Not much information, is there?

Well, aside from the fact it was printed some years ago in a newspaper, who the hell knows if it's true or not. Good chance of it being a made up article to fill space, without a name and such, but then again, maybe it's true.

In this case, we simply cannot confirm nor deny ignorance.

in 2006 or so, i had some contact...right near there....i think anyone could do it...
go to rattlesnake mountain s.e. of I 90 and hwy 18 up there just twenty minutes from frickin seattle
just by going in 4 miles, one can be in the strangest place, remote....on the incidence map, it;s the most noted....a little pocket with no access for thirty miles to the back boundary. in fact it's a mile from a first reported by white man encounter in 1922 or so. i was predator calling and walked away after 40 minutes and leaving grapes in a bag. then i like to returnto the spot after 30 minutes to see the predators snooping. i had two bearguns but hauled azz outta there on my trail honda. I always say i'm willing to go back if with about six or more people. It's a perfectly safe place for a whole group of them... about 7 miles by 6 miles square of rainforest with tangles and steep ravines, humans can do a mile a day

There's not really much of anything to go on from the link you provided. I'm not even sure why you posted this,seeing as it's 43 years old and there's very little proof of anything.The story itself isn't even interesting. It's just repeating the common "bigfoot" sighting.
