Seton Portage
Seton Portage is an historic rural community in British Columbia, Canada, that is about west of Lillooet, located between Seton Lake and Anderson Lake. "The Portage" was formed about 10,000 years ago when the flank of the Cayoosh Range, which is the south flank of the valley, let go and slid into the middle of what had been a single lake.〔(Seton Portage.ca website )〕 The result is a location similar to Interlaken, Switzerland, with two fjord-style lakes flanking a narrow and very short strip of land between them.
There are two First Nations communities, comprising several individual Indian reserves of the Seton Lake First Nation, at either end of the Portage, with the intervening area and some of the Anderson Lake shoreline taken up by a small non-native recreational community, including a couple of orchards and small farms. There are two motels, a store, a provincial park campground and heritage site, and a pub.
==Origin of the Portage==
Remnants of old lake bottom survive as benchlands lining the north banks of Seton and Anderson Lakes. It may be that the glacial moraine at the foot of Seton Lake, which had been at the foot of the Seton Glacier and, after it melted, dammed the older, larger lake in until the slide and its destructive wave (see megatsunami). The inundation then washed part of it away to open Seton Creek and drain the glacial melt to today's lake level, or close to it (since the lake level is 10–12 feet higher because of the power project completed in 1958).
