The Coldest Day of the Year

What do you do on the coldest day of the year.  Of course you bury yourself under blankets with hot drinks and watch movies all day.  That was my plan until I received a text from a friend telling how nice the river looked today.  I couldn't let it pass and bundled up and went to Great Falls National Park to see what the waterfalls looked like on the coldest day of 2015 (until tomorrow).  I'll save you the trouble of braving the cold.
