Today’s postcard from a 1940 Oklahoma souvenir pack is from what was once Platt National Park. The image is of Bear Falls, a surprising choice to me given the other opportunities there of Sulphur’s artesian Vendome Well, the old mineral water fountains, or Lincoln Bridge. I believe that flood damage eroded away some of the upper layers of the falls dam over the decades since the postcard image was taken.

I have been to the park many times, but I don’t recall ever photographing Bear Falls, which vary seasonally with the level of Travertine Creek. So I draw upon the photographs shared by others in recent years.



The park was pretty small in 1941. Those who study the map below will see that a State Tubercular Hospital used to be adjacent to it; that 1921 facility is now the Sulphur Veterans Home. It is about 3,000 feet southwest of Bear Falls.

When I visit the area, I’m much more likely to visit Little Niagara farther upstream, which has upper and lower falls. When I was a kid, my parents usually camped in their Yellowstone trailer over in the Rock Creek campground at the west end of the park. It was near the Buffalo Pasture, which had a small herd of bison brought over from the Wichita Mountains Wildlife Refuge in the 1920s. In 2023, the recreation area shifted the small herd from the 84-acre pasture used since 1934. The old pasture had built up too much woody overgrowth, and a new 42-acre one offered better grazing. There are plans to use both pastures over time to allow for prairie restoration and maintenance.

When I was an adult, my father and I once camped at the park in one of his Volkswagen campers. We rode our bicycles eastward for miles along Perimeter Road to visit Little Niagara. I have fond memories of a local bluegrass instrumental group performing at the Travertine Nature Center at the east end of the park.
The CCC at Platt constructed five dams along the creek, including one at Bear Falls and the lower dam at Little Niagara. One of the falls at Bear Falls and the upper dam at Little Niagara appear to have been natural features, although there is evidence of some concrete work at the upper dam of Little Niagara.
Farther downstream along Travertine Creek, just before it empties into Rock Creek, is Lincoln Bridge, which was built in 1909 on the centennial of Abraham Lincoln’s birth as the first major improvement in the park, seven years after the federal government purchased 33 mineral springs from the Choctaw and Chickasaw nations to create the Sulphur Springs Reservation. It was renamed Platt National Park in 1906 in honor of Senator Orville Platt of Connecticut, who had helped establish the area.
Platt was not a very big national park, but it attracted people with its “healing waters” which came out of the ground cold at about 63 degrees Fahrenheit. A 1941 park booklet, published about the same time as the postcard, addresses Pavilion Springs, Bromide Spring, and Medicine Spring. The most significant sulphur springs in the park are Hillside, Pavilion, and Black Sulphur Spring, which still flow, although Hillside and Black Sulphur have bacterial contamination and are no longer safe to drink. The major bromide springs were Medicine and Bromide, but those have stopped flowing.
After World War II, Platt became more popular, hitting one million visitors for the first time in 1949 as people were now more attracted to recreational and outdoor opportunities than water cures. The Lake of the Arbuckles was constructed in the 1960s in the Arbuckle Recreation Area, and in 1976 that and the old national park were combined into the Chickasaw National Recreation Area that is mapped below. To get your bearings, Cold Springs Campground at the upper right is where Bear Falls is located.

The water cure movement was long gone, vanquished by modern medicine, and Platt was demoted since it was small and lacked scenic grandeur. The act was part of my education in the frequent humbling of my home state.
My favorite attraction is Bromide Hill near the Rock Creek campground where my parents often camped. That long mound of conglomerate rock rises 140 feet above Sulphur and the park. For millennia rivers washed rocks down from the Arbuckle Mountains and lime in the water cemented them into what is now Bromide Hill, which is tall enough to transition from oak, ash, and elm trees into short grass and prickly pear cacti. An overlook provides a great view of Sulphur and is called Robbers Roost since local legend says outlaws once used the location.
The Vendome Artesian Well was drilled in 1922 about eight feet outside the park’s main entrance, and it produced 2,500 gallons of water per minute from the Arbuckle-Simpson aquifer due to hydraulic pressure. It became part of the recreation area in 1979, and in 1998 a new well was drilled about 20 feet west of the original one, featuring a steel casing to resist corrosion. Visitors may safely drink from it, but most of my friends have declined to do so thanks to its distinct aroma of hydrogen sulfide.

Interestingly, the chloride-to-bromide mass ratio of its water suggests that the 1% of its output that is brine is a product of evaporated seawater from ages ago. The groundwater flowing from the well is about 10,500 years old by Carbon-14 dating, which is quite different from the freshwater springs and wells flowing from unconfined portions of the aquifer.
Wendy and I enjoy visiting Sulphur, where we stay in one of the special suites at The Artesian Hotel, which is run by the Chickasaws. We eat in its Springs at the Artesian restaurant and browse its shops, purchasing some of the tribe’s Bedré Fine Chocolate treats.
Tomorrow’s postcard will take us much farther south, to Lake Murray.
