Dennis Hill locality (Litchfield sodalite locality), Litchfield, Kennebec Co., Maine, USA

Nepheline-syenite deposit. Also known as Litchfield Sodalite Locality. The locality was discovered at least by 1845 and chemical analyses of the mineral were published by Charles Jackson although he confused which minerals were reported. This is the locality where historical specimens of cancrinite and sodalite from Litchfield are known. It is also the type locality for hydronephelite, also called "white sodalite", now known as a mixture. Most of the specimens are found in float boulders and not in place. Finds extend into West Gardiner.
