MONTROSE, Colo. – Medical examiners in Montrose County are trying to determine the cause of a Lakewood woman’s death in Black Canyon National Park Monday.
Tracey Lister, 49, was hiking on the Gunnison route in the park with her two sons – ages 16 and 20 – when she suddenly collapsed.
One son hiked out for help while the other stayed with her. When rangers arrived on the scene, the woman had no pulse, according to a news release.
A fire helicopter was used to recover the body. The incident is under investigation by the National Park Service and the Montrose County Sheriff’s Office.
Although the circumstances that led up to her death are not known, the incident prompted rangers to remind visitors to be mindful of the extreme temperatures and to carry plenty of water.
Black Canyon National Park is located about 10 miles east of Montrose in western Colorado.
