Glenoma is a small unincorporated community in Lewis County between Morton and Randle along Highway 12 at the upper end of Riffe Lake. Its name is derived from the words "Glen" (meaning Fruitful Valley) and "ome" (meaning a measure of grain in Hebrew).
Protecting the population of roughly 1000 within the 12 square mile area are the members of Lewis County Fire District #18 which was established in 1975. Composed strictly of volunteers they are an active part of their community.
2016 was the 100th anniversary of the National Park Service, and to celebrate, Visit Rainier and WSGA hosted the Visit Rainier Centennial GeoTour - 100 caches placed in and around Mount Rainier National Park. The geocaches highlighted the rich history, scenic wonders, quaint communities, and hidden gems of the Rainier region. Participants received geocoin and pathtag prizes for finding all the caches.
