No idea.
Some called it the Purple Paralyzer, but that is old school (the 70s) and may have been different.
I think any bud from up there may have gotten a bit purple as it got really cold at night, even in August.
I bet it was a cross or even just a regular variety available back then.
Skunk #1, Blueberry, Northern Lights were around back then...
It could have been one or more.
One thing for me was the smell and the absolute power. No one called good pot "kind bud" back then, the generic name was skunk.
I bet one of the main reasons it sticks out in people's minds is that even back then, the guy(s) really knew how to grow and cure.
It was great pot, well grown outside and cured perfectly.
