REPORT BY GEORGE M. DAWSON. 41 continuation of the mountainous belt of Kuy-a-kuz Lake. Its summit must be about 6,000 feet above the sea, and is quite remarkable from its symmetrical form. Seen from all points of view its outline is much the same,—a broad sloping base, like an overturned basin, with a small roughly conical peak in its centre. It is detached nearly to its base on all sides, and only approached by mountains of lower height on the south-east. Seen from the north-east, the central peak shows three distinct, though somewhat irregular horizontal lines, while lower down on the flanks are step-like prominences showing against the sky, and dim lines across its front; all suspiciously like old water marks, repre- sented either by the remnants of gravel benches or by erosion of the rocks. In the gap immediately east of Toot-i-ai, distinct flat-topped terraces are seen at an elevation estimated as 800 feet above Na-tal- kuz Lake, or 3,460 feet above the sea. (See Plate IIT.) Na-tal-kuz Lake, lying north of Toot-i-ai Mountain, is Y-shaped, the two branches running westward, while the stem narrows to the place at which the main Nechacco River flows out, and points directly east- ward. The distance from the eastern end to the head of the southern branch is nearly six miles, and from the same place to the head of the northern, eleven miles (by Mr. Cambie’s survey). The extreme width, measured just before the divergence of the branches, is about two and a- half miles. The southern arm receives the drainage of Tetachuck Lake and the Kes-la-chick River, while the northern is continued by a great series of lakes and rivers, surveyed by Mr. Cambie after the time of my visit. From a prominent rocky hill, about 300 feet above the general level, a good view of the lake and its surroundings was obtained, and a topographical sketch made. The south side of the lake and of its south arm, rises pretty steeply to a height of 100 to 200 feet, and the surface then only slightly gains in elevation as it runs back toward Toot-1ai. Some meadows and hill sides with fair grass occur, but the greater part of this bank is densely timbered with tall straight trees of scrub-pine, birch, and poplar. The valley of the south arm is continued westward by low country, and through it, at a great distance, the mountains of the Coast Range are visible. The point between the north and south arms slopes also rather steeply from the water toa flat or slightly rounded summit. Beyond it, blue hills at a distance of twenty to thirty miles close the view. The valley of the north arm turns northward, and from this point of view appears closed by a rather remarkable square-topped mountain, which must rise more than 1,000 feet above the water level.
