to twelve inches wide, from which steam issues in considera- 

 ble quantities. The inner portion of the shell is lined with a 

 hard, white enamel like porcelain, covered with beautiful 

 crystals of sulphur that have been gathered from the surg- 

 ing and seething cauldron of sulphureted steam rising from it.

 portion.

No. 227. Cap of Liberty, near view. 



At the base of the principal terrace is a large area covered 

 with shallow pools, where some of the ornamentations are 

 perfect, while others arc fast going to decay, leaving the 

 decomposed sediment as white as snow. On this sub-ter- 

 iace is a remarkable cone about fifty feet in height, and 

 twenty feet broad at the base, its form suggesting the name 

 of the Liberty Cap. It is undoubtedly the remains of an 

 extinct geyser.

 Looking down upon Gardiner's River from the summit of the 

 main terrace, the beautiful basins forming the foreground, 

 and rising abruptly from the river to a height of from 1,600 

 to 2,000 feet, is a vertical bluff of beautifully stratified Cre- 

 taceous and Tertiary beds, capped by a basaltic plateau.

THE FIRST BRIDGE EVEB BUILT ACROSS THE YELLOWSTONE, 

 near the junction of Last Liver with the Yellowstone, and 

 about fifteen miles above the Hot Springs. It was built 

 by miners in the summer of 1870, to accommodate the "stam- 

 pede" that set in toward the Clark's Fork "diggings." The 

 river is here 200 feet wide, and 6.0WS with great force and 

 rapidity between perpendicular walls. 



No. 233. Tower FALLS, near view from near its base. 



No. 234. Tower Falls, distant view from above. 



Fifty miles above Iiotclci's we reach the deep, wild, roman- 

 tic gorge through which Hows Tower Creek. It rises high up 

 in the main divide, back of Mount Washburn, and Hows for 

 about ten miles through gloomy canons. About 200 yards 

 above its entrance into the Yellowstone the stream pours 

 over an abrupt descent of 156 feet. The falls are about 260 

 feet above the level of the Yellowstone at the Junction, and 

 are surrounded by columns of volcanic breccia, (Nos. 235, 

 236, and 237,) rising from 50 to 100 feet above the falls, and 

 extending down to 'their toot, standing like gloomy sentinels 

 or like gigantic pillars at the entrance to some grand temple. 

 They form the most conspicuous feature of the scenery, and 

 suggest the name given to creek and falls. 



No. 238. Column Rocks, on the east bank of the Yellowstone, a short 

 distance below the mouth of Tower Creek, and forming one 

 side of a deep narrow canon. The walls are about 000 feet 

 in height, and have two rows of basaltic columns, each one of 

 which is about twenty-five feet in height and five feet in di- 

 ameter. Between these two layers, which are 200 feet apart, 

 are beds that seem to have a large amount of sulphur in their 



composition, from their bright yellow
