Researchers conducted the new "photogrammetry" measurements as part of an effort to update maps for pilots. It turns out that Mount Hope is about 1,200 feet higher than thought, the earlier calculation having been made back in the 1930s.
"We've got to bear in mind that this was a pioneering expedition, overland travel with dog teams," a BAS scientist tells the Telegraph of the first measurement.
"They were using relatively lightweight and simple surveying techniques in very, very harsh conditions." Neither mountain comes close to Antarctica's tallest mountain: Mount Vinson is 16,049 feet high, but it is not located in land claimed by Britain.
