"Happening Now" co-host Jon Scott got back last week from a once-in-a-lifetime journey, as he trekked to Tanzania to climb Mt. Kilimanjaro for a great cause. 

Jon was able to raise more than $6,000 to support Compassion International, a Christian charity that supports efforts to provide clean water to African children. (Learn more, here.)

On the show today, we saw two videos showing Jon's amazing ascent. He explained that even though it's not a technical climb (no ropes or ice axes needed), the journey can be deadly. 

About 10 people die each year on the climb, usually from heart attacks or the extreme altitude. 

It was 15 degrees Fahrenheit when he and his group reached the summit.

After about 15 minutes of taking it all in, it was time for an arduous hike back down the mountain, a 14-mile trek that ended in a tropical rainforest. 

He explained that he was reminded about the purpose of his journey throughout, since each person was drinking 3 to 4 liters of water a day.

"For millions in Africa, drinking water is pulled from a stream or a smelly surface pool. You and I would never consider this drinkable. They don't have a choice."

Jon was tweeting throughout his incredible trip. Take a look at the photo album we put together last week, and watch the highlight videos below:
