At least one of these (first) is from the cancelled Powder Ridge festival. Here are a couple links with lots of photos and info, including that photo:

I did not know about this - this is pretty cool. Read on:

The Powder Ridge Rock Festival was scheduled to be held July 31, August 1 and August 2, 1970 at Powder Ridge Ski Area in Middlefield, Connecticut. A legal injunction forced the event to be canceled, keeping the musicians away; but a crowd of 30,000 attendees[1] arrived anyway, to find no food, no entertainment, no adequate plumbing, and at least seventy drug dealers. William Manchester wrote: "Powder Ridge was an accident waiting to happen, and it happened."[2] Volunteer doctor William Abruzzi declared a drug "crisis" on 1 August and said "Woodstock was a pale pot scene. This is a heavy hallucinogens scene."[3]

pretty sad, or funny, depending on your point of view. So I guess those that went found that there was not much to do except maybe get naked. Oh well, lets just have some sex then and go home....:)

The second link posted above has quite a few naked pics. They are not copyrighted but a notice appears on the website not to distribute them. They have historical significance and so they should not be reposted.

here are a few from Powder Ridge that I think I can post. I'm also reposting the pic that I posted earlier as it has now been identified as being from Powder Ridge.

Looks like nudity was rampant here, with a lot of skinny dipping..

Takes me back...

here is a partial list of bands that were suppose to play at Powder Ridge until the event was canceled. Police patrolled the roads leading to the area, telling people the festival would not go on. It didn't work. 30,000 showed up anyway and many got naked. Just see if you can spoil our fun!

LEd Zeppelin
Sly and the Family stone
The Allman Brothers
Van Morrison
Janis Joplin

Chuck Berry

James taylor
Jethro Tull
Little Richard

my god, what a line up! :)

30 of the 48 music festivals scheduled for 1970 were cancelled, mostly due to local opposition. CIA snoops frequented these festivals, and considered them to be not much different than anti-war protests. To them it was all civil unrest. But nakedness and sunshine and non stop music from some of the biggest names in rock - man, how can anyone top that?

a couple of sexy pics from misc festivals..or maybe not but they're nice..
