Quick Description: A US C&GS BM embedded in the steps of the Old State House in Boston, MA.
Location: Massachusetts, United States
Date Posted: 3/2/2006 10:41:26 PM
Waymark Code: WM88X
On the North side of the Old State House in Boston, MA, in an area with poor GPS reception, owing to tall buildings. According to the stamping, it is 26.285 feet above sea level.
To reach the station, go to the site of the Boston Massacre, approximately at Devonshire St and Court St. The Freedom Trail will lead you to the south of the Old State House (right to your west). You'll, however, want to walk down Court St (i.e., on the north of the Old State House). In the center of the building (east-west-wise) there are a few steps. The mark is embedded in the NE corner of the first (i.e. lowest) step.
A note about this disk: it seems that there were a series of Tidal BMs placed in Boston with the markings J 12 and K 12 (MY0562 and MY0555, respectively). This one was most likely placed in sequence, but for some reason, was not maintained.
