PDD Geoguessr Challenges #5 and #6: Bookstores and Hidden Landmarks
PDD Geoguessr Challenge #5: Independent Booksellers of Northern Minnesota
When the days get shorter and the nights get colder, curling up on the couch with a good book becomes one of the best ways to spend an afternoon. But first you have to find yourself a good book. This GeoGuessr Challenge is all about independent bookstores in Northern Minnesota. And for the purposes of this challenge, Northern Minnesota is any city or town at or above Highway 2. (more…)
PDD Geoguessr Challenges #3 and #4: North Shore State Parks and Duluth Neighborhoods
If you missed the post introducing PDD Geoguessr Challenges, the concept and rules are summarized at the end of this post. That first post had links for two somewhat standard challenges. In this second post, the challenges get a little bit more complicated just to show the different ways Geoguessr games can work. (more…)
Introducing Perfect Duluth Day Geoguessr Challenges
GeoGuessr is an online game that challenges people to locate specific places in the world based on the environmental cues of Streetview. The mechanics are rather simple — you move around a Streetview environment stripped of all its informational overlays looking for clues that indicate where you are. Once you think you know, you mark the spot of your original starting location on the inset map. The closer you are, the more points you get. A game consists of five locations. (more…)
Gunnar Birkerts and Intuitive Synthesis: The Place of the Duluth Public Library in the History of Modern Architecture

Duluth Public Library in the November 1980 issue of Architectural Record.
Last month, an article appeared in the Duluth News Tribune about the decision to demolish the Duluth Public Library and replace it with something smaller in a shared building. The reasons provided for demolition instead of restoration mostly involve challenges to reprogramming and subdivision created by structural pillars, expensive building systems like insulation in serious need of replacement, and other issues related to years of deferred maintenance.

Duluth Photos Featured on Twitter’s “Cars Destroyed Our Cities”
A friend let me know that Duluth recently appeared on Twitter’s Cars.Destroyed.Our.Cities (you might need to log in to see the Tweet; Twitter is undergoing some changes), an account that shows how the addition or removal of car infrastructure can dramatically change the urban environment. (more…)
The Remnants of Daniel Greysolon’s 17th Century Childhood
In two previous posts, I described how to get to the hometown of our city’s namesake, Daniel Greysolon Sieur Du Luth, and wrote about visiting his childhood home. This final post in the series shows some of the places Daniel Greysolon would have almost certainly been familiar with during his youth in the French town of St.-Germain-Laval. It concludes with a few of the more modern sites of the town. (more…)
Dinner at Daniel Greysolon Sieur du Luth’s House
A couple of weeks ago I posted an explanation of how to get to Saint-Germain-Laval, France, the hometown of Daniel Greysolon Sieur du Luth, the person after whom the city of Duluth is named. I was not entirely sure if my own trip there would happen. It did, and that post has now been updated with more accurate information and a few explanatory photos for anyone in the future who might be interested in visiting. (more…)
The Hometown of Daniel Greysolon Sieur du Lhut: A Travel Guide
Part 1: Background
About five years ago I came across the article Du Luth’s Birthplace: A Footnote to History. In 1966, the author visited the French village where Duluth’s namesake was born and documented the few traces of him that remained. The article is well researched (all the quotes from Sieur du Lhut used here are taken from it) but the images are low resolution scans of black and white photos taken more than 50 years ago. I wanted to see more of what the place actually looks like. (more…)
Mostly auto-colorized photos of Duluth and Northern Minnesota
During the pandemic, I colorized six early Duluth photos, which was absurdly time consuming but seemed like as good of a way as any to spend some evenings inside. A friend of mine recently informed me that Adobe Photoshop now has a tool that will colorize photos automatically with far better results than my drawing over pixels method. He was somewhat correct. (more…)
Duluth Reimagined: Editing Photos with AI
Previously I posted some AI generated images that could plausibly be of Duluth but it was difficult to create images that were distinctly Duluth. The absurd specificity of Jim Richardson’s interactions with ChatGPT inspired me to try again but with a different process. (more…)
Photos of an Empty Skywalk
The Duluth News Tribune recently published an article about the Downtown Task Force’s recommendations to improve conditions in downtown. This summer, I spent some time walking through the Skywalk system and was a bit shocked by how empty it was. The summer might not be the most popular time to use the Skywalk, but it wasn’t just the absence of people. So many of the shops that I remembered were gone. I didn’t intend to make a themed photo series about this, but I had my camera and kept turning a corner to find another impossibly long, completely empty hallway. (more…)
Creating Duluth-Themed Art with AI

