Earlier this week, Weather Underground published a fascinating story about wild horses and their dependence on snow for water at high elevations.  They have adapted to the harsh local conditions and have learned to eat snow for their water in the winter months.  They migrate up and down the slopes as the snowpack comes and goes.  I think you will enjoy reading about these mustangs too.  The article is at https://www.wunderground.com/news/wild-montana-mustangs-depend-on-snowpack?__prclt=5U6EZExJ.
