This area of farms is southeast of Morton on Uden Frost Creek. The name was composed by Mrs. Beverly W. Coiner, a settler who later lived in Tacoma. She used glen for the valley, and the Greek word oma for fruitful; hence, fruitful valley. Earlier names, for which no source has been found, were Vern and Verndale.
By the 1940s the town consisted of a cluster of houses, brick and frame, gray school buildings, and a State Highway Department depot. The community depended for its existence upon marginal land farming, from which most of the inhabitants of the region gained their subsistence, and upon small-scale logging operations.
