Ah yes ..the story you read was about Admerial Byrd in the 40s... He said during a debriefing that as he flew over the poles ,he seen things that should not be there like green grass ,trees and flying creatures... Gets really good if you read the whole thing but he was told he was to never talk about what he had seen.. This goes into the hollow earth theory.. It was said Hitler had found it using tunnels under Artic ice.. As far as why no north to south expos... The poles interfer with gps and compasses
