<P> Another rare exception occurs when a stream near a divide splits and flows in both directions, or a lake straddling the divide overflows in both directions . Examples of these are, respectively, North Two Ocean Creek and Isa Lake, both located on the Continental Divide in Wyoming . The Panama Canal has this same feature, but is man - made . Both the Chagres and Gatun rivers flow into Gatun Lake, which empties to both oceans . </P> <P> Several small lakes along the Divide in the Rocky Mountains between Alberta and British Columbia flow into both provinces and thus into both Atlantic and Pacific Oceans . An example is the "Committee Punch Bowl", a small lake located in the Athabasca Pass named by Sir George Simpson, governor of the Hudson's Bay Company, while touring his vast Canadian fur - trading empire in 1825 . According to historical sources, "The small circular basin of water at the summit, twenty yards in diameter, is dignified with the name of the' Committee's Punch Bowl' in honour of which the Governor treated them (his fur traders) to a bottle of wine as they had' neither time nor convenience to make a bowl of punch, although a glass of it would have been acceptable ."' The reference is to the governing committee of the Hudson's Bay Company in London, England . </P> <P> The Alpine Club of Canada's Abbot Pass Hut sits directly astride the Divide in Abbot Pass on the boundary between Banff National Park and Yoho National Park, and thus rainwater falling on the eastern half of the roof flows via Lake Louise into Hudson Bay, while rain falling on the western half flows via Lake O'Hara into the Pacific Ocean . </P>

Is the continental divide man made or natural
