How steep, what is the elevation from bottom to top?

It's probably equal to the 2 setting on a tread mill. Steep enough to feel it, but a kid or healthy older person could walk it easily. Elevation is about the same as the top of the Gorge: 850 off ft

Top is 850ft. Not steep, as it is platform switchbacks most of the way up. Slow and steady. No problem. Weekdays have less foot traffic, so less stopping to allow others to pass. Fantastic view from the top. Enjoy.

It's a switch back so you don't feel the elevation as you are climbing. It's about 980ft? You can do it just take your time : )
