Boston CPB/Baptist 26 - U.S. Benchmarks on Waymarking.com

This mark is part of a First-Order Triangulation network set up for the City of Boston by the WPA from 1935-1941. Information on the location was found in Report on a Geodetic Survey for Boston, 1935-1941 (WPA Project Numbers 65-14-5744, 665-14-3-952, 165-1-14-259), published Nov. 1942.

The network consisted of 65 stations spread throughout Boston, spilling into neighboring municipalities. Many of the stations had local transfer triangles, consisting of one or more disks - this disk is not one of the 65 stations, but a transfer point.

The disk is a transfer point for the station BAPTIST. Station BAPTIST, if it still exists, sits atop the New England Baptist Hospital on Parker Hill in Roxbury, Boston, MA.

The aforementioned publication has this to say about the transfer point itself on page 37:

"Ground Transfer Point, 'Baptist' Monument No. 26 - (First order traverse point No. F7/0)
Description: This point consists of a C. P. B. disc set located on the northwest corner of Brookline Avenue and Riverway..."

The text gives specific measurements, but the area has changed significantly since 1938. There is little in the way of landmarks, but the mark is easy to see. It is just northeast of the north corner of Brookline Avenue and the Riverway, across Brookline Ave from the end of Fenwood Road. The mark itself is embedded in the curb.

Table II (p. 176) of the book gives the Massachusetts State Lambert Projection Coordinates (based on the C&GS adjustment, 1941) of this station as (705338.50, 487245.75).

1. A closeup photo of the mark taken by you is required.
2. A 'distant' photo including the mark in the view is highly recommended. Include the compass direction you faced when you took the picture.
