Banff Cave and Basin National Historic Site

The historic 1883 Banff Cave and Basin site is the seed that created Banff National Park. I took this picture using a 10mm wide angle lens, and a long shutter speed of 5 seconds at iso 200. The exposure helped bring out the orange layers of tuff on the walls, and the greenish hue of the thermal spring waters. I wanted an image that showed the cave in it's natural form with no human-made objects. The light on the left side of the rocks is from the small opening in the cave ceiling. A beautiful site worthy of a visit if you are in the area.
