The Great Mill Disaster (also known as the Washburn A Mill explosion) occurred in Minneapolis, Minnesota, United States in 1878. The disaster resulted in 18 deaths. The explosion occurred on the evening of Thursday, May 2, 1878, when an accumulation of flour dust inside the Washburn A Mill (the largest mill in the world at the time) led to a dust explosion that killed the fourteen workers inside the mill. The resulting fire destroyed several nearby mills and killed a further four millworkers. The destruction seriously impacted the city's productive capacity for flour, which was a major industry in the city at the time. Following the blast, Cadwallader C. Washburn (the mill's owner) had a new mill, designed by William de la Barre, constructed on the site of the old one. This building was also later destroyed, and today the building's ruins are a National Historic Landmark and operated as part of the Mill City Museum.

Mill Ruins Park
Mill Ruins Park

Mill Ruins Park is a park in downtown Minneapolis, Minnesota, United States, standing on the west side of Saint Anthony Falls on the Mississippi River and running from 3rd Ave. S. to about 9th Ave. S. The park interprets the history of flour milling in Minneapolis and shows the ruins of several flour mills that were abandoned. The park is the result of an archaeological study of the Saint Anthony Falls Historic District. The district was listed on the National Register of Historic Places in 1971. In 1983, a project was being considered to extend West River Parkway along the west side of the Mississippi River in downtown Minneapolis. Scott Anfinson, then the municipal county highway archaeologist for the Minnesota Historical Society, developed a plan to assess archaeological sites along the riverfront. A number of test excavations along the route revealed a wide variety of sites containing items of interest. In the Bassett's Creek area, for example, the foundations of two sawmills and the remains of a railroad roundhouse were found, while near Hennepin Avenue, the investigation found the footings of the Great Northern Railway Union Depot and the tower bases of the first and second Hennepin Avenue Bridges. In the milling district, archaeologists found clues suggesting that there were still extensive remains of the foundations of the mills and waterpower system.The first round of archaeological surveys in the 1980s was intended to save the ruins from destruction as a result of road construction projects. Later, in the 1990s, the focus shifted from environmental impact assessment to exposing ruins for their interpretive value. As the ruins were made visible to the public, the goal was to create assets for education, tourism, and commercial development. The excavations for Mill Ruins Park began in 1998 and continued through 2001. The process also involved stabilizing the remains of the Washburn "A" Mill, which had burned in 1991. The Washburn "A" Mill became part of the Mill City Museum.Along with the remains of about 20 flour mills and other industrial buildings, the park also contains two stone piers and several iron girder piers that held a trestle for the Minneapolis Eastern Railroad. The tailraces from the waterpower canal are also clearly visible, and the water flow has been restored through the canal. Signs posted along the walkways interpret the ruins and the history of the area.

