An elongated hill measuring about 1 mile N-S and 0.4 mile E-W. It is bordered by Rose Hill Road and Collins Hill Road along its western base, and by Carr Brook to the north and east. The base elevation is about 150 feet above sea level, while the summit elevation is over 350 feet. The hill is mostly underlain by the Ordovician Collins Hill Formation (formerly called the Bolton Schist), which is mostly schist with calc-silicate layers and minor marble and quartzite. Along the base of the west flank is some Devonian Maromas Granite Gneiss and Ordovician Glastonbury Gneiss underlies the eastern flank. Granite pegmatites crop out in several places, most notably the Strickland Pegmatite, which was mined and quarried by the Schoonmaker Mine and Strickland Quarry for decades. Besides the pegmatite minerals, the mineralogy of the metamorphic rocks includes kyanite, staurolite, sillimanite, ilmenite, schorl, micas, hornblende, pyrite, pyrrhotite, and calc-silicate minerals such as epidote, diopside, actinolite, and grossular. The latter are found around the pegmatite and at the waterfall along Carr Brook at the northern end of the hill. The mineralogy is discussed in detail in the sublocalities. Coordinates are for the summit.

Aragonite
Formula: CaCO3
Arsenolite ?
Formula: As2O3
Habit: powder
Colour: yellowish
Description: Schooner (1955): "as yellowish powdery incrustations on decomposed arsenopyrite at the Strickland Quarry. One rather large mass of the unusual material was taken out of the pegmatite which adjoins the schist in the cut above the main pit. Pyrite is associated, in all the specimens."
Reference: Schooner, Richard. (1955): 90 Minerals from 1 Connecticut Hill. Rocks & Minerals: 30(7-8): 351-8.
Arsenopyrite
Formula: FeAsS
Description: Schooner (1955): "crystals, of the finest quality, though of small size, are rarely collected from the pegmatite at the Strickland Quarry. The author has several specimens, showing the mineral in a variety of matrices, and he saw the remains of a 1 inch crystal, in the wall of the aforementioned cut." Schooner (circa 1985): "Excellent little crystals are rarely found at the Strickland quarry, either isolated or with sphalerite and pyrite. A few 1/2 inch rough crystals were embedded in the interior of a large pseudomorph of muscovite after schorl."

Colour: gray
Description: Specimens of metasomatically altered natromontebrasite, collected at the Strickland quarry around 1950 by Charles Thomas, consist of gray augelite crystals intergrown with pink brazilianite, pink hydroxylapatite, and yellow lacroixite. Very little such material was preserved, and most of it was consumed in study at the U.S. Geological Survey. Natromontebrasite was discredited in 2007, being a mixture of montebrasite, lacroixite, and wardite.
Reference: Schooner, Richard. (circa 1985) Untitled manuscript on central Connecticut mineralogy.; Handbook of Mineralogy (http://www.handbookofmineralogy.org/pdfs/lacroixite.pdf)
Augite
Formula: (CaxMgyFez)(Mgy1Fez1)Si2O6
Habit: massive granular
Colour: brown
Description: "A striking brown clinopyroxene, with a silky luster, collected at the Strickland quarry, gives an X-ray pattern closer to fassaite than diopside or augite. As learned from similar material, at the railroad cut two miles west, the surficial alteration is a smectite, corroborating the aluminum content. Fassaite also accompanies zoisite, quite abundantly, at ledges immediately west of the Strickland quarry." Schooner (circa 1985).
Reference: Schooner, Richard. (circa 1985), Untitled manuscript on central Connecticut mineralogy.
Augite var: Fassaite
Formula: (Ca,Na)(Mg,Fe2+,Al,Fe3+,Ti)[(Si,Al)2O6]
Habit: massive granular
Colour: brown
Description: "A striking brown clinopyroxene, with a silky luster, collected at the Strickland quarry, gives an X-ray pattern closer to fassaite than diopside or augite. As learned from similar material, at the railroad cut two miles west, the surficial alteration is a smectite, corroborating the aluminum content. Fassaite also accompanies zoisite, quite abundantly, at ledges immediately west of the Strickland quarry." Schooner (circa 1985).
Reference: Schooner, Richard. (circa 1985), Untitled manuscript on central Connecticut mineralogy.
Autunite
Formula: Ca(UO2)2(PO4)2 · 11H2O
Habit: tabular flakes, coatings
Colour: pale yellow
Fluorescence: bright green
Description: Should be referred to as meta-autunite as all such material is dehydrated. Associated with uraninite and uranophane.
Reference: Schooner, Richard. (1955): 90 Minerals from 1 Connecticut Hill. Rocks & Minerals: 30(7-8): 351-8.
Bavenite

