    1969: Niagara Falls runs dry

    From Mashable.com:

    For several months in 1969, the torrent of water rushing over American Falls, one of three waterfalls that makes up Niagara Falls, was reduced to little more than a trickle.
    American Falls is recognizable for the immense rock pile, or talus, at its base, the result of a series of natural rockslides over the years. In the late 1960s, concerns were growing that further rockslides could erode the falls completely.
    To study the geological composition of the falls and forestall their potential destruction, a joint American-Canadian commission decided to dewater them for five months.
    Over three days in June 1969, more than 1,200 trucks dumped nearly 28,000 tons of rocky fill into a cofferdam upstream of the falls, diverting the flow of the Niagara River away from American Falls and toward the much larger Horseshoe Falls.
    With the falls dry for the first time in millennia, the US Army Corps of Engineers began their investigation.

    Top 10 Canadian places featured on Instagram: From Vancouver International Airport to Niagara Falls

    From the National Post:

    Instagram recently revealed its list of the top places in Canada featured in Instagram photos this year. Given the size of the population (and some of the events going on this year), it’s not surprising that southern Ontario holds down seven of the top spots. You’ll also find British Columbia and Montreal. Here’s the list.

    1. Niagara Falls. One of the most photographed places in the world, Niagara Falls has been attracting tourists for centuries. You’ll get great shots from the boat rides below the falls with Hornblower Cruises, or you can try something in winter or at night with the floodlights on. Also worth trying is the Journey Behind the Falls, where you can take an elevator deep inside the rock behind the falls and also clamber out onto a platform for nice viewing.
