Camp Bonneville, near Vancouver, Washington, began in 1909 as a United States Army post used as a rifle range and weapons training facility for troops from Fort Vancouver. For several years it also hosted students in outdoor education programs run by local school districts. The four thousand-acre property was later recommended for closure by the 1995 Base Realignment and Closure Commission and transferred to Clark County for conversion into a public park. That plan was disrupted when cleanup, begun in the late 2000s, stopped after toxic chemicals from military use, including RDX and perchlorate, were found on the site.
