Is it this Richard Hoagland?
Richard Charles Hoagland,[1] most commonly known as Richard C. Hoagland, (born April 25, 1945) is an American author and a proponent of various conspiracy theories about NASA, lost alien civilizations on the Moon and on Mars and other related topics. Claims from his personal biography[2] and publication[3] include having been curator for a science museum in Springfield Massachusetts at age 19 in the mid-60s.[4] Hoagland does not have any scientific training.

He has some background with NASA but I don’t know much at all about him. Never heard of him before yesterday. Doesn’t matter about him, though. If that geologist comes forward and verifies the story, OK ‘cause he is credible. At that point, Hoagland’s opinion matters not.
