dipping fault systems: at the base of the slab, the Main Central Thrust zone, and at the top, the extensional faults of the South Tibetan Detachment System STDS. Along much of the Himalaya, sediments rest almost directly on high-grade gneiss across the STDS, but in the Everest area there is an intervening unit of lower-grade schists that offers a vital insight into how the top of the slab developed.
Unfortunately, as the photo indicates, these are mostly exposed in near-vertical faces at extreme altitude, and good samples are few.
