(Yellowstone National Park, WY) -- We're learning a little more information about the death of a Portland man at Yellowstone National Park. Twenty-three-year-old Colin Scott was killed by boiling acidic water back in June when he fell into a hot spring. National Park officials say Scott was walking in the Norris Geyser Basin, looking for a "hot pot" to soak in at the time. A hot pot is extremely hot, natural spring water. The details were released after a news station in Billings, Montana, filed a Freedom of Information request.
