Earlier this year, Facebook co-founder and CEO Mark Zuckerberg declared a personal challenge "to have visited and met people in every state in the US by the end of the year." This weekend, his journey finally brought him to Big Sky Country.

"The impact of global warming is very clear at Glacier. Zuckerberg says he wants people to take care of the environment so parks like Glacier are around for future generations," KULR8 News reports.

The report goes on to say that Zuckerberg visited the Blackfeet Tribe in Browning, and talked about them living on the land for 1,000 years. He posted some impacting photos on Facebook, of course...

One of my favorite photos is of him and Gracie from Glacier, the "Bark Ranger." So cute! She's a wildlife service dog up there. He just got done visiting North Dakota, wonder where he is off to next? Maybe Idaho...
