In like manner, the Green river has done the same thing, only on the upper reaches of the Green river, I should say that part immediately below Green river, we have softer sediments which have been eroded down with greater ease. the result is, we have less precipitous banks to our streams, and the river is more accessible for some distance down the entire lower reaches, and both streams have canyon walls which are very precipitous. Again we find foldings of the earth -- of the sediment at various places -- which have formed archings of the rocks on the surface.
