It’s So Hard To Say Goodbye: Getting My Kids To Donate to the State Collections

One of the best parts of my job is sharing it with my kids—even if they don’t fully understand it. They know that I travel to state historic sites, but they think that means I work at a different place each day and have offices all around North Dakota. They often ask to come with me to help. This past spring, both my son, Calvin, and my oldest daughter, Auri, traveled with me to explore the sites I manage, and in Auri’s case, helped lead Victorian-era games on the Chateau de Morès State Historic Site’s lawn.

Recently, they had the opportunity to experience a different aspect of my work by donating items to the State Historical Society of North Dakota’s collections. 

If you are like our family and have kids the same age as mine (5 and 3 years old and 6 months), then I am sure you are fully aware of good2grow juice. Incredibly popular with kids and parents, these bottles have distinctive colorful toppers featuring well-known cartoon characters.

As parents, we appreciate that the juice is not full of sugar, and the bottle is spill-proof. (Well, almost as my wife recently found out. Pro tip: Don’t throw a full bottle down a flight of stairs.) This makes them great for car trips and road trips. The bottles are reusable, so we can refill them with water if we want. When out running errands or on road trips, our kids often pick a bottle of this juice with a character they love as their treat for that trip or for being good.

If you are aware of this phenomenon, then you may also, like us, have a massive collection of bottle toppers. We are nearing 100 of these character toppers. And believe me when I say, you can’t just throw them away! My wife has seen numerous videos where parents turn these bottles and toppers into games, such as bowling, cut off the character to make a toy, or even reuse them on a straw for a different cup—basically, try to find any use that keeps kids happy about not losing a potential toy or their favorite character. So what does this have to do with my work for the State Historical Society?

One of the highlights of my job is serving on the museum collections committee. I get to see all the great things people offer us for our collections. We can’t take all of it, as sometimes the item does not have a North Dakota story or maybe we already have a similar item in our collection and do not need another. We try to collect things in the moment, so we don’t have to hope that somebody donates them to us in the future. These bottles and toppers seemed like a good candidate. They are wildly popular now, but they may not be in the future. They are the kind of item the State Historical Society could put on display someday, and parents could explain to their kids how they loved these bottles as children and tell them about the characters they collected. The biggest trick here was convincing my kids to part with a pair of precious bottles.

When I told Calvin and Auri about my idea of donating a pair of bottles and toppers to the museum collections, they were excited. We spent an hour digging through our topper drawer (yes, I know), looking at all possible options. At first, Calvin wanted to donate one that he did not care about—a character from Cocomelon he had initially selected because it was a cartoon head. I told him it should be a character that holds meaning for him. So he selected a Mickey Mouse one, and Auri chose a Minnie Mouse one. Great selections, in my view, as they once went as Mickey and Minnie for Halloween and love those characters.

The more we discussed it, the more concerned Calvin became that he would never get to use the Mickey topper or see it again. He was also worried it might break or that the State Museum might get rid of it. It was an opportunity to explain to him how our museum’s curatorial staff collects and preserves items for future generations. I told him one day it might even be on exhibit. 

Calvin opted to switch to a character he had a duplicate of instead of his one-of-a-kind Mickey with a green hat. He chose Sonic the Hedgehog. He has been a big fan of Sonic since the second movie came out. He even has a placemat with characters from one of the animated Sonic TV shows, each assigned to a member of our family (Sonic = Dad; Tails = Calvin; Amy Rose = Auri; Knuckles = Mom). Auri changed her selection to MerCat from “Gabby’s Dollhouse.” This popular children’s show on Netflix features a girl who shrinks down to the size of a toy and embarks on adventures with imaginary cats inside her dollhouse. Auri and Calvin like the show and have their own version of the dollhouse, along with many toys to accompany it. Both Sonic and MerCat are characters who mean a lot to them.

The final bottle and topper selections earmarked for the state collections.

With the bottles chosen, the next step was to submit the paperwork for potential acquisitions. I handled this part. It is a pretty simple form to fill out. The most crucial part was sharing the history and why I thought these items should be added to the collection. While these bottles do not have a strong North Dakota story, they are items that kids all over the state will remember after they grow up. 

At the meeting, the bottles were received with great enthusiasm and quickly accepted. Our department’s Administrative Assistant Kiri Stone wrote a great note to the kids, telling them that their bottles had been accepted into the collection. For most people who wish to donate items to the State Historical Society, getting such a notification would be a thing of joy. But my kids were sad—their bottles were going away. To ease the pain, I told them we would take photos of them with the bottles so they would never forget them.

