In 1893, James J. Hill's Northern Steamship Company built 385-foot ocean style passenger steamers. In 1911, the peak year, 80,000 passengers traveled to Lake Superior. After 1920, the number of passenger cruise ships diminished with the advent of "motor-cars." Very few cruise ships were still in service after World War II. The Canadian steel steamer Huronic was constructed in Collingwood, Ontario, in 1902. She ran on the Northern Navigation Division of the Canadian Steamship Company, on cruise trips from Detroit to Duluth. In 1940, the Huronic was dismantled and made into a package freighter.

Ore boat leaving Duluth. Detroit Publishing Co. was a prolific post card publisher, especially in the U.S. Their cards were published from 1898 to 1933. Using a color process called Phostint, their cards were considered to be very artistic. The hobby of collecting post cards is called deltiology. The first post card was issued by the Austrian government, America's first postcards came out in 1873. Picture postcards were introduced later. The golden age of postcards was supposed to date from 1907 through the first World War.

Hillside housing stock built with a rock outcrop in the backyard; A Master Bread billboard is at the top of the image. The Zinsmaster family opened a bakery called Zinsmaster Hol-Ry Company in Duluth in 1931. Master Bread was one of their brands. The structure that looks like it is framed by the Aerial Lift Bridge is the Huron Portland Cement silo that later became LaFarge Cement. It still stands on the Duluth waterfront. The white trimmed brick structure at the top right is 1515 West Superior Street, the Duluth Gospel Tabernacle building. The building to the right but further east on Superior Street with the arched window is a Minnesota Power station and garage at about Fourteenth Avenue West and Superior Street.

This photograph may have been shot from Seventh Street and about Lake Avenue. The bright narrow strip in the lower middle of the image is Lake Avenue leading to the Aerial Bridge. The rectangle and three dots parallel to the piers of the canal are the remnants of the Whitney rock crushing enterprise. The Whitney Brothers, of Superior, Wisconsin, had a sand and gravel processing business that was functioning in 1919. The concrete form that is still in the water was the dredging/crushing building. A tunnel ran from the building to the Point. There was a conveyor belt and railroad spur adjacent to the concrete building. Sand from the Apostle Islands and gravel from Grand Marais were carried to Duluth on a small vessel named Limit. The business also used a tug the William A. Whitney. The Limit was secured to the concrete building and the load of sand or gravel was unloaded into the steel hopper using a jaw-like clam shell, steam powered device. The belt conveyed the materials to shore and it dropped into a tunnel where trucks were ready. On Federal lake charts it is referred to as cribs. Telephone lines are in this photograph. In 1880, the first telephones were installed in Duluth by Walter Van Brunt for C. H. Graves and Company. In 1881, the Duluth Telephone Company was incorporated with $10,000 capital. In 1882, the first telephone directory was issued for 30 subscribers. In 1898, long distance lines between Duluth, Cloquet and Carlton were strung. In 1899, Duluth had 794 telephones. In 1900, the Zenith telephone Company (independent) started operations in competition with Duluth Telephone Company. The tower is the Central High School clock tower. The 1892 school has been the Central Administration Building for ISD 709 since the late 1970s.

Whaleback is an unusual ship design with steel hulls (body of the vessel) and rounded decks (boat, hurricane, main -which is the lowest full-length deck in a ship's hull, and spar are all decks at different levels) which was introduced by the inventor Captain Alexander McDougall of Duluth in 1888. It was a very stable vessel. American Steel Barge Company, a New York corporation engaged in shipbuilding and transportation on the Great Lakes as well as on the Atlantic and Pacific coasts, purchased all of the patents for McDougalls whaleback vessels for $25,000. The only remaining whaleback is the Meteor, which is now a museum at Barker's Island in Superior, Wisconsin.

The Chicago Shipbuilding Company of Chicago, a subsidiary of the American Shipbuilding Company, built the steamer William E. Cory for the Pittsburgh Steamship Company in 1904. The vessel dimensions are 569' X 56' X 31'. She sailed from Chicago on her maiden voyage August 12, 1905 bound for Duluth to load iron ore. The aerial bridge was new. Bids were opened March 25, 1901, but only one was received. The Duluth Canal Bridge Company was awarded the contract but abandoned the work. In February 1904, the Modern Steel Structural Company of Waukesha, Wisconsin was issued a contract. Work began July 20, 1904. On February 23, 1905, with local dignitaries at hand, the bridge was first operated. Regular service began the next day according to newspaper accounts. The city engineer's report for 1905 stated that the bridge was "completed and commenced operation on May 5, 1905, and a few problems were corrected in running the bridge over the next few days." The Aerial bridge was completed in February 1905. The aerial bridge transporter or gondola or transfer car roadway was 17 feet by 50 feet with sidewalks seven feet by 50 feet, the cabins were 30 feet long. The U.S. Army Corps of Engineers office building with flag above it was built in 1906. Also visible in the image are the National Biscuit Company 517 Lake Avenue South, Blanchet Hotel 520 Lake Avenue South, and Wieland Flats 502-512 St. Croix Avenue

