DescriptionMilk River is on the east side of Milk River Ridge, an area more than 1,200 metres (3,900 ft.) high, 39 kilometres (24 mi.) long and 29 kilometres (18 mi.) wide. Quartzite, granite and gneiss rock formations indicate prehistoric glacial action; meltwater carved the Milk River Valley 10,000 years ago. The river, formed from small streams and springs in southwest Alberta and northern Montana, joins the Missouri and Mississippi rivers to flow to the Gulf of Mexico.
Throughout the area and predominantly in Writing-on-Stone Provincial Park/Áísínai'pi National Historic Site are mushroom-shaped sandstone hoodoos, odd rock formations that once led First Nations people to believe spirits inhabited the valley.
