Poston. Remaining parts include a smoke stack, hoist house, tipple, shower room ruins, hospital ruins and water tank, on a 20.8-acre nominated area.","why_significant":"The nomination presents the mine as representative of the coal boom of the 1920s and 30s in the Hocking Valley and as holding one of the few remaining tipples of that era in the region. It is also the site of the November 5, 1930 explosion that killed 82 men, the largest mine disaster in Ohio. The Hocking Valley was also where the United Mine Workers of America was formed.","narrative":"Near East Millfield in Athens County, Ohio, the remains of the Poston No. 6 mine mark a once-large coal operation built in 1910 or 1911 for Clinton L. Poston and later part of the Sunday Creek Coal Company. Surviving features include a 150-foot brick smoke stack, a brick hoist house, a timber-framed tipple, a water tank and the ruins of a shower room and hospital. The main shaft is capped with concrete, and the mine stopped production in the 1940s. The mine was described as the largest and most fully equipped in the Hocking Valley in its day. It was the site of Ohio's worst mine disaster, when an explosion on November 5, 1930 killed 82 men, including company officials on an inspection tour. The property was listed as a representative example of the region's coal boom, with one of the few tipples of that era left, and for its link to the history of coal mining and the United Mine Workers in the valley.","period_of_significance":"1900- (specific dates 1910-1911)","architect_builder":"Built for Clint Poston","architectural_style":"Hoist house described as common bond brick industrial building with Italianate stylization","criteria":[],"status_note":"Mine shut down in the 1940s; main shaft capped with concrete; several buildings are ruins or no longer standing, and the hospital has lost its roof.","vacant_flag":true,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:09.085927-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/78002005.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71986733","wikipedia":null,"wikidata":null},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/athens-county/sunday-creek-coal-company-mine-no-6-78002005/"}
