Yellowstone Lake
formerly called SUBLETTE'S LAKE, a beautiful lake in Wyoming, at the N. E. base of the Rocky Mountains; in the National Park of the Yellowstone, at an elevation of 7,788 feet above sea-level. Its greatest extent is about 20 miles, and its greatest depth 300 feet. Its outlet is the Yellowstone river, which issues from the N. end of the lake. The Upper Yellowstone river enters at the opposite side. This lake is surrounded on several sides by high mountains, among which are Mount Sheridan and Mount Langford .
YELLOWSTONE NATIONAL PARK, a remarkable region in the extreme N.
W. corner of Wyoming; set apart by Congress for a National reservation in 1872. Its area was originally 3,575 square miles, to which Congress, in 1891, added a tract of nearly 2,000 square miles to the S. and E.-nearly all more than 6,000 feet above sea-level, and rising in the snow-covered mountains to on the 10,000 to 14,000 feet. Situated on the "Great Divide," its pine-clad mountains form the gathering ground for the headwaters of large large rivers flowing away to the Atlantic and Pacific Oceans, and for the sake of the rainfall and the rivers its forests are carefully preserved.
The mammoth hot springs are of a class with those in the geyser basin.
The element of beauty enters into the formations from the deposits left by the water .
These have been built up by ages of activity, and are in scalloped terraces.
Their greatest activity is manifested at the base of Capitol Hill, on the picturesque bank of the Gardiner river . But there are unmistakable evidences of their activity for miles back, for cedarcrowned mounds yet yield treasures to the tourist who seeks specimens with a well-directed spade. In walking over some of the terraces where the water has ceased to run, the formation sounds hollow underneath, the action of the elements having built the terraces at the expense of the limestone beds below the surface. Caverns have been found surface.
Caverns have been found underneath the now inactive basins, which are resplendent with stalactite and stalagmite formations that glisten under the blaze of a torch with singular brilliancy.
YEMEN ("the land to the right of Mecca"), a district in the S. W. of Arabia, bounded on the N. by Hedjas and on the E. by Hadramaut, and measuring about 400 miles in length by about YENIKALE miles in breadth. At about 30 miles from the coast a range of wooded mountains (rising occasionally to 6,000 and 8,000 feet) stretches along the whole length of the country. Between this range and the sea stretches the scorchingly hot plain called Tehameh. Further inland the country becomes an elevated plateau. Though destitute of rivers, the the whole region region is very fertile, and coffee, tobacco, dates, gums, and spices are produced and exported in abundance. There are valuable pearl fisheries on the coast. The inhabitants are Arabs, but possess many distinctive characteristics, and are supposed to be descended from the ancient Sabæans.
