Half a mile up the Firehole, above the mouth of Spring Creek, is the _Lone Star Geyser_ (4 miles). This geyser is conspicuous chiefly for its fine cone. It plays frequently to a height of 40 or 50 feet. _Madison Lake_, ten miles further up the valley, is the ultimate lake source of the Madison River. This lake, with possibly the exception of Red Rock Lake, the source of the Jefferson, is further from the sea by direct water-course than any other lake on the globe. Returning down the Firehole, we enter the mouth of _Spring Creek Cañon_ (3.5 miles), which the road traverses for a distance of two and one-half miles. This narrow, winding, rocky cañon, under the shadow of the Continental Divide, is full of picturesque turns and surprises. [Illustration: _Terry Engr. Co._ _Haynes, Photo., St. Paul._ Lone Star Geyser.] The first crossing of the _Continental Divide_ (8.5 miles) is through a narrow cañon, _Craig Pass_, hemmed in by precipitous cliffs, inclosing a lily-covered pond, _Isa Lake_, which rests squarely upon the doubtful ground between the two oceans. [Illustration: _Terry Engr. Co._ _Haynes, Photo., St. Paul._ Shoshone Lake.] _Shoshone Point_ (10.5 miles) is in the center of the large amphitheater-shaped tract which is drained by the branches of _De Lacy Creek_. It overlooks _Shoshone Lake_ and the broad basin surrounding it, and gives a second glimpse of the Teton Mountains. [Illustration: _Terry Engr. Co._ Isa Lake and Craig Pass.] Shoshone Lake is a lovely body of water, with an area of twelve square miles and a most picturesque shore line. On its west shore is a geyser basin, second in importance only to those on the Firehole. Among its many interesting features may be mentioned the _Union Geyser_, of which the middle crater plays to a height of 100 feet; and the _Bronze Geyser_, very striking because of the perfect metallic luster of its formation. From Shoshone Point, the road again ascends to the Continental Divide, and then drops down the Atlantic slope toward the Yellowstone Valley. _Lake View_ (18 miles) is at a point where a sudden turn in the forest road brings the tourist, quite without warning, in full view of one of the most striking water landscapes in the world. The whole vista of the _Yellowstone Lake_ is spread out before him, still 300 feet below where he is standing. Far to the right and left, along the distant eastern shore, extends the _Absaroka Range_ of mountains, many of its summits still capped with snow. Every-where the dark pine forests come down to the water's edge, in fine contrast with the silver surface of the lake. The sparkling of the waves, the passage of the cloud shadows, and, in sheltered coves, the tranquil mirror of the waters, all combine to make the picture one to be long remembered.
