The Orari.

Between the Rangitata and Opihi rivers the Orari system is situated. It drains the high ranges which, from the Two Thumb range, branch off in an easterly direction along the southern banks of Forest creek and Rangitata, below the junction of the former tributary. The different head branches, the Hewson, Mackenzie, and Orari streams, of which it is formed, and the main river below their junction till it has passed the Mount Peel range, mostly flow in gorge-like channels. Once entered upon the plains, the bed widens very soon and forms a broad shingle course.
