A typical day of creekwalking could take anywhere from five to ten hours and empty a tank of gas

That is a LOT of walking!

Maybe he means he tanks up on this, before leaving:

That'll fill your tank with gas!

I am really curious how this type of thing is authenticated- since I have an uncle that makes arrowheads and things of that type and does them the same way they were made at the time. The obsidion or flint used might be dated and I could understand if modern tools were used it would prove an item a fake but if it was done as it was in the past how would anyone really know for sure? My uncle tells people he made the stuff he has but what if a person was less than honest? I do realize artifacts do turn up that are truly amazing- a cowboy friend of ours got off his horse one day to answer a call to mother nature and found an awesome stone (peace?) pipe.
