Columbian mammoth [SEP] Natural traps
Many specimens also accumulated in natural traps, such as sinkholes and tar pits. The Hot Springs Mammoth Site in South Dakota is a 26,000-year-old, roughly -long sinkhole that functioned for 300 to 700 years before filling with sediment. The site is the opposite scenario of that in Waco; all but one of the at least 55 skeletons—additional skeletons are excavated each year—are male, and accumulated over time rather than in a single event. Like modern male elephants, male mammoths primarily are assumed to have lived alone, to be more adventurous (especially young males), and to be more likely to encounter dangerous situations than the females.
