The first sawmill on the site was built in 1903 by George England and Manley Wilbur, from where Wilburton gets its name.
In 1904, the town of Wilburton was platted and in 1905, the Hewitt-Lea Lumber Company took over the logging and milling operations.
It built a spur line that followed Kelsey Creek up to the Lake Hills area and brought in the town's first locomotive in 1907.
[5] The Hewitt-Lea Lumber Company logged the region between Lake Hills and the northern end of Cougar Mountain.
The sawmill buildings were located underneath the current 405 overpass near the base of the Wilburton Trestle.
