    The weeding out of fakes will, perhaps, have a farther reaching effect than simply cleansing the data base. It may also dispel the notion of “dermal ridges” appearing is some tracks. I was present at a talk given some years back by Matt Cowley in which he discussed 1) just how fine and moist dust must be to retain dermal ridges even momentarily, and 2) how effects identical to the “dermal ridges” found on some bigfoot footprint casts are created by the action of pouring plaster into the footprint. He explained how these “dermal ridge” artifacts are created as the plaster poured into the mold quickly dries as each “wave” of the pour partially dries as it comes in contact with the soil. Crowley was able, for instance, to reproduce the “dermal ridge” effect when making plaster casts of impressions in soil made with smooth, hard plastic squares.

    He pointed out that so called dermal ridges have been found in the Blue Creek Mountain (Onion Mountain) casts (which we now know to be Wallace fakes) — even though John Green himself said he could not recall seeing those features in the raw prints. Nor do those features show up in any of the very clear photos taken of the tracks. They only appear in the casts . . . of those fake prints.

    Clearly there is much work to be done to unlearn some of what we think we know.
