Home on the Range on the Alberta/Saskatchewan Border

Today, driving through and beyond Cypress Hill Inter-Provincial Park (we were on the Alberta side, but the park is in Saskatchewan, too), we came across this classic Home on the Range scene:

Horses. White. Brown. Black. White and black. By a watering hole in dry grasses, among gently rolling hills... No, merely gently rolling rises of land.

What is this? A scene with horses grazing on a ranch by a lake in Southern Alberta, under heavy skies... along the Saskatchewan border. 
Location: Near the edge of the West Block, Cypress Hills Inter-Provincial Park (Alberta and Saskatchewan) .
