Rouse : I S mi x 600 yards ; I've 't high ; with precipitous sides ; few indented quartz brecciated Group. I have not found a single rock in the whole of this remarkable area. The only rocks which I have seen are covered with crusts of salt and gypsum, and these are so thick that it is impossible to determine their nature. The only water which I have found is in a small stream which flows from the mountains on the north-east side of the range. This stream is very clear and cold, and contains no fish or other aquatic life. I have also seen several springs of hot water issuing from the ground near the base of the mountain. These springs are very strong and boil over with great force. The only vegetation which I have seen is a few patches of grass growing on the slopes of the mountains. There are no trees or bushes anywhere in sight.
