-------- Original Message -------- Subject: Lookin for maps of San Juan, PR - 1805 to 1851 Date: Tue, 17 Jul 2012 15:45:28 -0400 From: Thornberry, Evan <[log in to unmask]> To: Maps, Air Photo, GIS Forum - Map Librarianship ([log in to unmask]) <[log in to unmask]> Hi all, I have a patron interested in maps of San Juan, Puerto Rico from 1805 to 1851. She is trying to determine the dates of construction of the Miraflores Canal which separates Miraflores Island from the mainland. The earliest map we have found showing the canal is located in David Rumsey’s collection from 1851 (http://www.davidrumsey.com/luna/servlet/s/z9i6bb (located in the San Juan inset map)). Any information, maps or otherwise, on the topic of the canal’s construction is appreciated. Nuestro españolesun poco malo.
