Redstone Quarry

Natural Area: Redstone Quarry

About Redstone Quarry

Body

Nestled in a quiet neighborhood within the city of Burlington is the 3-acre Redstone Quarry Natural Area. The quarry is named after the Monkton Quartzite, or “redstone” that was quarried there for over 100 years and used as building material for many of the older buildings in Burlington. A small pond, wetland, and wooded areas provide ecological diversity on the site. Neighboring residents have helped to maintain and steward the Natural Area and UVM thanks them for keeping the trails open and the area clean. 

Research

Body

Research at the quarry is primarily focused on geological studies, illustrating regional history through exposed rock layers and ancient ripple marks. Scholars from various regional academic institutions observe these unique formations and investigate how rocks are formed through deposition. Ongoing research includes the establishment of study sites to monitor population trends for birds, amphibians, reptiles, and aquatic macroinvertebrates within the small wetland.  

Education

Body

Redstone Quarry serves as an outdoor classroom for the University of Vermont, Middlebury College, and local public schools. The site provides hands-on field trip opportunities to observe Monkton Quartzite and ancient shoreline features. University of Vermont faculty and students study the complex interplay between geological history and local ecology. Students also engage in active stewardship through courses like "Applied Natural Areas Conservation and Stewardship," where they develop real-world management plans for vegetation and trail systems. 

Community

Body

The quarry is deeply integrated into its suburban neighborhood, with local residents serving as key partners in the daily maintenance and monitoring of the 3-acre site. Community members enjoy the area for quiet recreation, including bird watching, picnicking, and winter skating on the pond. The University maintains active outreach to neighbors to address stewardship concerns such as yard waste disposal and graffiti removal. This collaborative relationship ensures the natural area remains a respected and well-cared-for resource within the City of Burlington. 

Property Description

Body

Since the quarrying operation was closed in the 1920s, the site has gradually revegetated with both native and non-native trees, shrubs, and herbaceous plants.  Geologic features that were once readily observed are now more challenging to access due to vegetation cover. The primary ecological feature of the site is a pond and wetland at the base of the cliff face. The pond, once used for ice skating, has gotten smaller over the years. Frogs, turtles, and a variety of birds and mammals provide impressive ecological diversity for this small, urban site. Invasive plants such as buckthorn and honeysuckle have taken hold around the wetland and provide a management challenge for students of restoration ecology. UVM and local residents maintain a trail network throughout the site.  Three parking spaces are provided for visitors. 

History

Body

Levi Willard started cutting rock from the quarry in 1805.  It was then known as “Willard’s Quarry”. The redstone he extracted was a popular building material in the 1800s.  Redstone campus, formerly the Buell estate, has many buildings constructed of the reddish brown stone.  The County Courthouse and College Street Church in downtown Burlington are constructed of it as well.  By the 1900s, concrete had replaced quartzite as a building material and the quarry closed due to lack of demand in approximately 1920. UVM purchased the land in 1958 to be used primarily for geology classes.  In 1974, when the Board of Trustees designated the UVM Natural Areas, Redstone Quarry was included.