Formula: Be3Al2Si6O18
Beryl var: Heliodor
Formula: Be3Al2(Si6O18)
Beryl var: Morganite
Formula: Be3Al2(Si6O18)
Bismite
Formula: Bi2O3
Description: Schooner (1955) only says it was reported "many years ago". With no bismuthinite present its presence is dubious or confusion with specimens from the nearby older Pelton Quarry.
Reference: Schooner, Richard. (1955): 90 Minerals from 1 Connecticut Hill. Rocks & Minerals: 30(7-8): 351-8.
Bismuthinite
Formula: Bi2S3
Description: "Not seen" by Schooner (1955). Schairer (1931) seems to be the source of all later repetition, and he said it was found "very rarely" in Portland. This generic reference probably means the much older Pelton Quarry where it is well known.
Reference: Schooner, Richard. (1955): 90 Minerals from 1 Connecticut Hill. Rocks & Minerals: 30(7-8): 351-8.; Schairer, J. F. (1931): The Minerals of Connecticut. State Geological and Natural History Survey Bulletin 51.
Bismutite
Formula: (BiO)2CO3
Description: Early references such as Schairer (1931) only attribute the mineral to "Portland" and this could easily mean the older Pelton Quarry where it is known. Schooner (1958) says: "The Wesleyan University collection...contains a solid two inch mass of the mineral from Portland. The exact source may have been the Strickland Quarry, though it is not specified on the label". Nope, that piece is from the Pelton Quarry as described in Wells, H. L. (1887), Bismutosphaerite from Willimantic and Portland. American Journal of Science: s. 3, 34: 271-4.

Bityite
Formula: LiCaAl2(AlBeSi2O10)(OH)2
Habit: hexagonal
Colour: white
Description: Schooner (circa 1985) says: "When the Strickland quarry was last active, the author found a boulder of cleavelandite with a small vug of aggregated lustrous white hexagonal-looking crystals with calcite and a trace of lepidolite. It was many years before the mineral was recognized as being a mica! Its unusual X-ray pattern aroused some curiosity, and it was forwarded to Pete J. Dunn at the Smithsonian. He identified it as bityite, and made an analysis by electron microprobe."
Reference: Schooner, Richard. (circa 1985), Untitled manuscript on central Connecticut mineralogy.
Brazilianite
Formula: NaAl3(PO4)2(OH)4
Colour: pink
Description: Schooner (circa 1985) says: "A few masses of Strickland quarry natromontebrasite, from the pollucite zone in the middle eastern wall, halfway down, are composed of intergrown metasomatic or hydrothermal alterations. Pink brazilianite, containing a trace of Mn (analysis by the USGS), is associated with augelite, lacroixite, and hydroxylapatite. This mineral was collected by Charles Thomas, and studied by Mary E. Mrose. Ronald E. Januzzi had earlier collected material, on the old dumps, in which the brazilianite occurs as confused white aggregates, with hydroxylapatite and possibly morinite." Natromontebrasite was discredited in 2007, being a mixture of montebrasite, lacroixite, and wardite.
Reference: Schooner, Richard. (circa 1985) Untitled manuscript on central Connecticut mineralogy.; Handbook of Mineralogy (http://www.handbookofmineralogy.org/pdfs/lacroixite.pdf)

Cassiterite
Formula: SnO2
Habit: twinned bipyramids
Colour: deep red-black to dark brown
Description: Tiny, dark, lustrous, sharp crystals typically embedded in lepidolite or spodumene with K-rich albite. Can easily be confused with tantalite-(Mn) or wodginite, though these minerals are differentiated from it by their strong iridescence.
Reference: Schooner, Richard. (circa 1985), Untitled manuscript on central Connecticut mineralogy.

