CEC. GORDON(ABOVE)ANDJAMESP. Clearing up Big Sky country TEMPERATURE INVERSION holds down odorous particle-laden vapor billowing from a large Montana paper mill on July 20, 1969; prevailing winds fan the haze through the valley toward Missoula, ten miles to the east, where it mingles with smoke from smaller industries and dust from fields. Upset about pollution from all sources, Missoulians supported the state's Clean Air Act of 1967. To see that it was enforced, local women organized GASP-Gals Against Smog and Pollution. Their picket line at the paper plant (right) was only one pressure technique. They wrote to their representa tives, sponsored lectures, and questioned public officials at open forums. Editorial page editor of the Missoulian, Sam Reynolds (left), campaigned "for results." Industries cooperated. Incorporating new technology, the paper company is spending $13,500,000 on modifications to meet state standards by 1972.
