Chickasaw NRA — The Lost Calendar
You are Douglas Henry Luper, founding mayor of Chickasha in 1898, tasked with recovering the sacred Chickasaw calendar, lost during the city's founding.
Your quest
Follow in the footsteps of railroad pioneers and the founders of Chickasha, a city born from the Oklahoma Wild West epic.
The story that haunts this land
Your journey begins at the Grady County Historical Society Museum, located at 420 W Chickasha Ave, Chickasha, OK 73018. This historic downtown building, founded in 1898, houses essential artifacts for understanding the early days of Grady County. As Mayor Luper, you search here for the first traces of the calendar before heading to the Chickasha Public Library. Built in the 1920s, this library is a landmark of the Downtown Chickasha Historic District, where events like a 'Library Escape Room' are even held on July 17, 2025, highlighting its continuous role in Chickasha's cultural life.
Continuing your investigation in Oklahoma, you proceed to Troutt Hall, a historic building on the University of Science and Arts of Oklahoma (USAO) campus, founded in 1908 as the Oklahoma College for Women. This site, listed on the National Register of Historic Places for its buildings dating from the 1910s-1930s, is about 1 km from the starting point, in the university district adjacent to downtown Chickasha. Here, you explore university archives, hoping to find hidden clues about the calendar's location, before returning to the heart of the Downtown Chickasha Historic District.
The Downtown Chickasha Historic District, listed on the National Register of Historic Places in 1982, covers 1.5 sq km and includes over 100 buildings erected between 1898 and 1945. This nerve center of Chickasha, with its main shopping street, is the setting for your search. The Chickasha Murals, on downtown buildings, celebrate local history and the Chickasaw, and have been part of public art initiatives since the 2010s to revitalize this historic district. Here, you decipher symbols that could guide you to the next step of your quest.
Your route then takes you to Legion Park, a public park located about 800 m from the starting point, commemorating veterans. This community gathering place, with its green spaces and monuments, offers a welcome break before you delve into Chickasha's railway past at the Rock Island Depot. This former Chicago, Rock Island and Pacific Railroad station, built in 1900 and restored as a railway museum, testifies to Chickasha's major role as a Rock Island Railroad hub in the early 20th century. Edward B. Johnson, a key railway promoter, would certainly have appreciated this stop.
Finally, your investigation leads you to the Old Post Office, built in 1935 in the PWA Moderne style, less than 500 m from the museum. This example of 1930s federal architecture, also in the Downtown Historic District and listed on the National Register in 1982, could contain the final pieces to reassemble the lost calendar. This walking thematic circuit through Chickasha, focusing on its heritage and Rock Island Railroad history, will have allowed you to discover Oklahoma's monuments and understand what makes this interactive visit to Chickasha so unique for families and history enthusiasts.
