What are you on about. I think we are all getting terribly confused here. Smurf Mountain wasnt a mine train ride, as far as I was aware, It was actually just a gentle train ride through the mountain where Volcano is located today, It went about 5mph. I remember this as I actualy went on it when I went to PKD in 1992(Hey, I was 12 years old OK)
There was also a Log Flume right next to it called Haunted River that also went through the same mountain where Volcano is now I think. from memory I think it was a rather short log ride, but it had a killer drop with one Awesome Head Chopper(yes thats right, a Head Chopper, Or even a Hand Chopper if you attempted to put your hands up) basiclly it was impossible to put your hands up on the final drop as it was that bad, I remember I actually ducked most of the way down.
