The Tenino Stone Company Quarry, at City Park in Tenino, Washington, was listed on the National Register of Historic Places (NRHP) in 1983.
The site, officially converted into a community swimming pool by 1950, is a sandstone quarry from which stone was removed in a box shape. Known under other names such as the Memorial Swimming Pool, Quarry Swimming Pool, or the Veteran's Pool, the quarry contains a diving pool and the basin is split into two sections, a shallow area and a deeper pool, large enough to be considered an inland lake.
The quarry opened as early as 1889 [2] and closed in the 1920s after the Tenino Stone Company shuttered in 1918. [3] [4] Abandoned, the area was closed and was deemed a no-trespassing zone. The formation filled with spring water and the quarry became an unofficial pool in the community. [4] [2] [3]
There are two proposed causes to the cavities filling with water - that workers in the quarry opened up a natural spring or that personnel turned the pumps off as they left the job in a labor protest, the quarry naturally filling with water. [4]
The quarry was placed on the National Register of Historic Places in 1983. [5]
Tenino purchased the quarry and surrounding acreage in 1946. The area was officially opened as a pool, known as the Tenino Memorial Pool or the Veteran's Pool, by the city on June 8, 1950. [3] [6] [a] It remained without any significant upgrades until a 2018 renovation project funded in part by a grant of $200,000 from Thurston County. The remodeling was completed in 2023 with the addition of a splash park and a combined retaining wall and walkway, and betterments were completed to the decks, docks, and filtration systems. [7] [8] Further renovations were undertaken into 2024 which included additional safety measures and access for disabled people; a large reopening of the facility was in June 2024 as part of the city's Tenino Family Fun Day event. [3] [6]
Due to the nature of the cold waters and depth of the deeper pool of the quarry, swimmers must have passed a swim test or are required to be 18 years or older. [2]
The box-shaped quarry measures about 900 feet (270 m) long, 60 feet (18 m) wide, and up to 100 feet (30 m) deep. [5] [2] [b] The freshwater temperature averages between 57 °F (14 °C) and 58 °F (14 °C). A waterfall flows over the quarry walls that contains growth of ferns and moss. [2]
The site contains two separate swimming areas. A shallow pool, 2 feet (0.61 m) deep, also contains a spray area. The large pool, used for swimming and diving is measured up to 80 feet (24.4 m) in depth and is deep enough to be considered an inland lake. [7] [5] The site also contains picnic areas and outdoor shower facilities. [6]
