The City Archaeologist, Joe Bagley, asked us at the Fiske Center if we could conduct a geophysical survey over the area of Langone Park that, 100 years ago, had a tank which ruptured and caused The Great Molasses Flood of 1919.  This is in preparation for Tuesday January 15th, the 100th anniversary of the disaster.

For our archaeological geophysical survey we used two common techniques: ground penetrating radar (GPR) and electromagnetic (EM) conductivity.   The results will be presented in the next post.

Before we interpret the results of a geophysical survey, we try and georeference every map we can of the area in question.  The georeferenced maps allows us to better understand the geophysical results.  Thus, below is a sample of some of the many maps that we looked at, to understand the complex history of this park.  Today, the park has a little league / softball diamond, and the outline of that feature is shown in brown on each of the georeferenced maps (which are mostly from the Norman B. Leventhal Map & Education Center at the Boston Public Library).  In  great article in the Boston Globe Magazine, you can see a georeferenced 1917 map showing that the location of the tank is in the general area of the diamond.   However, the Wikipedia map shows a smaller tank more north and a building between the tank and Commercial street.  Joe Bagley wanted us to see if we could refine the location of the tank that ruptured in 1919. Over time, maps generally become more accurate, but just how accurate, and how well out team has georeferenced them is and issue that we study intently.  Geophysical results can sometimes help us better georeference the maps and understand what parts are accurate, and what parts might require a little change.   This is akin to the work we have been doing in Plymouth, combining geophysics and georeferenced maps,  getting ready for the 400th anniversary of that colony.

1775 Map depicting the shipyard that occupied the area where the tank collapse

The landscape of Boston has been altered heavily over the past four hundred years.  The evolution of Boston’s landscape is evident in historic maps that depict the city’s waterfront property.  Maps, such as the ones shown in this sequence, are extraordinarily important sources of data about the past. These maps detail the dynamic history of the North End in Boston.

The Great Molasses Flood of 1919, took place in a relatively small portion of the North End’s extensive history and has hardly left a mark on the landscape. The flood occurred on January 15th, 1919, when a 50 ft. tall and 90 ft. in diameter molasses storage tank, owned by the Purity Distilling Company, collapsed.  The collapsed tank then tipped over creating a wave of molasses close to 25 ft. tall which killed 21 people and injured up to 150. Today this is what the area looks like.

1814 Map.  surveyed by J.G. Hales ; J.R. & Penniman.

Starting with the 1722 Captain John Bonner map of the, then, town of Boston, which shows the then active docks that occupied much of the Boston shoreline.  This map was a monumental beginning to modern cartographic detailing that documented Boston’s shoreline. The docks, that are clear in the 1722 map, suggesting  dry and wet docks in the 18th century.  In a redrawn 1775 map, the area where the tank was located in the 20th century, was occupied by Hunts and Whites Ship yard.  In this georeference, the park diamond is centered on the “ar” of Ship Yard.

In an 1814 map, Commercial Street was labeled Lynn Street and the softball diamond seems to be on the mostly dry land with a building to the east.  According to an

1852 Map surveyed and drawn by J. Slatter & B. Callan.

1852 map the adjacent street is now Commercial Street and a substantial amount of land has been added in the form of docks.   It is not clear if the building along the first base line is the same one depicted in the 1814 map, but certainly the building curving around 3rd base seems to be new. The two border lines

coming together at the pitching mound may be visible in some of the geophysics, and will be seen in many of the later maps.

The same basic configuration is also visible in the 1861 map, made by the City.

Cartographer: Daniel Alfred Sanborn

An 1867 map is the first real detailed map of the area. It is also one of the early famous Sanborn fire insurance maps.  It shows several coal sheds and hints that the building along the first base line, first seen in the 1814 map, might still be there 50 years later.

George Washington Bromley 1890 map

The  1890 Bromley map suggests that the “V” of two docks,  meeting at the pitchers mound, first seen in the 1852 map, is still present but that the building  that used to be along the first base line, is now substantially larger.  The docks are also very different.  A image of these kinds of docks can be seen in the birds eye view of downtown Boston dated 1877.  These docks were an active hot spot for landscape change during

Bachman 1877 birds eye view

the 18th and 19th centuries.  Further construction of larger docks and land masses were very common during these centuries by building cribbing or sinking ships to artificially fill in the harbor

By the 1908 map, the lot will take on the

basic shape, the distilling company is labeled as the owner, and a small tank is indicated in the middle of the lot.

1912 George Washington Bromley map

This may be where the Wikipedia map gets its layout.  In this initial 1908 map one large building can be seen in pink that is replaced by multiple buildings in the following 1912 map.  The 1912 map shows a similar small tank but smaller building on Commercial St, and tracks going into the adjacent lot. To the right of the new park area is the soon to be location of the Purity Distilling Company which seems to have built larger molasses tanks as the business grew. This map shows the first distillery’s tank with two new buildings along side a new above ground railway.

1917 Bromley Map probably showing the tank before destruction.

A 1917 map shows the distillery buildings and the large molasses tank before the accident.   The 1917 map is what we will base much of our interpretation on.  It almost surely shows the large molasses tank that burst during the 1919 disaster as well as two new buildings.  This is the final map that the distillery appears on.  A 1922 map shows the absence of a distillery and tank, replaced with reused buildings by railway operations. Our final map, from 1938, again shows all of the buildings in the 1917 map, with the addition of a small shed where the pitcher’s mound is today.  In 1973 Langone park  was created.

Updating Cape Cod 3-D Model

Our work with the Cape Cod National Sea Shore  continues as we monitor erosion trajectories.  This 3-D model was built to aid in quantifying beach erosion over time. While the data is collected for purely scientific reasons, I made a fly through movie using photos and GPS control points taken by John Schoenfelder, John Steinberg, Melissa Ritchey, and Jocelyn Lee.

Summer Field Work on the Cape Cod National Seashore

 

This past summer has been a busy and productive one for the members of the Fiske Center. In conjunction with the National Park Service (NPS), Cape Cod National Seashore one of the more interesting projects was to assess and to aid in management of a series of potentially endangered archaeological sites in Wellfleet, MA.  The project area is on Great Island and Great Beach Hill, which are the two largest sandy areas that make up the peninsula that defines the western side of Wellfleet harbor and separates it from Cape Cod Bay. This is a dynamic area and one of the island towns in the area has already been submerged. These islands have been found to have both Native American and European Colonial archaeological sites. The most famous site in the area is the Samuel Smith Tavern. This site was excavated by James Deetz in 1969 and 1970.  More recently, in 2012, the area around the Samuel Smith Tavern was explored by The Public Archaeology Laboratory in cooperation with the NPS. Reassessing the extent and preservation of the Tavern site was a central part of the current joint project. As part of that work we georeferenced the 1969 and 1970 excavation datum and the earlier excavations boundaries were redefined, in light of later, much more extensive work.

During the PAL survey, there were several large shell middens identified that were eroding out of sea bluffs on Great Island and Great Beach Hill. Shell middens are trash piles, and as the name suggests, consist of mostly shell. Several of the eroding shell middens are on sandy cliffs that are 80 feet high and at the same time deeply buried by wind-blown sand. These conditions make the sites difficult to assess, let alone excavate. One of the outcomes of the joint NPS-Fiske Center project will be to assess the shell middens likelihood of suffering further erosion as well as to define their areas.

Thus, for three weeks in August the crew set out on the two and a half mile hike every morning to develop answers to these questions. Stay tuned for what we found.