Description: Schooner (circa 1985) reports that "Rudolf Bartsch, in his 'New England Notes', 'Rocks and Minerals' magazine, somewhere around 1940, described a large specimen of lepidolite studded with green crystals of gahnite. It is well to remember, however, that green microlite also occurs there in lepidolite." Considering the lack of confirmed specimens, they are likely microlite.
Reference: Schooner, Richard. (circa 1985), Untitled manuscript on central Connecticut mineralogy.
Galena
Formula: PbS
Habit: cleavable masses
Description: Schooner (1955) says: "often been found at the Strickland Quarry by the author. His specimens are mostly of small size, but they show galena in close association with lepidolite, lithiophilite, spodumene, amblygonite albite, manganotantalite, green tourmaline, and yellow sphalerite". In Schooner (circa 1985) he further elaborates: "At the Strickland quarry, little cleavages of galena have often been collected, intimately associated with feldspar or calcite; also in the whole range of lithium minerals, elbaite, spodumene, montebraesite, petalite, and lepidolite; additionally, in the cesium zeolite, pollucite. The largest mass is about an inch in diameter. Occasionally, there are intergrowths of galena with brown sphalerite. In the pollucite zone, a narrow, irregular seam was filled with galena, yielding the odd combinations already cited."

It is quite possible that natromontebrasite was fairly common... A few masses of Strickland quarry natromontebrasite, from the pollucite zone in the middle eastern wall, halfway down, are composed of intergrown metasomatic or hydrothermal alterations. Pink brazilianite, containing a trace of Mn (analysis by the USGS), is associated with augelite, lacroixite, and hydroxylapatite. This mineral was collected by Charles Thomas, and studied by Mary E.

Petalite
Formula: LiAl(Si4O10)
Habit: granular to cleavable masses
Colour: pale grey to white
Description: Schooner (1958) says: "sparingly associated with the pollucite which the author discovered at the Strickland Quarry in Portland in l954. It was in the form of glassy white or colorless cleavages and coarsely crystalline aggregates." Later, in Schooner (circa 1985), he elaborates: "Good specimens of white petalite, closely associated with colorless pollucite, were collected deep in the Strickland quarry, in the early 1950s. The author appears to have the only such material. It is usually granular, so the perfect cleavage is not as conspicuous as might be expected. The petalite was verified by X-ray diffraction. Similar petalite has been found on the dumps, intergrown with spodumene; the spodumene may be thoroughly altered to 'pinite', whereas the petalite, being much more stable, is in a fresh condition."

Pollucite
Formula: (Cs,Na)2(Al2Si4O12) · 2H2O
Habit: massive, granular
Colour: colorless to pale grey
Description: Schooner (1958) discovered it in l954. "He obtained specimens of glassy material, up to well over a foot across, from a wedge-shaped vein of alkaline minerals which had been exposed by quarrying and subsequently developed by a number of collectors… who threw the pollucite aside, in the belief that it was quartz. The author himself was deceived by this material for a while, even though he had been diligently searching for the mineral in the area. The pollucite, not previously reported from Connecticut, was intimately associated with petalite, spodumene, pink and green tourmaline, amblygonite [montebrasite], cleavelandite, lepidolite, and quartz. Two or three masses had been completely altered to a clay which became waxy on drying, but most of the pollucite was fresh and had a high cesium content."

Description: Usually as small (<1") but well-formed crystals in the mineralized part of the cleavelandite-quartz intermediate zone. Schooner (1958) reports: "W. G. Foye reported [it] in 1929. An analysis of such material, made for Ronald Januzzi, showed the manganese oxide content to be 13.96%. Many rich specimens have been found on the old dumps. The author obtained several superb examples at the vein of lithium minerals in the bottom of the quarry, in 1954. Half inch crystals, and larger masses, were embedded in a matrix of cleavelandite and amblygonite [montebrasite]. The material showed a gradation from dark brown to bright red... the latter nearly transparent and of great beauty. Some was iridescent. The luster was resinous and the manganotantalite exhibited a perfect parting which gave it a micaceous appearance." Some more brown crystals have later proven to be wodginite.

Description: At least one recognizable crystal about 5 cm long was collected by Richard Schooner. Confirmed by Bruce Jarnot, Anthony Albini, and Harold Moritz. Schooner (1958) states that: "There have been reports of topaz...but most evidently refer to the gem quality citrine quartz (the 'topaz' of commerce) which was produced many years ago. Nevertheless, John Tweedy, former operator of the locality, told the author that his company geologist had identified the mineral there in 1953." Later, in Schooner (circa 1985) he says: "Topaz was supposedly verified from the Strickland quarry, at Yale University, a decade ago. It must be quite rare."

