Reference excerpt

The Portland Brownstone Quarries are a set of historic quarries in Portland, Connecticut. The brownstone mined from these quarries was an important source for construction in the latter half of the 19th century. The stone from these quarries was used in a number of landmark buildings in Chicago, Boston, New York City, Philadelphia, Baltimore, Washington, D.C., New Haven, Connecticut, and Hartford. The site was listed as a National Historic Landmark, which also placed it on the National Register of Historic Places, on May 16, 2000.

Early history of the quarry Quarrying on this site began in 1690 by James Stanclift, who contracted with the town of Middletown to build stonework in exchange for a deed of land. Commercial quarrying started in 1783 when the Brainerd Quarry Company began operations. During the peak of the brownstone era, more than 1500 workers were employed by the quarries, which shipped stone on their own ships for eight months out of the year. Proceeds from the quarrying business were deeded to Wesleyan University from 1833 through 1884, and stone from the quarries was used to build many campus buildings. As tastes in buildings shifted, and concrete became the material of choice, the demand for brownstone declined. A flood in 1936 and a hurricane in 1938 flooded the quarries, ending their operations. All efforts to drain the flooded quarries have been unsuccessful; one theory is that the floods opened some underground springs, making it impossible to effectively drain the quarries.

Current use of the quarry site In 1994, a new operator, Connecticut Brownstone Quarries, began a small-scale quarrying operation to provide stone for restoration of brownstone buildings. The town purchased the historic quarries and 42 acres (170,000 m2) of adjacent land in 1999 and 2000.

The quarries have been leased for development as a recreation center and is currently being operated by Brownstone Exploration & Discovery Park, with the hope that awareness of the historic landmark will strengthen the local economy. Over the years the park has gradually expanded its attractions to include scuba diving, climbing and rappelling, swimming, snorkeling, canoeing and kayaking, hiking, mountain biking, wake boarding, cliff jumping, giant inflatable toys, and challenge courses for group team building. All activities are currently available except for the campground - which is currently under construction. There are also plans to offer educational programs at the site. Scuba diving is becoming a popular recreational use within the park, with divers coming from all over Connecticut and even some from out of state. Zip lines Brownstone Park installed two zip lines that cut across the quarry in July 2007. The first line goes from the west side of the park to the peninsula at the center of the park. The second line travels south along the west side of the quarry. The lines are 750 and 780 feet (240 m) long respectively. For the 2010 season, the Park added another two zip lines, one of which is only accessible by climbing up a 65-foot rock wall. Water slide Brownstone Park installed a 100-foot (30 m) water slide in July 2007. Water toys A variety of water toys including kayaks, canoes, launchers, trampolines and windsurfers are available. Wake boarding Several wake boarding lines are available, along with expert jumps and rails. Complimentary beginning lessons are included in the day pass.

Worked examples

Example 1 — a first encounter with Portland Brownstone Quarries

Start with the simplest possible case. Write down what Portland Brownstone Quarries claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Portland Brownstone Quarries before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Portland Brownstone Quarries ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Portland Brownstone Quarries

In research: Portland Brownstone Quarries appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Portland Brownstone Quarries in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Portland Brownstone Quarries is common in secondary-school and first-year university syllabi. It links to neighbouring topics Geography of Middlesex County, Connecticut, National Historic Landmarks in Connecticut, National Register of Historic Places in Middlesex County, Connecticut, so understanding it makes those chapters shorter.
In everyday life: Look for Portland Brownstone Quarries outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