Throughout this process, I constantly explained to them the reasons why we collect items and why these remain at the ND Heritage Center & State Museum. Nobody would use their bottles, I promised. Another challenge was that the bottles would not be going on display right away, and I could not tell them if or when they ever would be. To them, it might seem like they would never see their bottles again. But good old dad had one more trick up his sleeve.

Before I could put my plan into motion, I had to give the collections team time to process the bottles. When an item arrives, it does not go straight back onto a shelf. It must be labeled, a condition report created, photos taken, and data entered into our records management system. A proper home for it also needs to be found. Once this was finished, I could enact my plan. I arranged for the kids to come and inspect the new home of their bottles as well as see some of the other cool things we keep in our collections.

This October, Research Historian Lori Nohner agreed to give Calvin and Auri a behind-the-scenes tour of the museum collections area. The kids were ecstatic about the opportunity to visit Dad’s work and also be reunited with their bottles. Lori did a great job of showing the kids around the collections. Seeing their bottles was a highlight but so was seeing a pair of nursing scrubs that belonged to their mom and their dad’s name badge from his teaching days. They also got to see some historical toys. They loved that Lori let them use her badge to buzz into collections and help her move shelves. Overall, it was the perfect way to cap off this whole experience.

The whole experience was great. I know my wife and kids got a kick out donating to the museum and going behind the scenes. We don’t often think the items we use every day and take for granted have historical value. Or we feel the need to hold on to them until they are old enough to warrant donating. Now my kids can claim to have items in a museum and may continue to share items in the future. And for readers of this post, perhaps you have something we need to better tell the story of North Dakota and its people, even if it is not 100 years old.

Monitoring Erosion and Slumping at Double Ditch Indian Village State Historic Site

Double Ditch Indian Village State Historic Site is one of the most spectacular archaeological sites preserved on the northern Plains. The village was occupied for nearly 300 years (1490-1785) by the Mandan people and was a regional trading center. The site is listed in the National Register of Historic Places for its historic significance. It’s an amazing place to visit!

Visited by thousands of people annually, Double Ditch has been a North Dakota state historic site since 1936. The village has a deep cultural connection to the Mandan, Hidatsa and Arikara Nation. Following the catastrophic 2011 flood of the Missouri River, the State Historical Society of North Dakota became increasingly concerned about the impact of erosion at the site. Large sections of river terrace edge had shifted in a process called rotational erosion. This erosion destabilized the bank, threatened a large portion of the site, including parts of the public walkway, and exposed numerous burials.

The State Historical Society partnered with the Mandan, Hidatsa and Arikara Nation, the North Dakota Legislative Assembly, and other entities to address this critical threat. Left unaddressed, erosion would have continued to advance deeply into the village, causing severe damage. An engineering plan was developed and put in place to stabilize 2,000 feet of the riverbank from the effects of the 2011 flood. Appropriations made in 2013, 2015, and 2017 by the North Dakota Legislative Assembly moved this important project forward to save Double Ditch from further damage. Bank stabilization began in July 2017 and lasted about five months. The State Historical Society and the MHA Nation leadership cooperated to follow state laws and recognized cultural practices of the Mandan people while completing this sensitive work. Archaeologists from the State Historical Society were on hand daily throughout the construction period, monitoring all earthmoving activities.

In 2023, State Historical Society staff and visitors to Double Ditch noticed areas of slumping along a walking path and terraced area that was within the previously stabilized area. Archaeology & Historic Preservation Department team members immediately began to monitor the area through regular visual inspection and began documenting the progression of the slumping using uncrewed aerial vehicles (drones).

Drones have allowed us to document the extent of this dramatic slumping from the air and to consistently make detailed measurements on the length and breadth of the cracks that now cross the terrace at Double Ditch. Unfortunately, these cracks are quickly growing and represent a threat not only to the previously stabilized area but also to the undisturbed village features on-site. There is a significant possibility that the village features could be profoundly and disastrously affected if these cracks are left unaddressed.

To determine how quickly the slump at Double Ditch is progressing, we needed to look below the surface. Beginning in December 2024 and January 2025, a geotechnical drill team began to install an array of sensitive instruments to tell us how quickly the slump movement was occurring beneath the ground surface. These instruments, called vibrating wire piezometers and slope inclinometers, are used to measure water pressure and lateral movement within the 75-foot-deep holes they’re installed in. Additional instruments were installed in August 2025. These instruments will help us better document the extent of the erosion and slumping. State Historical Society staff will also continue to monitor the area from the ground and the air, partnering with the Mandan, Hidatsa and Arikara Nation, the North Dakota Legislative Assembly, and preservation groups to use all available information to address the threats posed to this important place.
