I'm a little late for this thread, but I thought I would post some old images of the Flooded Mine:

Also, a 1981 Silver Dollar City Tennessee map. This illustrates how the park has grown over the years, as kamikazekurve pointed out above. The map features several removed rides and attractions - The Log Flume, The Butter Churn (Trabant), The Yo-Yo Swings, The Cloud Grabber (Six Flags Skyhook), and the Saloon.
Dollywood has quite a bit of history, though you don't seem to run across much about the park prior to the big rides.
