1238. East end of lake Chelan. Detailed view of drift dam, showing cross-strati- 



fied sandy clays covered by till, gravel, wash, and turf in ascending suc- 

 cession. Between the till and the cross-stratified sands are pockets of 

 coarse gravels and boulders, which probably correspond to stream chan- 

 nels (No. 193). 



1239. Lake Chelan and outlet. General view of the drift dam and the site of 



Chelan (No. 194). 



1240. Carbon Eiver glacier, mount Rainier. View from the eastern lateral moraine 



of the Carbon River glacier, showing the sweep of the ice as it descends 

 from beneath the great northern amphitheater of mount Rainier. In the 

 foreground the slope of the lateral moraine toward the glacier shows how 

 extensively it has lost in volume, and the ice is covered with morainal 

 material (No. 16). 



1241. Flora east of Carbon River glacier, mount Rainier. August flora on the edge 



of the Carbon River glacier (No. 14). 



1242. Ice cascades, head of Carbon river, mount Rainier. View in the great am- 



phitheater, the gathering point of the Carbon River glacier. On the left 

 of the picture the cliffs rise 6,000 feet to the Liberty cap and the glacier 

 * flows out to the right (see number 1240) (No. 17). 



1243. Jointed granite, Denny creek, Snoqualmie, Washington. Glacial amphithe- 



ater eroded in the granite. The streams of this portion of the Cascade 

 range descend by a series of steps, each of which is attributed to the retro- 

 gressive work of glacial action (see number 1245) (No. 55). 



1244. Falls on upper Snoqualmie river. View of falls and canyon in metamor- 



phosed grits and slates of Miocene age near the summit of the Cascade 

 range, Snoqualmie pass; elevation 3,000 feet (No. 53). 



1245. Falls on Snoqualmie river. Franklin falls about 2 miles west of Snoqualmie 



pass (No. 52). 



1246. The Needles from Poodledog pass, Monte Cristo, Washington. The Needles 



(see number 1248) are composed of breccia from Twin Lake crater, off to 

 the right. An important mineral vein is the cause of the ravine between 

 them (No. 33). 



1247. Pride of the Mountain range, Monte Cristo. This range lies east of Monte 



Cristo, separating that district from the Goat Lake district. A portion of 

 the high peaks consists of diorite, and they are traversed by numerous 

 metalliferous veins. Their elevation is 6,500 to 7,000 feet (No. 34). 



1248. Panorama from Willmann pass (north half), Monte Cristo. The divide be- 



tween Silver creek, flowing south, and Sauk river, flowing north, at Will- 

 mann pass is an arete with an elevation of 4,800 feet. From its crest, 

 looking northeast. Monte Cristo, the mining camp, lies in the canyon in 

 front of the farther range. The Needles and Willmann peak, composed 

 of breccia from Twin Lake crater, rise in the right of the picture (see con- 

 tinuation in 1249) (No. 19). 



1249. Panorama from Willmann pass (south half), Monte Cristo. The foreground 



shows the descent into the '"76" amphitheater leading to Monte Cristo. 

 The high peak in the center is Glacier peak, on the right of which, in the 

 basin 2,500 feet deep, lie,Twin lakes. A small glacier extends northward 

 from the peak (No. 18).
