An Arkansas woman has died in Oklahoma while helping lead teenagers in a re-enactment of the westward journey of Mormons to Utah.

A spokeswoman for the Rogers, Arkansas, Stake of The Church of Jesus Christ of Latter-Day Saints says 29-year-old Meaghan Lee Querry Blair of Rogers died Monday of what appeared to be heat stroke.

Deborah Neria told reporters that Blair became ill Monday near the end of a 7-mile hike near Tulsa. She was taken to a Tulsa hospital where she died. A phone call to the Rogers office rang unanswered Wednesday.

Blair and her husband were serving as leaders for teenagers on the trek. The groups typically wear pioneer-era clothing, pull handcarts and discuss the mid-1800s Mormons who walked across the Great Plains to Utah.
