EXTENT OF THE DENVER. 197 



Mr. Eldridge describes, and which naturally runs as a contour for some dis- 

 tance <m the intermediate ridges. In following any one of these branches 

 of Gate ('reek it is found to have eut down into the solid rock, forming 

 a little gorge Or ravine in which the strata may be seen almost contin- 

 uously t'nr miles. This is specially true of the upper and middle portions, 

 for in the lower the Pleistocene sometimes obscures everything for con- 

 siderable distances. 



The High-Line ditch crosses the country so low down that it is largely 

 excavated in surface deposits, yet it cuts through them in many places, 

 always revealing the Denver beds below. 



Between Gate Creek and Cherry Creek is a broad, high ridge 

 extending up to East Cherry Creek, on neither slope of which are there 

 any noteworthy outcrops known. The surface is smooth, with gravel 

 abundant in places, originating from the destruction of the bottom grits of 

 the .Monument Creek formation to the southward. 



On Cherry Creek slope the line between the Denver and Monument 

 creeks is found at about the same horizon as on (bite and Murphy creeks. 

 This line crosses East Cherry < 'reek at a point about 5 miles from its 

 junction with the main creek and is indicated by outcrops of Denver 

 sandstones shortly below the reddish (days of the Monument Creek, as in 

 the region to the east. In the southern branch of East Cherry ('reck, 

 entering it on about the line between sections I'll and 27, there is a 

 characteristic outcrop of the Denver beds at a quarter of a mile above the 

 junction, and the Monument Creek red clay is found a short distance above 

 it. On the northern bank of East Cherry ("reek, opposite the last 

 mentioned gulch, the Denver beds are found within about "_'"> feet of the 

 top of the ridge, near the head of a small gully, and above this is a thin 

 capping of whitish sandstone undoubtedly forming the base of the 

 Monument Creek at this point. 



The line between the Denver ami Monument Creek beds follows 

 nearly a contour line from Hast Cherry Creek around to the crossing of 

 Cherry Creek proper, a short distance above Parker's station on the Union 

 Pacific, Denver and Gulf Railroad. The bluffs are capped by characteristic 

 sandstones and clays of the Monument Creek, and various small wafer
