AUSTIN, Texas -- A legally blind 15-year-old pole vaulter cleared three heights at the Texas state championship but failed to win a medal.

Charlotte Brown of rural Emory Rains High School was one of the top qualifiers in girls' Class 3A with a height of 11 feet, 6 inches. Her best vault of Saturday's final was 10-6 and she missed on three chances at 11-0 before leaving the track to a standing ovation from several hundred people watching her event.

Brown was born with normal vision but developed problems while an infant. She has no depth perception, sees no color and cannot distinguish shapes. Her range of vision is similar to looking through a tiny straw. She reads Braille and will get a seeing eye dog next month.

Also Saturday, 17-year-old legally blind vaulter Aria Ottmueller was scheduled to compete in the Arizona state meet.
