Bebb's original design consisted of a massive stone tower topped by a circular platform and fire observation cab, and accessed by a concrete ramp. Fred Arnold, head of the park service's Forest and Wildlife Protection branch, rejected the inclusion of the fire observation cab, arguing that while Clingmans Dome was the highest point in the park, it wasn't particularly useful for fire detection purposes. Park service director Conrad Wirth objected to the use of a ramp, favoring instead a spiral staircase. After John B. Cabot, head of the park service's Eastern Office of Design and Construction, convinced him of the ramp's usefulness, Wirth decided the stone tower would not be necessary, stating a single central support column would suffice.
