City photographers have known for years the magic that that sub-freezing temperatures can work on flowing water, and have famously chronicled it with stunning photos.
This fountain commemorates Josephine Shaw Lowell, who founded the Charity Organization Society.
Josephine Lowell started her volunteer service at the beginning of the Civil War and, throughout the years, participated in and helped to found many charities. Later Josephine Shaw became the first female member of the New York State Board of Charities, serving from 1876 to 1889.
When the temperatures drop below 30 degrees, the water spilling over the edge of the fountain begins to crystallize.
The fountain is switched off during extended cold spells to prevent enough ice gathering to cause structural damage.
