382 PROCEEDINGS OP WASHINGTON MEETING. 



1293 (23). Falls on upper Snoqualmie river. View of falls and canyon in meta- 



morphosed grits and slates of Miocene age near the summit of the 

 Cascade range, Snoqualmie pass ; elevation 3,000 feet. 



1294 (25). Falls on Snoqualmie river. Franklin falls about two miles west of Sno- 



qualmie pass. 



1295 (34). The Needles from Poodledog pass, Monte Cristo, Washington. The 



Needles (see number 38) are composed of breccia from Twin Lake 

 crater, off to the right. An important mineral vein is the cause of 

 the ravine between them. 



1296 (37). 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 trav- 

 ersed by numerous metalliferous veins. Their elevation is 6,500 to 

 7,000 feet. 



1297 (38). Panorama from W ill man n pass (north half ), Monte Cristo. The divide 



between Silver creek, flowing south, and Sauk river, flowing north, 

 at Willmann pass is an arete with an elevation of 4,800 feet. We 

 stand on 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 continuation in 39). 



1298 (39). Panorama from Willmann pass (south half), Monte Cristo. The fore- 



ground 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. The district produces 

 argentiferous and auriferous sulphurets. 



1299 (40). Glacier peak, Monte Cristo. View from the same point as number 39 ; 



taken with a narrow angle lens to show details of Glacier peak. 



1300 (41). Glacier peak from Goat peak, Monte Cristo. We stand on the ridge 



between the crater basin of Twin lakes on the right and the glacial 

 amphitheater leading down to Monte Cristo on the left, looking east. 

 The rocks in the foreground are granite. The mass of Glacier peak, 

 including the near high ridge, is composed of volcanic breccia. The 

 contact between the two occurs along a vertical plane immediately 

 at the foot of the first ascent from the foreground (see 52). The 

 flows from Twin Lake crater are distinctly bedded and dip eastward 

 (see 43). 



1301 (43). Cliffs of porphyrite and breccia, Glacier peak, Washington. View from 



the same point as 41 ; taken with a narrow angle lens to show details 

 of bedded and vertical structure in flows from Twin Lake crater. 



1302 (45). Looking west from Goat peak, Monte Cristo. View of Silver Lake and 



Silver Tip mountain a mile and a half southwest of Monte Cristo, 

 Washington. The rock of the vicinity is a massive volcanic. The 

 lake occupies a basin, which is presumably a crater, but which may 

 possibly belong to the class of hollows produced by retrogressive 

 glacial erosion. Attention is called to the extremely abrupt peaks 

 characteristic of this portion of the Cascade range.
