Built between 1825 and 1827, it is a standard mitered-gate lock with a rectangular chamber 90 feet long and 15 feet wide, built of cut sandstone. Around 1905 the masonry was repaired with concrete, and some of that repair has since chipped away. Both gates are gone, though water still stands in the chamber. Thickets have almost hidden the lock in an overgrown stretch of the canal. It sits along a private road that follows the old towpath and leads to a recent private residence. The name probably comes from an incident similar to the one behind the \"Johnny Cake Lock,\" about 1.5 miles north at Everett. The lock is part of the Ohio and Erie Canal, which reviewers described as important in regional development, and it has been recorded as a historic civil engineering landmark by the Ohio Council of the American Society of Civil Engineers.","period_of_significance":"1825-1827","architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Condition fair; sandstone chamber repaired with concrete around 1905, some now chipped away; both gates missing; water in the chamber; heavily overgrown with thickets.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:12.524562-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/79000302.pdf"},"photo":null,"district":{"nrhp_refnum":"85001123","name":"Valley Railway Historic District","url":"https://nationalhistoricalregister.com/districts/ohio/valley-railway-historic-district-85001123/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71986302","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q97994273"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/summit-county/lock-no-26-79000302/"}
