TULSA, Oklahoma - Wednesday, the Tulsa Foundation for Architecture gave News On 6 a look at Mohawk Park like it’s never been seen, thanks to a very old map of Tulsa’s largest park.

Shane Hood, president of TFA, showed us a nearly 100-year-old map of Mohawk Park.

"What we have is the initial layout of what the city thought would be Mohawk Park in 1925," he said.

The TFA is a non-profit that maintains historical files of Tulsa's architectural history. Recently, they got their hands on a batch of WPA files, and in it was the map.

"This is Mohawk Park before there was almost anything," Hood said.

Back then the area was just polo fields. Lake Yahola was there, too, but back then it was just the Mohawk Reservoir.

The map may be the biggest document in the TFA archives, and Mohawk is Tulsa's biggest park – 2,800 acres created by the city in 1924.

Hood said, "The citizens of Tulsa decided this was important to them. They wanted a nice natural area a large park.”

Now it's home to the Zoo, Oxley Nature Center, a golf course and lots of unspoiled space.

What's next for the map? Some repairs, then, into storage to preserve it.
