This picture was made north of Muncho Lake Provincial Park in northern Britsh Columbia. As you can see, this river has changed its course several times over the years. The former river bed provides lush grazing for moose.
The place where we were standing for this picture has very interesting formations called "hoodoos". These are tall pillars formed when harder rock lies on top of softer rock. Erosion washes away the softer rock except under a few protective capstones which, over time, appear to be placed high atop the pillars. We don't have hoodoos in the Greater Vancouver area because they do not survive the severe earthquakes that occur every 500 years or so.
