Highway of tears area tie to Z ?

I found that Paradice valley British Columbia Ca . park ,which is not far from the infamous highway where many young girl hithickers bodys were found google/ Wiki highway of tears

my uncle was a welder on the alaska pipeline in 69-72-3 ? as I remember ,he told kind of in a hush tone to my Dad of all these young indiguous girls (eskimo/ Indian ) that were running away from the reservations or places only they lived . said you just wouldn't beleive it unless you saw it .
I read 5000 went missing between mid 60's to 89 ? and it said as many as 50000 may have gone missing from the start of auto travel .
Z would have heard of it and that would be hard to ignore , what do you think ?

Damn, that is a shitload of missing people! So this was in Canada?

Yeah Canada BC. Highway 16 , 450 miles also known as park to park highway says 16 -40+ victims
thats not to say that 5000 were abducted ,met foul play, just they hitch hiked out of there and disappeared, some wanted to never have anything to do with the reservation again
