In 1811 David Thompson reported seeing mammoth tracks near the Athabasca river.

I take a look before stepping outdoors, mainly because sometimes the way is blocked by the furry side of a moose, but you never know, a mammoth in the yard would be interesting for talk around the water cooler. Mammoths would probably eat my vegetable garden even quicker than moose do. Fence? What fence? Tromp! Trample! Stamp! Slurp! Mmmmm, fresh cabbages.
