Emerald Triangle

Region of Northern California comprising Humboldt, Mendocino, and Trinity counties, totaling roughly 10,000 square miles of coastal range and redwood country. Its cannabis identity dates to the back-to-the-land migration of the late 1960s and 1970s, when urban and suburban newcomers — including returning Vietnam veterans and budget-minded homesteaders — acquired cheap, remote parcels and supplemented subsistence farming with small cannabis plots. Growers there pioneered the American revival of sinsemilla cultivation — removing male plants so females produce unfertilized, resin-heavy flower — and, combined with Afghan Cannabis indica genetics brought via the Hippie Trail in the late 1970s and selective breeding, yielded a domestic product that displaced imported Mexican and Colombian brick weed, especially after the U.S.-backed paraquat spraying controversy. Pound prices rose from roughly $500 in the early 1970s to $2,500–$3,200 by the mid-1980s. Beginning in 1983, the state-federal Campaign Against Marijuana Planting (CAMP) conducted helicopter-based eradication raids each summer, destroying plants and pushing cultivation indoors and into cloned, lighting-dependent production. The region subsequently underwent a contested transition under Proposition 215 (1996) and Proposition 64 (2016). Documented in Ray Raphael's Cash Crop (1985), Martin Lee's Smoke Signals (2012), and Emily Brady's Humboldt (2013).
