As an Algonquin Elder Skip Ross had intimate knowledge of the natural settings of large parts of the Ottawa River Watershed. In June, 2011, at the invitation of archaeologist Paul Thibadeau, Skip and some of his close friends from as far away as Walpole Island travelled to Casselman, Ontario to conduct ceremony at an archaeological site with karst topography within part of the Casselman Cave complex, a provincially significant earth science ANSI (Area of Natural and Scientific Interest). Elder Ross smudged the site, the archaeologists, the archaeologists' tools and the ancient artifacts retrieved at the site. He offered prayers for the ancient ancestors who had occupied the site milleania ago and noted that in a depression at the edge of the site was a thriving thicket of sumac, a wood traditionally used for pipe stems. He named the site "Wimbabika", a word in Anishinaabemowin which means "there is a hollow in a rock, cave, cavern, grotto" (Baraga, 1880).
