O.k., I'm in!
A shadow contest hey!?! Alright, last summer as I was chasing rainbows near Jasper Village, in the National Park, a series of rain clouds came by during the sunset. The sun casted the shadows of the mountains on the rain while the upper part of these continuously morphing shadows were shinning with a rainbow hue!!! With a bit of imagination, you will even notice an eagle that had formed in the shadow of the mountain, just left of the center point... ;)
I hope you all enjoy! Namaste :)
