This is a classic Colorado image that I have been wanting to take many times but never hit with the trees in color. There were a bunch of photographers lined up on the rock slide that creates the window. I hoipe they came away with good images. I was quite happy how this turned out even though I forgot my tripod and had to dial up the ISO to take this image. Luckily modern cameras do very well with that.
