• Per Ciao magazine [Ciao! was a pioneering gay male travel magazine in business for most of the 1970s] December 1976 issue cites nude beaches in Oregon – there were two, one being Mount Pisgah. “This is a beautiful bird sanctuary southeast of Eugene. Used to be a favorite place for glider enthusiasts. Now the skinning dippers are here in force. The beach lies along the Willamette River. Once this was polluted…not it has been cleaned and at this writing was quite safe. No hassling at present, but some legislation is due up for a vote soon.”
