Lyndon: Why would the suit have been disposed of?
I've thought about this myself Lyndon, and actually I can think of a number or reasons why the suit (If one ever existed) would be disposed of. Just for argument sake, let's say it was hoaxed, and the intent from step one was to fool the public with the reason for doing that unimportant.
You get yourself a suit from somewhere and it's delivered to your house. You know at this point the only people who know of the existence of this suit is the creator and his staff, and yourself. Before heading to California you show the suit to a limited number of close friends/family all sworn to secrecy. The number of people who know about the suit is still extremely limited and well controlled. Now you go to California to film your costumed actor, all the way down there you're thinking... What if I get pulled over for speeding? What if I have an accident? What if someone breaks into my car and sees the costume? You know if any of these things happen, the entire plan is out the window. Now if in fact there was a thought of possibly a significant amount of money might be earned by this video, that would make the stress level even higher.
So now you finish filming your bigfoot movie, and it's time to return to Washington. Again you start having those little "What If's" dance around in your head and again you realize if any of those things happen, it's over. You decide it's best to dispose of the suit to lessen the chance of it every being discovered, you don't want to mess up the possibility there may be money made on this film. So how would you dispose of it? You wouldn't want to simply drop it off in a dumpster or in a garbage can along the way back to Washington, it may be discovered. Burn it? I wouldn't, if synthetics were used in it's construction some of those can create very dark or dense smoke. You wouldn't want to attract anyone's attention like a forest ranger or fire spotter. So where would you dispose of it and how, without attracting attention and lessen the chance it will ever be found, you bury it.
If it was me, I would bury it very near the location where the filming was done. I would make sure it was buried far enough from the water and high enough that any subsequent flooding would not uncover it in the future. I would bury it in a place that would be easily camoflagued to hide shovel marks and cover the newly dug up earth. Possibly on the edge of a brush pile, or simply below some pine/fir trees where the needles could be stewn back over to cover the evidence of the digging. Or even under a pile of rocks the could also mask the digging.
So, if there was any metal in the construction of a costume, zippers etc, you have a possibility of finding it, if you look in the right place and IF it exists. Just use a metal detector and follow the same route they rode into and out of the filming area with their horses. I'd limit my search to 150 feet on both sides of the trail I doubt there would have been a need to go further into the woods, and cover the filming location thoroughly. If you find anything remember it was my idea.
