The name of this postcard is Jamaica Pond, Jamaica Plain. Jamaica Pons is a spring-fed, 90 feet deep kettle hole formed by glacial melt water over 10,000 years ago. Prior to 1630, Jamaica Pond was the summer home of the Mattapan Wampanoags. Between 1795 and 1848, Jamaica Pond supplied most of Boston’s fresh drinking water. And in 1894, the City of Boston purchased the Pond to make it part of the string of parks designed by Frederick Law Olmsted that are now known as the Emerald Necklace.
