The article says the snowshoes were discovered on Gurgler Eisjoch glacier. There's no entry in Wikipedia (en.wikipedia, anyway) for the glacier, but there is a mention of a "Gurgler Eisjoch" mountain pass (https://en.wikipedia.org/wiki/%C3%96tztal_Alps#Passes https://en.wikipedia.org/wiki/%C3%96tztal_Alps#Passes).

Quite a lot of traffic would be funneled through a narrow geographic area, especially when considered over hundreds or thousands of years.
