Vocalization in Arizona (2014)
Account
At dusk on the first night at the research camp, the witness heard a distant roar or yell with the unaided ear. A short time later a second vocalization was captured on the recording equipment. When cleaned up later it sounded non-human with a very deep ending and did not match known animals.
