Chinook was a counterculture underground newspaper published weekly in Denver, Colorado from Aug. 21, 1969 to Jan. 21, 1972. It was a member of the Underground Press Syndicate. A total of 117 issues were printed. In 1972 it merged with Boulder magazine to become The Straight Creek Journal, which considered itself an alternative press rather than an underground press publication, publishing weekly from Feb. 10, 1972 to Aug. 7, 1980. According to Abe Peck in his memoir Uncovering the Sixties, the original underground Chinook started to fall apart after a number of staffers left to become followers of Guru Maharaj Ji, who visited Denver and established a mission there in late 1971.
