According to Rakitin (and on his bio here on the website,) Zolotaryov resigned from Kourokovka before leaving for the trek with the Dyatlov group. That seems odd to resign from the school before actually achieving his certification for category III. Does anyone know where I might find more info on why he left or whether he had plans for after the trip (aside from his comment to his students about how the world would know him after his trek?)
