I tried to access the spring by a formerly-published route but found it blocked off my private property. A local jogger clued me into a nearby marina that rents canoes. I will investigate the next time I'm in the area.
I was informed by a local neighbor that the spring is on property owned by a "CP Talyor", undergoing treatment for leukemia. I was told I could write (119 Norton's Fish Camp Road) or call to gain permission.
