Nope. The bone beds at the base of "Head-Smashed-In-Buffalo-Jump" are meters thick. 13 I want to say? The plains tribes of the area were running huge herds off there for a very very long time. >The buffalo jump was used for 5,500 years by the indigenous peoples of the plains to kill buffalo by driving them off the 11 metre (36 foot) high cliff. Further... >The cliff itself is about 300 metres (1000 feet) long, and at its highest point drops 10 metres (33 ft) into the valley below. The site was in use at least 6,000 years ago, and the bone deposits are 12 metres (39 feet) deep. Big damn herds, for a damn long time.
