Not long ago, ecologist and climate change scientist Jane Zelikova and a friend grabbed a camera and went on a mission. They wanted to know what was really happening with snowpack in the Rockies and what to expect in the future. Their short film, "The End of Snow,"  is out now. She tells Colorado Matters that her PhD at CU Boulder focused on the Tropics, but for her post-doctoral work she wanted to turn her attention to Colorado, Wyoming and Utah -- where  changes were happening in her own backyard.
