In Central Kenya, northeast of the Rift Valley, there is a tower. It is a monumental granite swell with a crumbling pinnacle that stretches 17,058 feet into the sky. Mt. Kenya, the second tallest peak in Africa, is home to Ngai, the local water god that is said to create the rains. As a result, Ngai and the mountain provide 70% of the nation's water supply, fed by glaciers and annual storms that eddy around this looming rock island. Pete McBride climbed it's false summit with his family when was 9. Returning in 2012 with a group of climbers, he noticed something frightening. It wasn't the same mountain he climbed as a boy.
