Donovan said:Cripple Creek, along the old "ditch" or pipeline grade for the hydraulic excavation and back filling of the Oak Grove Project pipeline?

That is what I was going to guess.  This looks to me like the area just past the "hillside meadow" if my memory serves me.....

Donavon is correct, it is the Cripple Creek Trail along the 'ditch grade'.

Is that the section right past the meadow?  Or is it somewhere else on the trail?

It's at the top of the second rock field. Distinctive for width and it's perfectly level.

Here comes my next picture.

Rob it is the section just above the rockslides down lower on the trail. The "ditch or pipeline" section is real wide and almost flat, but I am sure there is a slight slope to it to cause the water to flow down the pipeline.
