Street View update maps North America's biggest parks and monuments

Google's Street View may have already taken us on a virtual tour of some US national parks, but its total number of natural sites now sits at an impressive 44 US and Canadian locations. With permission from the US National Park Service and Parks Canada, the search giant's cars, trikes and backpack-worn Trekker units have mapped some of most picturesque and historical sites in North America, providing us with new 360-degree views of Mount Rushmore, the Alamo Mission in Texas and the crystal-clear lakes of Banff National Park, to name but a few. All of these different locations -- with multiple trails -- are online now and you can check them out by hitting the source below.
