Of all the thousands of mountains in the Rocky Mountain area of Alberta, Canada, Castle Mountain has always been my favourite. Every time I see it, there seems to be a different perspective! On this trip, we saw it shrouded in rain and mist, and also with this backdrop of blue sky, white clouds and the shimmering turquoise of the river. The mountain is at the southern end of Banff National Park. Taken during our Second Red Bubble Meet N Greet which was held just down the road in Canmore, Alberta. June 23-25, 2011.
