"While sitting on the south side of the monument at twelve o'clock, we put the thermometer in a favorable place, and it went up to 84°. At the same time, on the north side, and six feet from us, water was freezing, and the snow dry and crusty. Near by the monument a rock stood in its natural position, having a sharp peak in the top. This was the highest one of the kind. Of this about four inches were broken off, and one of the company carried it home with the conviction that we had lowered the height of Ktaadn to that amount. About two P.M. we returned to the eastern peak. It may be well to pause here and take a re-survey of the scene thus far presented, and as much more as can be viewed from this point. "From this eastern peak a spur makes out eastward one mile. Half a mile down, however, it divides, and a branch runs to the northeast the same distance. On the southwest, across the cut, is the 'Chimney.' From this the line of peaks and hammocks curves to the west till it reaches the middle and highest peak. From one hammock to the other there are, in all, thirty rods of narrow passes. Some of them are so narrow that a man could drop a stone from either hand, and it would go to unknown depths below. In some places the only possible way is over the top, and only one foot wide. For a great part of the time the wind blows across these passes so violently that the stones themselves have to be firmly fixed to keep their places. It seemed remarkable, as if for our convenience, that the day of our visit was still and quiet. From the middle peak the line curves to the northwest, to the further monument. From this point a branch makes down to the southwest, having on it some extensive table-lands, while the top ridge or curve turns directly north with the '_sag_.' At the bottom of the '_sag_' we come upon a wide flat, which runs north half a mile, and stretches out to a considerable width. At the northern extremity of the flat the ridge curves to the east, and rises to a peak about equal in height to the eastern peak of the northern wing. This is probably the highest of the northern peaks, from which a spur makes down, a little south of east, to within one quarter of a mile from the one that comes from the southern wing. All this nearly includes a deep basin, with walls almost perpendicular, and in some places apparently two thousand feet high. "To survey the bottom of this basin I have since made a separate journey. It contains perhaps two hundred acres, covered with large square blocks of granite that seem to have come from the surrounding walls. There are in all six lakes and ponds, varying in size from two to ten acres. One of them I crossed on ice the 15th of October.
