A couple weeks ago while I was poking around down at the Snye, I came across a cairn denoting one end of the Methye Portage, an old transportation route linking the Athabasca River to Lac La Loche, across the border in Saskatchewan via the Clearwater. After posting a photo of the cairn on my blog here, on commenter mentioned that this was one of three such cairns, dating from the 1930's. Another important cairn (pictured below) can be found just inside the treeline at the edge of the parking lot at MacDonald Island. It commemorates the signing of Treaty 8 on August 4, 1899. A third cairn, which is a little more tricky to get to can be found a few hundred kilometres north in the community of Fort Chipewyan.
