A pegmatite quarry operated on the so-called "Eastern Dike" of the White Rock District. It was operated by the Consolidated Feldspar Company from before 1910 to at least 1927, but was inactive during the early 1940s. Quarrying was resumed in 1959 and greatly expanded along the Eastern Dike by The Feldspar Corporation and continued until the 1970s. At this point the main quarry was filled in and now is covered by the Kleen Energy power plant, but a small satellite quarry to the immediate south and exhibiting similar mineralogy was not filled, though it is enclosed within the power plant property an no longer accessible.

Schooner (1958) called this the "upper" White Rocks quarry and due to its complex mineralogy, it is the "White Rocks" quarry cited in most references, even if not specifically differentiated from other nearby quarries.

Bastin (1910) wrote the first description of ores, quarrying, and processing operations:

At the time of the writer's visit, in November, 1908, the quarry consisted of a single open pit on a north hillside and had not been extensively worked. The rock is typical granite-pegmatite and contains no masses of pure quartz that are large enough to be of commercial value. The feldspar is cream-colored microcline, in most places finely intergrown with small amounts of albite. Muscovite occurs in crystals 3 to 5 inches across and from 2 to 3 inches thick, but is rendered worthless by the presence of ruling and wedge structure. The principal iron-bearing mineral is biotite [annite], which occurs in lath-shaped crystals 1 to 2 inches wide, and is very abundant in some parts of the pegmatite. Black tourmaline is rare. The ledge that is now being worked and a number of others on this property contain considerable amounts of feldspar of pottery grade.

The material is taken by tramway downhill for about half a mile to the mill, which is at the side of the railroad and also within a few rods of Connecticut River, so that shipments may be made by water if desired. The mill is equipped with a gyratory crusher, crushing rolls, rotary drier, and two tube mills, 18 by 6 feet, whose capacity is stated to be 30 tons in ten hours. It is the purpose of this company to use the better grade of material for pottery purposes and to crush the remainder for use as poultry grit and in the manufacture of ready roofing. Power is furnished by a gas engine and gas producer.


A few years later, A. S. Watts (1916) examined the chemistry and suitability of the ores for porcelain production. The Consolidated quarry was so described:

The dike has been opened along a northeast face, showing a width of about 50 feet. The composition of the dike is decidedly variable. In many places it is remarkably free from impurity and shows considerable masses of pure buff feldspar of the potash variety; in others it is very fine-grained pegmatite with much mica and small garnets. The gradation is so pronounced, however, that no difficulty in sorting would be experienced.

The east dike is a widely varying mixture of potash feldspar pegmatite and soda feldspar pegmatite. It is much smaller in extent than the west dike and shows a structure similar to the gem bearing dikes of Maine. Much cleavelandite is scattered through this dike, and black, pink, and green tourmaline are noted, although the tourmalines are all opaque and not of the gem quality.


Because the quarry was not active during World War II, the description done by Cameron et al (1954) was very limited and no map was made:

The pegmatites consist essentially of quartz, plagioclase, perthite, and muscovite, with accessory garnet, tourmaline, beryl and other minerals. Biotite [annite] is abundant in one of the quarries. Beryl occurs most commonly in pods, associated with coarse quartz, perthite, and muscovite. Tourmaline is present in some pods. The beryl crystals are as much as 12 inches long and 6 inches in diameter. The pods are small and widely scattered, so that the average beryl content of each pegmatite is low. In a quarry about 200 feet long, on the north slope of White Rocks just below the summit, beryl occurs also as crystals ΒΌ to 1 inch in diameter and as much as 1 inch long, sparsely scattered in a medium-grained matrix of quartz, plagioclase, muscovite, and accessory garnet and tourmaline. The average percentage of beryl in this material is very low.

None of the quarries revealed mineable amounts of book muscovite, which occurs only in the pod deposits.


When open to collecting, collectors frequented the quarry before it was filled, and the similar, small satellite quarry at its southern end after the main one was filled. Because it has lithium and rare-element-rich chemisty, this quarry (along with the smaller but similar Riverside Quarry on the same dike) produced the most species, and most of the preserved specimens, from the district.
