In the winter of 1977, Yosemite National Park became the unlikely setting for a tale that blurred the lines between adventure and illegality. Two waiters from the Ahwahnee Hotel, emboldened by a severe drought that had reduced snow levels, ventured deep into the park on a snowshoeing trip. They stumbled upon a Howard 500 aircraft, crashed and abandoned, with a cargo that was far from ordinary—6,000 pounds of Mexican marijuana.
The initial discovery by the servers triggered a complex operation involving multiple federal agencies, as the site turned into a crime scene. Despite efforts to salvage the soggy, frozen marijuana and secure the area, the lake's remote location and icy conditions thwarted immediate recovery of the plane's further contents or its deceased occupants.
As word of the abandoned stash spread, climbers and park locals, known affectionately as "Dirtbags," seized the opportunity. They turned the site into what was dubbed "Dope Lake." Using ice axes and later chainsaws, they mined the frozen lake for marijuana. This led to an improvised gold rush, where climbers could make significant sums from selling the salvaged marijuana despite its compromised quality due to water and jet fuel contamination.
This bizarre episode peaked when park rangers, dubbed "Danger Rangers," conducted a raid in April 1977 to shut down the operation. Remarkably, despite the scale of the activity, only two individuals were arrested, and those charges were subsequently dropped due to a legal technicality.
The event has since been immortalized in climbing culture and is a vivid example of the unexpected stories that national parks can tell. For those intrigued by this wild chapter of Yosemite's history, the documentary "Valley Uprising" explores it in more depth, alongside other legendary tales of Yosemite's climbing scene.
