Topographic map courtesy of Dr. J. Bret Bennington of the Hofstra University Geology Department. "The route selected [for the canal] begins at Cornell Basin of the Jamaica Bay channel, bending westerly across the ridge between the creek and the next valley to the west, crosses the Ridgewood acqueduct west of Three-mile Milroad, and Rockaway Boulevard about a quarter of a mile west of the junction with Rockaway Road, then follows the natural valley through the present farms, crossing Hawtree Creek road near its junction with Lincoln Avenue, and Libery Avenue just east of Van Wyck Avenue. From Liberty Avenue the line runs just east of Van Wyck Avenue and nearly parallel to it, following the natural depression to the railroad. It crosses the railroad just east of Dunton Station, thence northerly to the Maple Grove Cemetery property, crosses the summit of the main ridge in the cemetery, crosses Queens Boulevard, and thence down the ravine across the Union Turnpike to the meadows at the head of Flushing Creek to the 200 foot channel planned by the United states Government, and follows this channel to Flushing Bay."
