The site Oppenheimer located features a ring of stones where a tent once stood and appears to match historic photos taken during the 1912 expedition. "Conservators from the New Zealand-based Antarctic Heritage Trust have been asked to verify the historic find," the NSF wrote.
The area will be recorded and searched to look for artifacts from the original expedition. Tents and other sites from early 20th century expeditions have also been found and preserved, some with a wealth of artifacts.
The team that climbed Mount Erebus in 1912 included geologist Raymond Priestley; they took geological specimens and mapped the area. Scott's expedition was more focused on gleaning scientific research from their mission than Amundsen's was.
The 1912 expedition was preceded at Erebus by the 1907-1909 Nimrod Expedition, mounted by explorer Ernest Shackleton, which failed to reach the South Pole.
The NSF team is studying the 14,500-foot Erebus, which is interesting geologically beyond being the southernmost volcano. It is also home to Earth's only long-lived lava lakes.
