Claytonia is an unincorporated community in Owyhee County in the southwestern part of the U.S. state of Idaho.[1]
The community is located less than 2 mi (3.2 km) northwest of Marsing and 13 mi (21 km) west of Nampa.[2] The Snake River flows east of the settlement.
Claytonia was named for an early resident.[3]
Irrigation was brought to the area in 1913, and settlement followed. Many stores were opened in the area, though only the store in Claytonia "stayed open for a decent amount of time".[3]
A post office operated in Claytonia from 1914 to 1918.[4]
Claytonia was a station along the "Homedale, Idaho" branch of the Union Pacific Railroad. The line is now abandoned.[5][6] The railway operated a gravel pit in Claytonia, with the gravel used for track construction.[6] The gravel pit was abandoned, and later reclaimed as a recreational area filled with ground and ditch water, and called Claytonia Pond. The pond is used as a fish habitat, and contains catfish, bluegill, and largemouth bass.[7]