139-D The caption of this post card says The unique Aerial Lift Bridge and Ship Canal Entrance to Duluth-Superior Harbor is an outstanding attraction of this popular summer vacation city. Total bridge load lifted is 900 tons. Only 55 seconds are required to lift the span 135 feet. The Harbor is second only to that of New York City in shipping tonnage and through it passes about 60 per cent of America's iron ore production, from the great iron ore ranges just north of Duluth. Another fact, not included in the caption is that John H. Darling (1847-1942), U.S. Engineer for Duluth-Superior Harbor, oversaw replacement of the original wooden canal piers with concrete piers in 1897. The piers have been maintained and repaired with a major remodeling/rehabilitation in 1985-1986.

An ore boat is steaming through the canal into Duluth harbor. The canal was cut beginning in 1871, and this bridge was built in 1904-1905 and modified with the lift span (which is up in this photo) in 1929. Canal Park is to the right of the Aerial Lift Bridge. Today a tourist destination, Canal Park was originally an industrial site. In this photograph Canal Park is in transition. You can see some demolition as well as some new parking facilities very near the pier including green space for residents and tourists to get near the vessel traffic and the bridge. The Aerial Lift Bridge is the largest tourist draw in Minnesota.

The parallel concrete piers jut out into the lake forming the canal leading to the harbor. Since its remodeling into a lift bridge in 1930, every vessel passes under the Aerial Lift Bridge's raised span. In this view the span is down, and traffic and people cross it as a roadbed. The South Pier is at the left, the North Pier is at the right. Minnesota Point's light sand beach draws residents and tourists in all seasons but especially throughout the summer months. The expanse of the slips and wharves of the harbor indicate an industrial scene. You can see the light road that is Skyline Parkway parallel to the horizon running the length of Duluth.

The Duluth Missabe and Iron Range ore docks are the two reddish brown linear structures in the foreground. Ore boats are pulled between the docks by tugboats. Railroad cars loaded with ore or taconite pellets move along the railroad tracks on the top or the length of the dock. A chute or steel pocket beneath the tracks is lowered to the open cargo hatch and a door at the bottom of the pocket opens, allowing the pellets to run into the ore boat that moored parallel to the dock. Four hours is typical for loading ore. Loading is the responsibility of the First Mate. It is important to load the ore in a proper sequence to avoid over stressing the boat unevenly. Each chute (or drop of pellets) is about 20 tons.

Looking toward the North Shore this aerial view shows the Duluth Arena Auditorium on the lower left. The Arena Auditorium opened in August 1966 and was renamed the DECC or Duluth Entertainment and Convention Center in 1987. Just below the Arena Auditorium is the building that housed the Flame Restaurant. Located at 353 South Fifth Avenue West, the Flame opened in 1930 and closed on January 3, 1973. The water of Minnesota Slip is visible between Canal Park and the Arena-Auditorium. Off the shore of Canal Park in Lake Superior are the remnants of the Whitney rock crushing enterprise, visible here as a small brown rectangle. The Whitney Brothers, of Superior, Wisconsin, had a sand and gravel processing business that was functioning in 1919. The concrete form that is still in the water was the dredging/crushing building.

This aerial view is one of many taken by Wayne Gatlin. Canal Park (under the jet) is in its transformative stage moving from a light industrial site to a tourist destination. Grandma's Saloon and Grill has its striped canvas tent up with the ice cream railroad car in place. The double-decker red bus is at the intersection of Morse and South First Avenue East or Canal Park Drive. The first segment of the Lakewalk will be built in 1988. Duluth-born Mr. Gatlin enlisted in the aviation cadet program in 1942. Later he flew 55 combat missions for the 360th Fighter Group in England and downed an ME-262 jet fighter. In 1948 he joined the Texas Air National Guard but eventually transferred to Duluth, where he became operations officer for the 179th Fighter Interceptor Squadron. Gatlin flew jet fighters while stationed at Duluth during the Korean War. He was the high individual scorer at the 1954, 1955 and 1956 National Air Guard gunnery meets. Gatlin served as commander of the Air Technician Detachment at Duluth, wing commander, group commander and finally chief of staff for the Minnesota Air National Guard. He logged over 6,700 military flying hours during his career. Gatlin studied photography over the years and his marvelous portraits of Guard aircraft have appeared in many publications and journals.

This image shows a view from about Ninth Avenue West and waterfront at the top right corner of the shot to First Avenue East and Second Street at the lower left corner of the shot. Duluth Terminal and Cold Storage Company is at Ninth Avenue West and Railroad Street or 400 South Ninth Avenue West. The 1892 Central High School and its clock tower occupy the block on Second Street between Lake Avenue and First Avenue East in the foreground. The Canal Park area and the waterfront warehouse districts are still very industrial. The arena auditorium will not open until August 1966, in the area still filled with scrap in the middle-top of this photograph. Railroad and Commerce streets run parallel to the hillside below Superior Street and the area is well described by their names.
