Not a Colorado water story but a great series of photographs of a beautiful lake and cave system in Chile. From the article:
To reach this remote place located in the far southern tip of Chile visitors must fly from the capital, Santiago, 800 miles to the next nearest large city, Coyhaique, and then drive on challenging dirt roads 200 miles south to the lake. Yet photography students have travelled the world to learn from Ms Waidehofer about light in what could be the world’s most astonishing classroom. ‘Since 2003 I have taken many photography students into the caverns and it is always the highlight of their South American voyage,’ [landscape photographer and environmentalist, Linde Waidehofer, 67, from Colorado, USA] said.
