Got some beautiful weather for a long weekend on the Milk River in Alberta.
This river originates in Montana, flows into the far southern end of Alberta before going back into Montana. The section we floated consisted of prairie grass and farmlands and some badlands and hoodoos. Looking at the topo map of the section downstream of our trip shows a very isolated route with dramatic topography that is probably well worth the effort of dealing with border staff in advance to complete.
But on to my trip...
We floated from the town of Milk River, AB to Writing on Stone Provincial Park, 73km away. The river is a pretty gentle float. The most we encountered was maybe II+, buy my research says some rapids occasionally reach III. Rapids are generally characterized by boulder gardens. Because of the colour of the river, it's often difficult to see all the hazards, but in a raft it's not much of an issue as you'll just bounce off or float around any obstacles. But while most of the submerged rocks seemed to be rounded off granite that poses no threat to a raft, there was the occasional jagged piece of sandstone observed, that could pose more of a problem.
Here's some pics:
