The Massa Tunnel was dug in the 1850’s on Massa Brothers' land. The tunnel extends 126’ into the east vein of the Mother Lode. Little gold was found. The Kennedy Mine acquired the property in 1898. It and the Argonaut mined the richer west vein until 1942.

Marker can be reached from North Main Street/Jackson Gate Road.