J.I. Case Building
J.I. Case Building

The J.I. Case Building in downtown Minneapolis, Minnesota was a warehouse and branch headquarters of the J.I. Case Threshing Machine Company. The building was part of a new warehousing development in Minneapolis, because wholesalers were starting to outgrow the warehouse district on the north side of downtown. Former Minneapolis mayor William Henry Eustis was promoting a new warehouse district on the south side of downtown, and had attracted some farm implement companies by the early 1900s. The J.I. Case Building was listed on the National Register of Historic Places in 2021 for its role in commerce and in community planning and development. Jerome Increase Case founded the J.I. Case Threshing Machine Company in Racine, Wisconsin in 1842. The company acquired a reputation for good customer service and high-quality products. Their products were sold by independent jobbers, as well as a network of company-owned distribution houses known as "branch houses". The J.I. Case Implement Company, a jobber, initially started sales at a warehouse at 308-310 Third Avenue North, in the traditional warehouse district. By 1900, they had expanded their warehouse space, but they needed more space than was available in that district. Minneapolis was becoming a major hub for the distribution of farm machinery, and by 1908 it was the largest distribution point in the world. By 1915, the dollar volume of farm implements sold in Minneapolis exceeded the dollar volume of the flour and grain trade. William Henry Eustis was promoting a new warehouse district on the south side of downtown, but there were some seedy elements in that part of town. An alley south of Washington Avenue between Park and Chicago Avenues was known as "Fish Alley", because a fish market had previously been located there. It was surrounded by overcrowded apartment buildings and was known for drinking parties and fights. Residents were warned, "It isn’t safe to go into the alley, unless you have a gun and policeman with you, and then you are not safe." There was also a dance hall and four saloons facing Washington Avenue on the block. By 1906, only one saloon remained, as a result of an effort to clean up the area, and fighting was reduced, but Fish Alley was still known for criminals and loose women. Some redevelopment was occurring in the area, though. The Great Northern Implement Company (also known as the Pittsburgh Plate Glass Company Building) built a location west of Park Avenue on Third Street. Advance Thresher built an architecturally distinguished structure on the east side of Park Avenue at Third Street, and Emerson-Newton Implement Company built a building immediately adjacent to Advance-Thresher. In the spring of 1903, Case purchased several properties on Washington Avenue between Park and Chicago Avenues. By September 1903, Case applied for a building permit for a "large $125,000 building". Construction did not begin immediately, though, because the company was preoccupied with a warehouse fire that destroyed 110 threshing machines, a new headquarters building in Racine, and a new thresher made entirely of steel. By September 1906, the company was finally ready to build, so they applied for a building permit for a brick warehouse with three stories and a basement, 70 feet (21 m) tall and measuring 115 feet (35 m) by 132 feet (40 m) with an estimated cost of $50,000. They selected the firm of Kees and Colburn, who had designed the Advance-Thresher and Emerson-Newton buildings on the same block. The building was completed by October 1907. By the late 1950s, farming was facing a change. 850,000 farms had been lost between 1954 and 1959, and other farmers bought out the land of those farms that folded. With fewer farmers and larger farms, the sales of agricultural implements had dropped 25 percent by 1960. Downtown Minneapolis was also changing, with more traffic and older buildings that had accumulated deferred maintenance during the Great Depression and World War II. In 1959, Case moved its branch office to a building on Minnesota State Highway 55 in Eagan, Minnesota. The downtown Minneapolis building became a warehouse for Minneapolis House Furnishings. In the early 1990s, the building was remodeled to house offices and a restaurant, the Old Spaghetti Factory, which opened in 1994. The Old Spaghetti Factory closed in 2019.

Saint Anthony Falls
Saint Anthony Falls

Saint Anthony Falls, or the Falls of Saint Anthony (Dakota: Owámniyomni, lit. 'Three Whirlpools') located at the northeastern edge of downtown Minneapolis, Minnesota, is the only natural major waterfall on the Mississippi River. Throughout the mid-to-late 1800’s, various dams were built atop the east and west faces of the falls to support the milling industry that spurred the growth of the city of Minneapolis. In 1880, the central face of the falls was reinforced with a sloping timber apron to stop the upstream erosion of the falls. In the 1950s, the apron was rebuilt with concrete, which makes up the most visible portion of the falls today. A series of locks were constructed in the 1950s and 1960s to extend navigation to points upstream.The falls were renamed from their Dakota title in 1680 by Father Louis Hennepin after his patron saint, St. Anthony of Padua. The towns of St. Anthony and Minneapolis, which had developed on the east and west sides of the falls, respectively, merged in 1872 to fully use the power of the falls for milling operations. From 1880 to about 1930, Minneapolis was known as the "Flour Milling Capital of the World". Today, the falls are defined by the spillway, the upper dam and the locks, located just downstream of the 3rd Avenue Bridge, and the Lower Lock and Dam, just upstream of the I-35W Saint Anthony Falls Bridge. These locks were built as part of the Upper Mississippi River 9-Foot Navigation Project. The area around the falls is designated the St. Anthony Falls Historic District and features a 1.8-mile (2.9 km) self-guided walking trail with signs explaining the area's past.

Saint Anthony Falls Laboratory
Saint Anthony Falls Laboratory

The Saint Anthony Falls Laboratory (former name: Saint Anthony Falls Hydraulic Laboratory), or SAFL, is a research laboratory situated on Hennepin Island in the Mississippi River in Minneapolis, Minnesota, United States. Its primary research is in "Engineering, Environmental, Biological, and Geophysical Fluid Mechanics". It is affiliated with the University of Minnesota's College of Science and Engineering. Research is conducted by graduate students and faculty alike using the 16,000 square feet of research space and 24 different specialized facilities. The laboratory is unique in that its location next to Saint Anthony Falls allows it to use the hydraulic head from the waterfall to provide water for many of the experiments. The experiments performed at the laboratory are varied, and may include: Contract civil and environmental engineering work, such as dam construction and removal Understanding river system dynamics Work with oil exploration to characterize deposits in deltaic systems Work to understand the interactions between fluid flow and the ecology of rivers Work to understand cavitation in fluids in order to build better propellersThe Saint Anthony Falls Laboratory is also the headquarters of the National Center for Earth-surface Dynamics, a National Science Foundation Science and Technology Center.The laboratory is a contributing resource of the Saint Anthony Falls Historic District which is listed on the National Register of Historic Places.
