Over at Cryptomundo, Loren Coleman takes an interesting look at "blobsquatches," blurry indistinct objects in photos that could either be a real, live Bigfoot or, well, a branch, a shadow, a rock, a tree stump, a smudge on the lens, etc.

Higgins expanded what he presented at Willow Creek, and published his March 21, 2004 revised paper, which can be found online here: "Evaluating Purported Sasquatch Photographic Evidence".
Higgins wrote within that paper: "Any photo requiring equal parts interpretation and imagination (photos sometimes characterized as ‘blobsquatches’) should be discounted."
