Yes, but it's hard to judge things that you have no reference frame for. There's another story about the Grand Canyon. Apparently the first Spaniards to reach it estimated it to be a couple hundred feet deep, and thought the part of the Colorado that they could see was about six feet across. It was a mile down and 200 feet across, but they had no concept of a canyon that big.
