By that I mean the Colorado river has entrenched itself to a great depth; there side streams have worked their way and out their way down to the same level as the Colorado river. " 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 case. " The result is, we have less precipitous banks to our streams, and the river is more accessible for come distance down the entire lower reaches, and both streams have canyon walls which are very precipitous.
