Meet Katie, one of the 40 million people who depend on the Colorado River. Pondering life after high school, Katie finds comfort in reflecting on her time in one of the Nation’s most iconic National Parks.

The influence of climate change on migratory ungulates of the Rocky Mountains remains uncertain. As climate change leads to advancing phenology, trophic mismatches can occur when migratory individuals arrive on summer range behind the optimal phenological stage of their food resources.

This video was edited and compiled from raw footage recorded by a camera equipped radio collar that was put on a female polar bear in the Beaufort Sea during April 2014 by the US Geological Survey. This new type of camera technology was developed by videographer Adam Ravetch with the support of the World Wildlife Fund.
