Transforming a Coal Mining Site with Nature: "Mary's Garden" Reclamation
"Mary's Garden" occupies a site that was continuously mined by the Delaware and Hudson Coal Company for almost 90 years. The land was subsequently mined by the Glen Alden and Raymond Collieries prior to being purchased in 1969 by the Sisters, Servants of the Immaculate Heart of Mary.
"Mary's Garden" consists of sculptural configurations that form images of flowers associated with the Blessed Virgin" the "Madonna Lily" and the "Rose." The project is loosely structured around the joys and sorrows within the Immaculate Heart of Mary the Mother, and then extrapolated to the sufferings and steadfastness of the coal miners and their families.
I just spoke about this project at the National Association of Abandoned Mine Land Programs. As you might expect, the audience was mostly mining engineers, subsidence and acid mine drainage experts and land remediation professionals. When I finished speaking there was stunned silence" then many questions. I don't think many of these engineers had considered the idea of multiple functions, art, trails, wildlife and connections to the local community. Most of the projects I saw had compacted the land and put in a Wal-Mart.
Our site" the Marvine Colliery (Hudson Coal Company) was purchased by Glen Alden Corporation in 1961, and then the Raymond Colliery bought the land in 1964. It wasn't until 1969 that the Sisters acquired this tract (they kept adding to their holdings)" but, in places where there is mining, all you acquire is the surface of the property. Others continued to own the mining rights, and this set up all sorts of conflicts between the Sisters, Servants of the Immaculate Heart of Mary and the mining companies, who continued to mine under their buildings.
The "Madonna Lily" occurs at the edge of a site that has recently been restored by the Pennsylvania Bureau of Abandoned Mine Reclamation using typical engineering methods. Volunteer trees and vegetation have been removed, the land has been compacted into stabile terraces" now used as platforms for athletic fields, oversized rip-rap channels conduct water off the land, and all traces of mining history have been erased, in stark contrast to the five-acre wooded ravine that still exists.
Lying beneath these massive man-made terraces, the "Madonna Lily" captures and stores stormwater from the upper campus, and provides access to a constructed wetland filled with plants that purify stormwater. The five-foot wide paths over water create microhabitats for wildlife, and offer students opportunities for field study in phytoremediation, bioremediation, ecology and aquaculture.
A similar project, "Fair Park Lagoon" in Dallas" a municipal flood basin built more than 25 years ago" continues to attract people and wildlife, and also serves as an educational resource while purifying water.
The image of the lily is created from a composite of elements relating to the formation of coal, acid mine drainage, the Immaculate Heart of Mary, and the history of the Sisters who founded Marywood University.
We know that coal originated in ancient swamps, and that contemporary swamp plants and limestone purify water. A filter feeder found in ancient swamps" a crinoid" serves as the center of the Madonna Lily, with its long waving arms providing paths through the wetland. The crinoid's "star-shaped" columnal can be interpreted as the Star of
Bethlehem" one of the joys within the Immaculate Heart of Mary" while from a water quality perspective, the gold can be seen as pyrite (iron disulfide)" one of the causes of acid mine drainage. The white color of the lily is both a symbol of purity, as well as the actuality, since calcium carbonate and limestone neutralize acid and purify water.
As it proceeds toward the forest, the green stem of the lily becomes black and shiny, simulating the anthracite coal outcroppings found throughout the site.
The Marywood ravine offers an alternative to the engineered version of land reclamation. Here tall trees grow out of the tops of dump piles and the landscape is dotted with rusted pipes that served as ventilation for the seven levels of subterranean mines below.
Surface water does not flow on this site. Instead it drops down through caverns and voids into the "Mine Pool"" a huge underground lake that underlies the city of Scranton and much of Northeastern Pennsylvania. One goal of this project is to use this warmer underground water as a geothermal resource to help meet the university's energy needs.
Just recently, they've started doing the test boring for geothermal energy by using the mine pool. In addition to healing the land, Marywood will have access to free energy. Thus, the mine pool could ultimately have benefits.
Another goal is to restore surface water as a life-giving source for plants, wildlife and the Lackawanna River.
"Mary's Rose" unfurls as a series of concentric circles, following the natural topography of a tree-sheltered ravine down to the bottom. Formerly, a small creek flowed here" a tributary of the Lackawanna River" prior to the disruption of the watershed by intensive mining activity. Today the path of the creek can still be seen, and the creek bed is often damp following rainstorms, as water disappears into the mine pool below.
At the center of the "Rose," a lined, heart-shaped pool invokes water-filled "strip pits," where generations of mining families skated and swam" as well as the "Immaculate Heart of Mary." The pond offers life-giving water to wildlife, as well as reflections of the surrounding forest. A small spillway oxygenates the water as it enters the pool, which is connected to the restored creek. The inner circle of "rose petals" serves as sculptural seating for students and visitors within this meditative and deeply historical place" formerly part of the Marvine Anthracite Colliery.
Moving up the slope, the middle circle of "rose petals" reveals the coal-mining geology of the Lackawanna Valley's Llewellyn Formation, with its layers of red shale, sandstone, conglomerate, limestone and anthracite coal. Typical synclinal formations, recumbent folds and overturned strata are both decorative and instructive, revealing the geological history of this place, while landscaping consists of plant pockets that nest within the fissures of the rock.
The outermost circle of "petals," the "Crown of Thorns," is planted with brambles" roses and blackberries" and other local plants that were significant to mining families. They also provide food and thickets for wildlife, and help buffer the sound of traffic along Olyphant Avenue.
Hematite nodules within the "Rose"" iron concretions that are found throughout the geological formation as well as in the ravine" rust and drip like blood, recalling sorrows within the Immaculate Heart of Mary. And the topography of the ravine, itself, creates the sense of looking down into the center of the flower.
"Mary's Garden" reveals a landscape where the healing power of nature stands beside the monolithic goals of typical land reclamation. Within the ravine there is no longer any hint of the wasteland of culm banks, slag heaps, poisonous waste ponds, or the many fires and deaths that occurred on this site" or the fact that seven layers of subterranean passages and chambers lie beneath our feet.
Paths through the ravine curl around and draw attention to remnants of the mining era, while honoring the work of nature that is reclaiming its own territory.
By evoking the mining history at this site, the joys and sorrows of intertwined lives, and overlapping patterns from carboniferous swamp to the present day, "Mary's Garden" underscores the fact that within an ecological community every element is essential to functional well being, and redemption is always at hand.
????????????????????????????????????????????????????????????????????????????????????????????????????????????
Here are some of the plants being used for stormwater purification in the "Mary's Garden" reclamation. This is not all of them, but they are the ones listed on the drawing ???Madonna Lily'. Following the oxygenation and intake/sediment pond, there is:
Dense Filtering Vegetation:
Sedges and Rushes:
This one REMOVES HEAVY METALS:
Snails and microbes consume pathogenic bacteria such as fecal coliform, and the root excretions of many of these plants remove disease bacteria from water. Among the most effective plants in this category:
These plants have large roots, which increases the number of microbes that consume ammonia and break down chemicals and pesticides into simple compounds that can be absorbed by the plants:
Thickets of plants that root in shallow water provide habitat for phytoplankton, which remove nutrients from water:
Bird And Butterfly Garden:
