Sherman Shoemaker, 11 The U.S. Forest Service calls the monument âthe pivotal attraction of the Mitchell Recreation Area.â The stone memorial is surrounded by picnic tables and fire grills. Thereâs also the âShrapnel Tree,â a Ponderosa pine that bears scars from the long-ago bomb explosion and in 2005 was designated an Oregon Heritage Tree. Elsie Mitchellâs parents attended the monumentâs 1950 dedication, but their son-in-law wasnât able to do so. He was in Vietnam spreading the gospel. In 1962, he and two other Christian missionaries were kidnapped by the Viet Cong and disappeared. Itâs not known what became of them.
