I'm curious as to what you are seeing. Job Knob is clearly at 4260' or so and the previously cut slopes go to 3400' where they converge for 850' vertical. If you then look to the northeast, on close to the same trajectory as the east most cut slope, the creek is at ~2750. So, even if you didn't go all the way down, you still get 1450' ft. If you were to drop off the apex of the existing trail's turn, which is at 3600', the linear distance to 2800' is 3700' feet. This yields an 800' ft drop over 3700' linear or about a 21.6% slope. This compares with 4600 linear for the 850 drop (18.5%)from the top of the knob to the existing "base." It is also a better drop than the 900ft vertical over 4300' linear for the fall line at Timberline (21% slope). Looking from the top to the possible northeast base, you would have 1450' over 6800 linear feet, again an overall slope very comparable to the Timberline fall line.
For another comparison, you can look at Cupp Run at Snowshoe. Per Keyhole, the top is 4560' and the base is 3180' (just over 1400 ft) over a linear distance of 6150' feet (22.6%). So, while Tory is not quite as steep as Cupp overall, the lower portion is quite comparable.
It's also interesting to note that all the vertical figures arrived at with Keyhole fall short of the vertical published by ski areas. I suspect there is some "wishful thinking" in the ski area figures, but there are also many examples of known, verified elevations (precise lake levels, for example) where Keyhole values are off by 10 to 15 feet.
So, overall, it seems to me that the 1400ft potential for Tory with a very desireable pitch is quite real. Now if they can just find about $50 million
to build it....
