A three-toed dinosaur tracksite

The world that existed when dinosaurs roamed the Moab area was vastly different than the world today. Science Moab talked with Dr. John Foster about what this region was like 150 million years ago during the late Jurassic period, when a geologic layer called the Morrison Formation was being deposited.

Foster is a paleontologist and former director of the Moab Museum. His work involves excavating the oldest known dinosaur skeleton, right here in Moab.

Science Moab: Tell us about the geologic layer you study called the Morrison Formation.
Foster: Most of the really famous dinosaurs were found in the Morrison Formation starting back in the 1870s, like Brontosaurus, Stegosaurus, Allosaurus and Brachiosaurus, which was actually first found in what is now Grand Junction. So it’s a pretty well-known formation for dinosaurs. At that time, none of the mountains were here. What is now the Rocky Mountain region was essentially flat. So the whole region that we see now, the Colorado Plateau, all the canyons, the mountains of the Rockies, all that was basically just a big flat floodplain. So it was a very different world.

Science Moab: When was the Morrison Formation being deposited?
Foster: Roughly 100 and 50 million years ago. The Morrison represents a time that’s about 7 million years long. It’s late Jurassic, but we’re lucky in that there were mountains off to the West that had a lot of volcanoes in them. That means they pumped a lot of ash into the mudstones in the floodplain and it’s because of those ashes that we can get the dates on how old the rock is.

Science Moab: What was Moab like 100 to 50 million years ago?
Foster: We’d be probably at least 100 miles or so from the mountains. There would have been rivers flowing through this area and there were also a lot of wetlands. The environment would have been not quite a rainforest or anything like that, but it was certainly a lot wetter than it is today. We have a plant study site down by Blanding that we’ve been working, and one that was found about 25 years ago down by Bluff, that show abundant ginkgoes and ferns and conifer wood and a number of different plants that are a lot more wet-adapted than plants we see now.

Science Moab: And what were the animals like?
Foster: There were a lot of animals. I think they were probably about 20 to 25 different types of dinosaurs at least. There was a diversity of the big long neck, long tail guys, some of which have been found near Moab. Among non-dinosaurs, there was everything: fish and frogs and salamanders, turtles, lizards, crocodiles, pterosaurs and about as many species of small mammals as there are dinosaurs. In total, there were a little over 100 different species of vertebrates known from the Morrison Formation. And then, of course, there are snails and clams and crayfish and other invertebrates.

Science Moab: So if we were standing right here during the Jurassic, we would be surrounded by a lot of life?
Foster: Yes, there’s a good chance we’d be standing in the mud with a lot of conifers around, a lot of little burrowing water-dwelling animals, and few dinosaurs probably in the distance. The neat thing about a lot of animals that we’ve been finding recently is that we thought they were all just little herbivores that scurried around at night, but their ecologies were not that simple. In fact, many of them turn out to be quite similar to animals around today.

Science Moab: What does it feel like to find a fossil?
Foster: Sometimes you actually do have to stop and remind yourself that this thing has not seen the light of the sun for 100 or 50 million years and you just exposed it. You forget that sometimes. But of course, every once in a while you find something really rare that shocks you. And you get really excited about that.

Science Moab: What value do you find in the study of paleontology?
Foster: I think the biggest thing is understanding the way past ecosystems function. As jealous as we get of modern biologists being able to actually see these things interacting, I think the value is in the long-term perspective on ecosystems: How they react to change and how the animals and plants really can influence the physical environment as well. Providing that long-term input on biology, in general, is probably the most important part of it.

Uranium Days 1956: The celebration

For several years beginning in 1956, Moab hosted an annual festival dubbed “Uranium Days,” which celebrated the town’s booming wealth and growth on account of uranium mining. This short-lived celebration was established to compete with events like the Green River Melon Fest and various other festivals occurring around the state. The first event was held on August 17 and 18 in Moab.

The Times-Independent reported on August 23, 1956, “Uranium days hit Moab in full force on Friday morning and were there very much in evidence until late Saturday night. It was two full days of parades, programs, dances, and merchandising events for Moab’s residents and visitors from out of town, and judging from the large crowds, and feeling of excitement from people on the street, the first of what is hoped to be an annual event was a huge success.” Uranium Days, however, would sadly be held for only four years, with the last court serving in 1960.

The inaugural Uranium Court
One of the highlights of the event was the naming of the Uranium Queen and her court. Eight contestants, each sponsored by an independent mining company, vied for the “honor of reigning over the two-day celebration,” according to the Grand Junction Daily Sentinel on August 16, 1956.

“Friday evening the festivities got underway with the crowning of the Queen,” the Times-Independent reported on August 23. The contestants would compete later in the State Dairy Princess contest at the State Fairgrounds later in September of that year.

Marjorie “Mardy” Dawn Thomson (b. 1936), Miss Standard Uranium, was named the inaugural Uranium Queen in 1956. She later married William H. Lewis in Moab. Nancy Elizabeth Nault (b. 1939), Miss Federal Uranium, was named Mardy’s attendant (left in the image) and later married Moab’s Garry Joe Day. Hallene “Hally” Thorne (b. 1939), Miss Utex Exploration, was named Mardy’s second attendant (right in the image) and later married Olin T. Glover in Moab. All three attended Grand County High School; the two attendants graduated in 1958 and the queen graduated a year earlier.

The 2023 mural
In October 2023, Dr. Chip Thomas, a photographer, public artist, activist, and physician who has been working on the Navajo Nation since 1987, installed a mural supported by the Moab Arts and Recreation Center on the Moab Museum building on Center St. The photo, a selection from the Moab Museum Collection, displays the 1956 Uranium Queen and her attendants riding a vehicle riding down Center Street in the Uranium Days Parade.

Pictured in the image are the 1st place float by Hecla Mining Co., the New Cooper Martin Building (where the Spoke currently resides), First Security Bank (at the current Wells Fargo site), the Fletcher-Robertson Building (now home to The T-Shirt Shop), and the Times-Independent building, where Desert Threads currently resides.
