Nevills Rapid is created by the outwash from 75 Mile Creek. You can see the large debris delta of 75 mile Creek from the top of the rapid and downstream about a hundred yards. Nevills Rapid was named in honor of Norman Nevills who was a pioneer in commercial boating through the Grand Canyon from 1938 through 1949. One point of interest which I stumbled upon as I walked back to camp were the remains of an old mining prospect. Looking closely at the highlighted area one can see a large rock cairn marking a section where the talus slope below has been dug out. You can view this and many other Grand Canyon panoramas, with associated maps and more complete descriptions at GCPano.org.
