I hear you there, as I looked at that also. Its tricky to say, cause one photo is from a higher vantage point and one is from in the "pit" (the video).
Although, from what I gather the pics are from 2007, so, it has had over 5 years to over grow and washout?
The guy in the video should have showed a newspaper date for sure, as it leave room for speculation. Maybe he should go back and get a shot with a news paper to verify.
You can click the link and it says on the bottom right that the photos were uploaded Dec. 2008?
