A section of the town of East Hampton named for the station stop on the former Air Line Railroad (began 1873) and centered on the intersection of state routes 66 and 151 (coordinates). The station was named for the cobalt mines situated just north of the rail road, at the foot of Great Hill.

Cobalt is known for the minerals from these mines and from some local pegmatites.

Habit: flat prisms with dome terminations
Colour: pale yellow
Description: Specimens analyzed by Leavens, et al. (1978) from New England were analyzed and found to be true hydroxylherderite. As the study was made after the reference cited and as there are only one or two analyzed true herderites in the world, the entry was changed to conform to modern nomenclature. Leavens, et al., 1978, Compositional and Refractive Index Variations of the Herderite-Hydroxyl-herderite Series, American Mineralogist, v 63, p. 913-917. "Chemical analysis of herderite, collected by the author, at the State Forest Mine in East Hampton, Connecticut, indicate that it is the hydroxyl variety" (Januzzi 1994). Described (as herderite) by Schooner (1958) as "twenty five 1/32 inch pale yellow tabular crystals in a vug of albite and altered siderite, near a contact with semi-columnar beryl"

'Limonite'
Formula: (Fe,O,OH,H2O)
Löllingite
Formula: FeAs2
Description: Loellingite is in fact the primary Co-Ni ore of Shepard's and Robert's Lodes. "Shepard [1837] initially identified the Co-Ni bearing arsenide as the cubic di-arsenide, smaltite but after obtaining and studying additional material from his own mine he pronounced it to be a new orthorhombic tri-arsenide for which he proposed the name "Chathamite"....In the mid 1850s Genth (in Goodrich, 1854) questioned Shepard's identification and suggested that Chathamite was simply an iron rich variety of the cubic arsenide chloanthite (a misconception that perpetuated up to, and including, the 7th edition of Dana's Manual of Mineralogy). As it turns out, Shepard's Chathamite is indeed orthorhombic, but today would be classified as a nickel-cobalt rich loellingite." Gray (2005)
Reference: Gray (2005); Chomiak (1989)
Ludlamite
Formula: Fe2+3(PO4)2 · 4H2O

Messelite
Formula: Ca2Fe2+(PO4)2 · 2H2O
Habit: massive curved, lamellar aggregates, acicular microcrystals
Colour: white to tan, sometimes a green coating of an unknown.
Description: "Many solid white or tan masses, with a curved lamellar structure, were collected; some were two inches across. The messelite was intergrown with siderite, or embedded in triphylite. Distinct crystals, with a pearly luster, were noted in vugs of the massive mineral." Schooner (1961). Associated with triphylite, siderite, strunzite, laueite, mitridatite, ludlamite, vivianite. A green mineral thought to be beraunite was tested by XRD (with some matrix) at the National Museum Prague (dr. Jiri Sejkora) and found to be "no beraunite but something similar to messelite". The green may be only a coating.

Nickelskutterudite
Formula: (Ni,Co,Fe)As3
Habit: grains
Description: "Shepard [1837] initially identified the Co-Ni bearing arsenide as the cubic di-arsenide, smaltite but after obtaining and studying additional material from his own mine he pronounced it to be a new orthorhombic tri-arsenide for which he proposed the name "Chathamite"....In the mid 1850s Genth (in Goodrich, 1854) questioned Shepard's identification and suggested that Chathamite was simply an iron rich variety of the cubic arsenide chloanthite (a misconception that perpetuated up to, and including, the 7th edition of Dana's Manual of Mineralogy).

Formula: (Li,Na)2(Sr,Ca)Al4(PO4)4(OH)4
Colour: colorless
Description: "A colorless acicular mineral, found by the author in a vug of messelite, at the State Forest Mine in East Hampton, does not fit the description of any typical species except palermoite. Unfortunately, very little was obtained; an excellent sample was sent away for testing, but was evidently lost" (Schooner 1961). Most likely, this was a very poor guess.

Very few specimens have been found, and they are small; the crystals are green and quite glassy, the largest being about an eighth of an inch in diameter. The author suspected the identity of this material from the time he discovered it, several years ago, but it was not confirmed until recently. Some of the optical data follows: R.

It was first noticed in the dump; a search of the locality soon revealed two small bodies of triphylite in the left hand wall of the open pit, just above the short tunnel. A number of specimens were collected, some being cleavage masses up to four inches wide. Siderite, messelite, ludlamite, and several other typical minerals were intergrown, most of them owing their origin to the hydrothermal alteration of the triphylite. One small crystal was noted."
