I recently spent some time at the Grasslands National Park in Val Marie, Saskatchewan. Possessing a unique ecosystem that supports three hundred head of plains bison, prairie dogs, coyotes, pronghorn deer, rattlesnakes and a multitude of birds; the park is a well-kept secret worth visiting. The flat prairie scenery gives way to an incredible maze of hills and valleys shaped by glacial meltwater. In 1877,  Sitting Bull and five thousand of his Sioux warriors took refuge here after defeating Custer at the battle of Little Bighorn. 
The highlight of the trip, camping in the backcountry and waking up at 5:30 am to grazing Bison.