Vivianite ?
Formula: Fe2+3(PO4)2 · 8H2O
Habit: thin film
Colour: blue
Description: Reported as thin blue films on weathered lithiophilite. This is unlikely given the absence of Fe in that mineral here. Lithiophilite is commonly associated with blue elbaite here, which could be mistaken for vivianite.
Reference: Schooner, Richard. (1955): 90 Minerals from 1 Connecticut Hill. Rocks & Minerals: 30(7-8): 351-8.
Wardite
Formula: NaAl3(PO4)2(OH)4 · 2H2O
Description: Schooner (circa 1985) reports that "Wardite and wavellite occurred in a fine-grained replacement of natromontebrasite from the Strickland quarry. The rest of the sample was quartz. X-ray study revealed their existence." Natromontebrasite was discredited in 2007 as a mixture of wardite, montebrasite and lacroixite, which were all documented here by the study Schooner mentions.
Reference: Schooner, Richard. (circa 1985), Untitled manuscript on central Connecticut mineralogy.
Wodginite
Formula: Mn2+Sn4+Ta2O8
Habit: tapered, elongated prisms
Colour: dark brown
Description: Fantastic tapered crystals, 2 to 6 cm long, translucent and sometimes showing a little iridescence. Typically in cleavelandite, associated with cassiterite, foitite grading into elbaite, gobbinsite and quartz. Long misidentified as cassiterite or tantalite-(Mn) and too bad as it was not "discovered" until 1963 in Canada and Australia. Strickland could have been the type locality had it been recognized as a new mineral when the quarry was active. Schooner (circa 1985) summarizes its identification: A decade ago, the author found a loose 4 inch mass of montebrasite, studded with sharply formed little dark brown crystals, on one of the Strickland quarry dumps. These were tentatively classified as manganotantalite, despite visual differences. The X-ray pattern was later rechecked, with wodginite in mind, and the fit was close enough to warrant a spectrographic test, which showed the presence of tin. Pete J. Dunn and Peter Cerny have since made probe studies of the material. The original mass was broken into several rich specimens. The wodginite is in equant crystals, transparent under magnification, with a few little tabular amber crystals of manganotantalite. This material obviously represented only part of a concentration of wodginite in montebrasite. Several years ago, Bruce Jarnot encountered a small cleavelandite boulder, on the long narrow dump along the western edge of the hill, yielding maybe a dozen superb thumbnails of sharp, euhedral, reddish-black wodginite crystals, of a pyramidal aspect, up to almost an inch. These, too, were thought to be manganotantalite, until X-ray study proved them to be wodginite. At that point, the author became suspicious of an iridescent brown mineral, embedded in columnar green elbaite, collected around 1950. The X-ray pattern shows it to be wodginite, in yet another habit. Obviously, the mineral has been mistaken for other things!

Wollastonite
Formula: CaSiO3
Habit: granular, bladed
Colour: white
Fluorescence: orange
Description: Found by Schooner in 1953 and 1954, and reported in Schooner (1955): "It is pure white in color, and granular massive in form. Fairly large pieces were obtained from the cores of lenticular quartz-actinolite-grossularite-diopside "horses" [pods] in biotite schist, from near the pegmatite. The mineral is photosensitive, turning brown and ugly if exposed to sunlight for very long. It is faintly fluorescent, in a pale orange tint, and strongly phosphorescent, in a brighter shade of the same color, under short-wave ultra-violet radiations". In Schooner (1958) there is more information: "W. T. Schaller, of the U. S. Geological Survey, made an optical study of this wollastonite, to determine its manganese content through a correlation with the refractive index…which was 1.632, indicating about one percent of iron and manganese oxides." Followed by this passage in Schooner (circa 1985): "Waldemar T. Schaller studied samples submitted by the author. The wollastonite, with tiny embedded tan gehlenite crystals, and occasional light yellow crystals of grossularite, occupies the centers of a few pods, surrounded by concentric zones of fine-grained tan grossularite, white quartz, and greenish diopside. Spurrite, larnite, vesuvianite, and calcite are rarely associated. Spurrite may, indeed, be mixed, granularly, with wollastonite. Small bladed crystals of wollastonite are seen on a few specimens."

Zircon var: Cyrtolite
Formula: Zr[(SiO4),(OH)4]
Habit: short prismatic, parallel groups
Colour: brown or black
Description: Schooner (1955) says that: "crystals are of small size. Parallel groups are often found in cleavelandite and smoky quartz, and other matrices include manganapatite, microcline, lithiophilite, and various mixtures. The crystals have such short prisms that they resemble distorted dodecahedrons, probably being mistaken for opaque garnets by some collectors." The size rarely exceeds 1/4 inch.
