The crest of the promontory was about forty yards wide at its maximum and three yards at the minimum, with a length of three-fourths of a mile.

From the middle ridge one could look down into the river on both sides, and it seemed as if a stone could almost be thrown into each from one standpoint.

The opposite amphitheatre was perhaps one thousand feet high, beautifully carved by the rains and winds.

It was named Sumner's Amphitheatre after Jack Sumner of the first expedition.

Several of our men climbed in different directions, but all did not succeed in getting out.
