TULSA, Okla. — An Arkansas woman died Tuesday after participating in a pioneer reenactment activity with other members of her LDS Church congregation.

Meaghan Blair, 29, suffered a heat-related seizure and a spinal cord injury caused by excessive body temperature, according to a Facebook posting made by her sister on Monday.

Sarah Waddoups, a spokeswoman for the Blair family, told FOX 13 the cause of death has not yet been determined.

A statement (below) from The Church of Jesus Christ of Latter-day Saints indicates Blair was serving as a youth leader for a “youth trek activity” near Tulsa, Oklahoma.

Participants in LDS Church treks often dress in pioneer-era clothing and pull heavy handcarts to simulate the experiences of Mormon pioneers who traveled to the Salt Lake Valley in the mid-19th century.
