 Plate 48 — Veta Peak, Colorado, and the North Rock Stream 



Figure 1. — General View of the north Rock Stream, looking East. 



The view is talien from a point about 500 feet above the level 

 of the lower end of the rock stream. In the distance is the ridge 

 of North Veta Peak to the left and of South Veta Peak to the 

 right, with the notch between. At a is the top of the landslide 

 that developed into the rock stream. The south branch of the 

 rock stream started between a and J). The sparsely wooded hill 

 in the foreground is composed of red shales and standstones of 

 Carboniferous age. 



Figure 2. — Nearer View of the Source of the Rock Streams. 



These streams started as two landslides, one at a and the 

 other between a and h. In the foreground to the left is a por- 

 tion of the north branch, showing steplike rock billows. 



Plate 49 — The North Rock Stream 



Figure 1. — View of the middle Portion of the Rock Stream. 

 B The view is taken at the point where the north branch and 



the south branch unite, showing the longitudinal ridges and 

 troughs. 



Figure 2. — View looking North across the Rock Stream. 



The view is taken at the narrowest part of the stream below 

 the junction of the two branches. The wooded slope beyond the 

 stream is Carboniferous. The view also shows several flat ridges 

 and intervening troughs.

Plate 50 — The North Rock Stream 



Figure 1. — View looking up at the Rock Stream. 



The view is taken from the bottom of a flat side valley that is 

 dammed up by the rock stream. The direction of flow is at right 

 angles to the line of vision. 



Figure 2. — Detail of the Rock Stream. 



The view shows the flat and uniform sized rock fragments 

 standing on edge in the bottom of one of the troughs.
