True.
Mountain Goats show little resemblance to their Asian and European relatives.
"The lineage of the Mountain Goat is obscure because glaciation and erosion in steep mountains have destroyed any previously existing goat fossils".

I don't think seasonal browsing at timberline or treks through forests to licks make them forest dwellers any more than occasional walks across farms make Bigfeet farmers, do you?
So, how many fossils of other late Pleistocene arrivals might have been pulverized?
You are missing a point here.
Its an example of an animal whose geographical distribution is much more restricted than bigfoot's supposed habitat. Even within PNW, mountain goats distribution is smaller than bigfoot's (as inferred from sighting reports). Despite their relatively small geographicdistribution, prone to erosion and glaciers, they are present at the fossil register.
Here's a quote from the very article you linked (
http://www.asa3.org/asa/resources/Miller.html):
Because of the biases of the fossil record, the most abundant and geographically widespread species of hard part-bearing organisms would tend to be best represented.
See? Geographically widespread species have beter odds of preservation. You are talking about a species that -if real and if sighting reports are as reliable as investigators claim to be- lives at a huge chunk of North America, thus increasing remains preservation chances.
As for the odds on fossil preservation, you must note that the estimates include animals without hard parts, whose species and specimens number far outnumber vertebrates, but are much harder to preserve due to the very absence of resistent parts. Also, it takes in to account a time span that is by no means relevant to the case (thus increasing the number of species - we're talking about a time span roughly coincident with
H. Sapiens' existence) in point and also factors such as metamorphism that has little impact on the preservation or not of remains dating from the Pliocene to the Holocene. Note that the very article shows examples of forest-dwelling vertebrates.
Note also that a bigfoot's femur has more odds of resisting transport than the femurs of mountain goats or small horse ancestors...
One more time, you may keep on presenting reasons on why there should not be preserved remains, and I can keep presenting examples of preserving remains. This will not change the fact that the fossil register provides no backing to the claim "bigfeet are real".
On a sidenote, I always found ironic to see a variant of an argument used by creationists (incomplete fossil record) being used to back the lack of support for bigfeet...
It's not surprising there are no known Sasquatch fossils. It would be surprising if there were!
Again, you are missing a point.
And the point is: The fossil register does not provides backing for bigfeet/sasquatch as real creatures.
To say "they were not found yet" or some other variant, is a logicall fallacy, an argument from ignorance:
