Yep, that’s right - a 1,000 ft. mushroom cloud, and no, that doesn’t mean above-ground nuclear testing has resumed in the Nevada desert. It just means that the artist who built Crude Awakenings - a 100 ft. tall oil derrick - wanted to blow it up at the end of the festival (to "dramatize the worshipful relationship and dependence modern man has toward oil"), and to do so he used 900 gallons of jet fuel (apparently off-spec fuel given to him by NASA) and 2,000 gallons of liquid propane, not to mention the timber and steel used in the structure. You can see it on YouTube here....
