- EgPm-116, Edworthy Park: Edworthy Fan is listed as an archaeological site on the basis of the bone occurrences, but its chief importance to archaeologists is as an example of certain geological processes. This fan was built out over two terraces of the Bow River. Each of the terrace surfaces was available for human occupation for as many as several thousand years before fan encroachment. In contrast, the fan surfaces were stable for only a few hundred years. Thus the fan surfaces may preserve well separated archaeological components while the terrace surfaces may yield mixed components representing accumulation over several millennia.
