A 13-year-old home-schooled youth from Minnesota won the 2005 National Geographic Bee on Wednesday.
Nathaniel Cornelius topped young people from across the nation to win a $25,000 college scholarship.
The winning question: "Lake Gatun, an artificial lake that constitutes part of the Panama Canal system, was created by damming which river?"
The answer: Chagres River.
Cornelius, of Cottonwood, represented the Marshall Area Home Educators Association. In addition to knowing his way around, he plays piano and classical guitar and enjoys photography. He also represented Minnesota in the 2003 and 2004 National Geographic Bees.
