TREMBLEUR LAKE TO INZANA LAKE. From Trembleur Lake an old foot-trail follows through windfalls and muskegs, much obstructed and requiring cutting out. It crosses Inzana Creek, of some size but not navigable, 2 miles from Inzana Lake, 14 miles long, with well-wooded shores on north, but burnt over to south, as far as Tachie, windfalls being thick and making travel difficult. There is a good stand of pine just west of Tchentsut Mountain, 4,420 feet, east of the trail from Trembleur Lake. Though stands of fir occur on Stuart, Trembleur, and Tezzeron Lakes, it ceases suddenly to the north. Fair stands of spruce occur north of Inzana Lake, north-east of Kazchek Lake, and north-east of Rice Lake. At about 3,200 feet some open spots occur, supporting luxuriant vegetation in hills north of Inzana Lake, and at west end of the lake are a few pockets of soil which may eventually be used, now too remote for surveying. An extensively fairly flat area extends south-eastward from Inzana Creek to Tachie. Seen from Tchentsut Mountain it seemed capable of holding a good deal of arable land, but where the trail crosses most of the opens appearing like meadows from the hill proved to be muskegs. TREMBLEUR LAKE AND MIDDLE RIVER. Trembleur Lake is in a transverse valley. Middle River connects it with Takla Lake, sluggish, navigable, with valley 2 to 6 miles wide; undulating and rolling country between rocky hills on either side, with about 120,000 acres surveyed, light sandy loam, mainly timbered with small poplar, pine, spruce, and willow. Large willow bottoms occur in valley of Natazutlo Creek, and much of remainder, burnt over about fifty years ago, has small second growth. To north of this creek are areas of scattered poplar and beaver cuttings. An Indian farm near 55th parallel on Middle River produces good potatoes and vegetables. To west of Middle River is country tim- bered with heavy spruce and willow, rising shortly to foot- hills of Middle River Range. The surveyed area east of Trembleur Lake is similar undulating land to that in Middle River Valley, draining to Trembleur Lake by creeks from hill-slopes to east and north. Kazchek Lake, 2,670 feet, drains through Kazchek Creek southward to Middle River, and a trail traverses country strewn with windfalls, intersected by mumerous muskegs, and through a stand of good spruce before reaching the lake. The trail is difficult and requires cut- ting out. At east of the lake is a large low flat, extend- ing around north-east side. There are small patches of good-looking poplar country north of Kazchek Lake. A foot-trail runs north to Kloch Lake through hill country. A low-lying tract extends north of this lake toward west end of Nation Lakes. Indians have canoes 14
