What great photos Mel! I hadn't heard of this amusement park either. It'd be great to know more info.

White City

On the last day of June 1906, Oatka Park opened on Park Point between Thirty-Ninth and Fortieth Streets. Reports claim ten to fifteen thousand people enjoyed the park on its first day even though the park had little more to offer at the time than a public dance pavilion.

Soon after, the park became White City, an amusement park operated by the Duluth Amusement Company. In 1907 the Duluth Evening Herald credited the aerial transfer bridge with the park's existence; the old ferry system could never have carried as many people as crowded into White City on weekends. On more than one Sunday in 1906, crowds using the aerial bridge to reach White City surpassed the record of 32,595 set the very first Sunday the bridge opened to the public.

Rides were added, including the "Mystic River" boat ride, a miniature railroad (operators claimed it had the smallest steam locomotive in the United States), and the "Fun Factory," where ticket payers lost themselves wandering on twisted paths and "[ran] up against all kinds of funny and startling adventures."

Other attractions included an automated baseball game, a Ferris wheel, a water slide, free acrobats and burlesque performers, sitting rooms (for the ladies), cafés and restaurants, bathhouses, swimming lessons, and vaudeville acts. The park also featured a corral of deer, and at one time its owners commissioned the construction of a $7,500 gasoline-propelled airship to be named Duluth No. 1, although it was never built.
 
After a brief name change to "Joyland" in 1908, the park shut down in 1909. Part of the property on which it stood became the home of Maggie McGillis—in fact, a portion of McGillis's home, at 4010 Minnesota Avenue, is made from White City's old band shell.

I worked out at the Park Point Amusement park in the summers of 1960 and 1961.  The park was operated by H.C. and Mae Onsgard.  In 1960, we had the bumper cars, carousel, chair-o-plane, kiddie cars, and a real steam locomotive (Chance-Ottaway engine) ride on a small track.  There was also a small penny arcade and a snack stand with a huge concrete ice cream cone on top of it.  The carousel was what I ran, it was a 1906 Alan Herschel 36 horse carousel, all the horses were hand carved wood.  The carousel and the bumper car ride were owned by the city. The other rides were owned by the Onsgards. Originally the carosel had been steam powered in its original configuration.  The bumper cars were in terrible condition and the building was pretty dilapidated.  If you bumped the cars, the steering chains would fall off the bottom, and two or three of us would have to tip the cars over on their sides and put on the chains, a greasy job at best.  We made .50 an hour, working 10 to 10, seven days a week. All the carousel poles were brass and had to be polished every morning, an hour long job.  It could get pretty cold out there in the early mornings and after sunset in the evenings.

Looks good Tony. Small nit to pick  

This 
"Duluthian Charlie Willis earned fifty cents at the park during the summers of 1960 and 1961,"...

probably should be

"Duluthian Charlie Willis earned fifty cents an hour at the park during the summers of 1960 and 1961."

What your mom said was true. The amusement park was open through 1964. My dad, my uncle and a few others opened the original skyport at the end of the point. My dad knew the Onsgards and did many mechanical favors for them at the amusement park so my sister and I got to ride for free throughout the early 60s. The rides were in pretty bad shape at that time but were still fun for little kids. The bumper cars, train, airplane swings and kiddie cars required almost daily repairs due to their condition and so much sand blowing into critical parts. The Onsgards tried so hard to keep the dream alive but it finally died in 64. Haven't been there in many, many years so I don't know what, if anything was preserved. I just know it was a fond memory for me. I'm sure I still have at least one picture of me in the kiddie cars buried in a box somewhere!
