Talk:Mill Rock

Moved editorial comments
I moved the following text here from the main article. It seems to be editorial in nature, and questions the content of the article. It does reference sources, although ones I do not have easy access to. &mdash; Eoghanacht  talk 19:50, 11 October 2006 (UTC)

"on adjoining Flood Rock" may be misleading in the above paragraph. A page of engravings from Harper's Weekly for December 25, 1880, page 824, shows tunneling operations under Flood Rock preparatory for the blast.

A full page engraving, page 680 pf vol. XXIX, No. 1504 shows the explosion itself from 87th Street, with a crowd of spectators. It does appear to blow up from under water, and must have been a thrilling sight.

Size of Island possibly incorrect
The size of the island is given as 8.6 acres.However, using a website that measure distances and area, it appears the island is more like 2.5 acres. Where is the claim for 8.6 acres based on? Tsivkregal (talk) 19:51, 19 August 2017 (UTC)

identifying Flood Rock
I'm having some trouble matching this article to various old maps available online. There's an app here that overlays a current map of NYC with one made by Joseph Colton in 1836 (s.a. ). That map has only one Mill Island, while according to this article and the NYC Parks source there were two, connected only decades later. Furthermore, using that app, it appears current shape of Mill Island seems to extend to what is on the old map labeled as "Flood Rock", while another charted "Hancock Rock" is neither mentioned in this article nor in the more in-depth Removal of Hell Gate rocks; there's also a "Middle Reef", but only indicated as hatching. Yet another map from 1840 seems to agree with the Colton map about "Flood Rock", but has no "Hancock Rock", and shows more detail of "Middle Reef" as consisting of what I assume are distinct, submerged rocks, or shallows. I wonder if a name shift happened there at some point, identifying, maybe in retrospect, as "Little Mill Island" what was formerly known as "Flood Rock", while the blasting was carried out on the submerged "Middle Reef". -- Theoprakt (talk) 19:23, 19 November 2019 (UTC)
