Is there anyplace a human being has not touched on earth not including bottom of the ocean?

There are several areas we havent touched. There are many square miles in Alaska that man hasnt walked on because it is so remote and the ground is either too wet or tundra. There is a cave in New Mexico that has just been discovered that is 200 miles long and parts of it havent had a man's footprint in it. New caves are being discovered all the time.
