Who was Josie Bassett Morris?

Josie Bassett Morris built a homestead in 1913 in Cub Creek. Here she build a cabin and lived on the homestead for over 50 years mostly by herself until the ripe age of 90. Growing up in Brown Park (John Jarvie Trail) Josie and her family became friends with many outlaws including Butch Cassidy and the Sundance Kid. Those friendships continued into adulthood. 

During the prohibition, Josie brewed apricot brandy and chokecherry wine. She was tried and acquitted twice for cattle rustling and murder but was never convicted. 

Josie was married five times and she divorced four husbands in a time when divorce was almost unheard of. Josie's strong will, charm, and independence, garnered rumors about her throughout most of her life. However, Josie was universally admired for living such a remote and rugged lifestyle.


Josie died from complications of a broken hip in May 1964.
