I have read on a local history forum about a tunnel going under the great dam wall between Crookes Valley Park and the Ponderosa.
There is reference to it being explored on another forum but I can't seem to find it there or here??
Anyone done it or know about it? I have vague info on one entrance but can't find the other.
