Pictured: Two bear cubs cling to their mother's back as they hitch a ride across a wide river.   The six month old grizzlies hold on tightly as their mum crosses the fast flowing, 6ft deep water, as they are not yet strong enough to swim and their mother is trying to teach them not to be afraid of cold water.<br />
<br />
The images were captured by photographer Pattie Walsh in Lake Clark National Park, Alaska.   Mrs Walsh, who lives in Gilbert, Arizona, said: "The cubs appeared to be a little apprehensive. They stayed close to their mum and latched on as tight as they could.   SEE OUR COPY FOR DETAILS<br />
