It was built in approximately 1840 by Colonel Anthony Kleckner.","why_significant":"The nomination argues the mill is significant as a well-preserved water-powered grist mill, retaining much of its original machinery, much of it handmade wooden equipment and leather belts. It is described as the only remaining grist mill in the area with much of its original equipment. It was also presented as a former center of local business and political life, at a time when grist mills were the largest individual business operations in the region.","narrative":"Logan Mills, on the banks of Fishing Creek in Clinton County, Pennsylvania, is the site of a three and one half story coursed stone grist mill built about 1840 by Colonel Anthony Kleckner. Water was diverted from the creek through a race into the basement, where two turbine wheels drove the milling machinery. The building has a tin covered gable roof, three bays by four bays, with 6 over 6 windows on the second story and 8 over 12 windows on the third. Three loading doors in the east gable end were served by a pulley over the third floor doorway, and a one story stone addition stands on the north elevation. Power was transmitted through wooden gears and leather belts, many of which survive. The mill is regarded as an outstanding example of pioneer craftsmanship, and it is notable as the only remaining grist mill in the area with much of its original equipment. Before the iron furnace, grist mills were the largest individual businesses in the region, and this one also served as a center of local commerce and politics. The dated machinery includes grinders from 1883 and dressing machines from 1888.","period_of_significance":"1840","architect_builder":"Colonel Anthony Kleckner (builder)","architectural_style":null,"criteria":[],"status_note":"The mill is in excellent condition and most of its original machinery remains in place and in operating condition.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:33.415225-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/80003476.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80003476/b484a45239-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80003476/b484a45239-1600.webp","licence":"CC BY-SA 3.0","author":"Ruhrfisch","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Clinton_County_NRHP_007.JPG\" rel=\"noopener\">Ruhrfisch</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Clinton_County_NRHP_007.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996303","wikipedia":"https://en.wikipedia.org/wiki/Logan_Mills_Gristmill","wikidata":"https://www.wikidata.org/wiki/Q6667104"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/clinton-county/logan-mills-gristmill-80003476/"}
