The subtle blue in this shot is a result of preferential scattering of short-wavelength light as it travels down a long vertical shaft into the cave and hits the waterfall mist in the moonlight. The Natural Bridge is a naturally formed rock arch over Cave Creek, a tributary of the Nerang River. It was formed from a waterfall which undercut a cave beneath the waterfall and dug a pothole on top, until the two joined and the creek flowed through the cave, leaving an arch across the front.

Predawn colour lights up the sky and paints a pink hue over the Murray River as it plunges 70m (229 ft) down the majestic Kinuseo Falls. First documented on a western map in 1906, Samuel Prescott Fay provided the first description of the falls in 1914 as part of a scientific expedition. He named the falls “Kinuseo”, which was fish in the native Cree language, due to the abundance of trout he observed above and below the falls. A second expedition in 1927 recorded “Kapaca Tignapy” as a traditional Cree name for the falls translating as “falling water”. Monkman Provincial Park, Northern Rockies, British Columbia, Canada.
