Man, 20, who drowned after being sucked into Alaska mud died on summer 'adventure'

A college student died on a summer adventure in Alaska when he got stuck on dangerous mud flats and sucked into the ground.

Zachary Porter, described by his family as a passionate traveller and outdoor enthusiast, found himself trapped in quicksand-like silt on the treacherous Turnagain Arm mud flats.

The 20-year-old from Illinois, a sophomore (second year) at Washington University in St. Louis, had embarked on the Alaskan trip with a group of friends before at the start of summer.
