The Emerald Triangle is a region in Northern California, named as such due to it being the largest cannabis-producing region in the United States. The region includes three counties in an upside-down triangular configuration:
Growers have been cultivating Cannabis plants in this region since the 1960s, during San Francisco's Summer of Love. Growing cannabis in the Emerald Triangle is considered a way of life, and the locals believe that everyone living in this region is either directly or indirectly reliant on the cannabis industry. The industry exploded in the region with the passage of California Proposition 215, which legalized the use of cannabis for medicinal purposes in California. The passage of Proposition 64 in 2016 legalized the general sale and distribution of cannabis.
When growing cannabis was illegal, this area was remote with limited law enforcement. The area has developed a reputation for cannabis with exceptionally good flavor and cannabinoid profiles.
The total population in the Emerald Triangle is 236,250 according to the 2010 census. The majority of the population is widely spread throughout the woody hills and mountains that make up the area. With an area of 11,138 square miles, the Emerald Triangle population density is 21/mi2.
In this sparsely populated region, the largest urban area is the city of Eureka in Humboldt County with a population approaching 50,000 people. The second and third largest cities, by far larger than any other cities in the region, are Arcata (also in Humboldt), with 17,231 people, and Ukiah (in Mendocino), with 16,075 people.
There is an environmental impact from outdoor cannabis production in the Emerald Triangle, which is largely unregulated. These effects include illegal damming, diversion and taking of water from streams (especially during summer), and also pesticide-laden runoff into streams, all of which may degrade critical salmon fisheries. Clearcutting and roadbuilding for the cannabis plantations can also degrade the environment and endanger salmon. The grows often occur illegally on public land.
In 1984, Humboldt residents filed a federal lawsuit claiming they had been subject to illegal surveillance by U-2 high-altitude reconnaissance aircraft deployed by the California-based multiagency task force started the year prior, the Campaign Against Marijuana Planting.
The Lookouts, founded in 1985 by Larry Livermore, who also founded Lookout! Records, was Tré Cool's first band. The punk rock band named for the fire lookout at Iron Peak in Mendocino County, which led local marijuana growers to threaten to burn down Livermore's house for bringing too much publicity to their hilly isolated region of the Emerald Triangle near Spyrock. The band wrote many songs about the surrounding area on Mendocino Homeland and Spy Rock Road, an album named for the road lined with marijuana grows that leads to Iron Peak.
On the TV show Lost, during flashback scenes in the episode "Further Instructions", John Locke picks up a hitchhiker who happens to be an undercover police officer on State Route 36 and brings him back to a farm near Bridgeville, where they grow marijuana in a greenhouse.
Netflix's 2018 television series Murder Mountain examines the high rate of missing people and murders in Humboldt County. The show covers the history of illegal marijuana farming including the relationship of local farmers and local authorities as the area attempts to transition into a legal cannabis industry.
Environmental damage from pot farming has been a major problem for decades. Drug traffickers growing illegally, often on public land, use pesticides and fertilizers that have poisoned wildlife, including endangered spotted owls and Pacific fishers. Growers have clear-cut trees, removed native vegetation, diverted streams, [and] caused erosion