A Van Gogh style painting of a 1920s cargo train traveling on a winter night though an evergreen forest next to a huge blue lake with the aurora borealis in the night sky.
DALL-E is an online tool that uses machine learning to generate digital images from plain English text descriptions. You type a description of something real or imaginary and the program does its best to create a unique image based on that description. After some time on a waitlist, I recently received an invite that allows me to create and download a limited number of artificial intelligence generated images per month. This came at a good time, as I recently found a watercolor print of the Duluth hillside in a Lincoln Park shop that I liked quite a bit but could not afford. I decided to use some of my AI image credits to see if I could get the automated system to produce Duluth art of at least somewhat comparable quality. In the examples that follow, I describe this process, showing what worked and what did not. The captions of each picture show the text query that generated the image. (more…)
Canal Park souvenir invites tourists to envision a lift bridge over the Mississippi
Some years ago, I had a Duluth nameplate hanging from the back of my bicycle, which I suppose is why I impulsively bought another when I saw it recently in a Canal Park souvenir shop. I vaguely remember the one I had purchased in my younger years having a generic cityscape and not actually showing Duluth.
This one seemed no different, and might even be the same design, but this time I noticed that the building on the far left had a rather specific architecture. Checking with a group of skyscraper-obsessed friends led me to a conclusion that I should have reached myself: this Duluth souvenir depicts the skyline of St. Paul. (more…)
Duluth aerial photos, then and now, compared and combined
Sometime back, I included an aerial photo in a PDD comment and realized that because they are taken from straight overhead, the photos on Minnesota Historical Aerial Photographs Online can be matched up pretty easily with Google’s current aerial imagery. And then I put that thought aside for quite some months until I finally came back to it and put together this seven-part series of aerial photos showing places in Duluth that have changed somewhat dramatically over the past decades. (more…)
Duluth on Judge John Hodgman’s Great Lakes Beach Report
The fake internet court podcast Judge John Hodgman, where pressing issues are decided by Famous Minor Television Personality John Hodgman, Certified Judge, once again mentioned Duluth, this time at length in the concluding segment of its Great Lakes Beach report. (more…)
Duluth history used to illustrate white privilege on Netflix show
In the new Netflix series Colin in Black & White, former NFL quarterback Colin Kaepernick serves as the narrator for his own story of growing up in California’s Central Valley with white adoptive parents. At the very beginning of the third episode, a modified version of a photograph taken at the 1920 lynching of Elias Clayton, Elmer Jackson, and Isaac McGhie in Duluth is used as part of a montage explaining the concept of white privilege. (more…)
The Scandia Fisheries, Duluth, Minn.
A friend of mine from Seattle was eating at Jimmy Mac’s Roadhouse in Renton, just south of “the Emerald City,” and sent the above photo to me. At first it seemed like a manufactured novelty sign because searches only returned other copies of the same sign. But then I found a Minnesota Historical Society listing for a paper crate label from the same company from around the 1950s, so it appears to have been a real business. (more…)
Artificially Perfect Duluth Day: The Microsoft Flight Simulator

Microsoft’s Flight Simulator came out on the Xbox last week and allows players to fly anywhere in the world, including Duluth. It combines information from Bing maps with an algorithm that builds 3D representations of the landscape, creating shapes and textures when data is missing or incomplete.
The video below shows a simulated flight over Park Point. (more…)
Duluth reference on the Judge John Hodgman podcast
As part of Perfect Duluth Day’s long-running quest to document every reference to the city, no matter how minor, I add this entry, discovered today while catching up on the fake internet court podcast Judge John Hodgman, where pressing issues are decided by Famous Minor Television Personality John Hodgman, Certified Judge. (more…)
Duluth area map challenges on Geoguessr
Geoguessr is a website that features variations on a rather simple game: you are shown a location through a modified version of Google Streetview. You must guess where you are by marking the location on a map. The labels and location marker normally added by Google have been removed, so you must rely on a compass and clues from the environment. The closer your guess is to the correct location, the more points you get. Each game consists of five rounds. The tops scores appear on the main page for each map, with a tie going to the player who finishes the fastest. (more…)
Duluth photos repaired and colorized: 19th century people/places


Streetcar Barn (1882)
Superior Street and 11th Avenue West
All of the photos here come from the University of Minnesota Duluth, Kathryn A. Martin Library through the Minnesota Reflections website. While most of the pictures on the site have been well preserved, some have been damaged over the years. For six of these photographs, I digitally repaired any damage and then added color. (more…)
Duluth’s Neighborhood Telephone Exchanges, 1920
One hundred years is a long time, and the Duluth of one hundred years ago can seem like a place without much connection to the present. But whether we are aware of them or not, elements of the past always carry over into the present. As an illustration of that, these five images, taken by Duluth photographer Hugh McKenzie and included in UMD’s Kathryn A. Martin Library Archives and Special Collections, show the city’s neighborhood telephone exchanges in 1920. Shown individually below, they are followed by the most recent Google Streetview image of the same location. (more…)
The Day the Brother of John Wilkes Booth Came to the Grand Opera House of Duluth

While John Wilkes Booth remains infamous as the actor who assassinated Abraham Lincoln, his older brother Edwin was actually the better known of the two prior to Lincoln’s assassination as he was considered one of the greatest Shakespearean performers of the 19th century. Edwin Booth feared that his brother’s crime would destroy his own reputation and career even though he was not only a supporter of Lincoln, but also once saved the life of Lincoln’s son by grabbing him as he fell from a train. Edwin Booth’s open expression of horror at what his brother had done led to continued public support after Lincoln’s assassination and he remained a successful actor until his death. To this day, no actor has performed the role of Hamlet more times than him. (more…)
