FORMER OKEMOS MAN FEATURED IN MAGAZINE STORY

Okemos, August 10 - A former Okemos man, Lee Glassbrook, is one of the Death Valley park rangers featured in an article, "Death Lurks in the Desert," in this week's Saturday Evening Post.

Andrew Hamilton, the writer, tells of going with Ranger Glassbrook on patrol duty at Towne's pass and Emigrant canyon, which in pioneer days were ill fated for many parties crossing the desert.  Glassbrook's duties are to assist stranded motorists, to caution the tourists about the hazards of desert travel, give instructions as to proper methods of driving along the hot highways or climbing the grades.  A picture shows him assisting stalled motorists, a task he often encounters.

Before being a ranger in Death Valley, Glassbrook had a post in Petrified Forest National Monument, Arizona.  Twenty-two men patrol the valley through which 72,000 visitors drove last year in the four summer months.  Their families live in Wildrose canyon during the hot season.

Glassbrook, a graduate of the Okemos high school and the forestry school of Michigan State university, is the son of Mrs. William O'Carroll, 809 E. Cavanaugh rd., Lansing.

Lee died 10 October 1978, Tulare County, California.  He was interred Exeter District Cemetery, Exeter, Tulare County.  His tombstone is engraved, "An inquiring mind is eternal."
