ISLE ROYALE NATIONAL PARK, Mich. — Rolf Peterson, the Michigan Tech researcher who has spent the last half-century studying moose and wolves on Isle Royale, has documented one of the oldest wild moose on record.
Moose No. 5462 was 22 years old when she finally died, definitely a new age record for Isle Royale moose and maybe anywhere where moose roam.
Peterson, who spent parts of the last five years aging more than 400 moose skeletons, said the old cow was "a museum of pathology, with arthritis in 16 of her vertebrae, infections in both upper and lower molars and moderate osteoporosis."
