THE GRAVEL: NARY RED AND PLUG UGLY. 15 
eo 
certainty, in the place of the Little Bear River, the junction of the two having been somewhere 
near the northeast end of the Dutch Flat Diggings. The Nary Red is a narrow channel, in which 
the gravel is mostly a small, clear, red quartz, thus differing almost entirely from the gravel on 
Elmore or Gray’s Hill. The description of the region above Nary Red is, in the words of Mr. 
Colgrove, substantially this: “The Nary Red is a narrow channel which crosses Cafion Creek 
near Alta, and then spreads into a broader lake-like expansion, terminating by a slide into the 
North Fork of the American at Green River.” On the opposite side of the North Fork is a lava 
flow following nearly the same course as the present stream. To the southeast of the Nary Red 
the ground rises rapidly. 
Where the gravel range is crossed by Squire’s Cafion, the country rock is seen on each side, with 
a width of about 500 feet of gravel and tailings, in the bottom of the cafion. How much more 
slate was visible, before the accumulation of the tailings began, it is not easy to determine ; but it 
appears as if the slate did not extend entirely across, the pitch being quite rapid both on the east 
and on the west side of the narrow place. 
“Plug Ugly” is the name of the high hill between Squire’s Cafion and Bear River; it is just 
south of the Dutch Flat Diggings. The western rim in the cafion appears about 200 feet in a 
westerly direction from the outlet of the old Juniata Claim, on the upper end of Plug Ugly Hill. 
It appeared, on first inspection, as if the river here must have made a very sharp turn in order to 
include the gravel on this elevation ; but it afterwards became pretty clear that this deposit is one 
which was formed at a time when a large extent of surface, not included in the main deep chan- 
nel, was covered. Ifthe bed-rock is ever fully exposed throughout this district, a comparatively 
flat table will probably be found on the top of Plug Ugly, having a rapid descent on the northeast 
side, into the bed of the main channel. But how far back one would have to look for the com- 
mencement of the pitch it is not easy to decide, for it is clear that a considerable depth of the rim 
has been cut away at the point where the line of bed-rock was seen in the caiion. It is not so 
probable that Plug Ugly is the relic of a tributary to the main stream, for the general slope of the 
country is rapidly to the west from this point, and the drainage must have come mainly from the 
east. 
The general course of Squire’s Cafion is about southwest, and for nearly half a mile it has a 
breadth of 150 feet or more on the tailings, with a pretty steep grade toward Bear River. The 
course of this caiion was followed until the gorge became narrow, and the descent so steep that 
tailings would not collect. Here was no gravel, but a narrow gorge, with slates on both sides. 
On climbing, however, by the most direct path, to the top of the hill between the cation and Bear 
River, it was found to be capped with gravel, which could still be traced for some little distance 
down the spur. The lower end of the deposit was not very distinctly marked, small patches being 
found here and there for a considerable distance below the main mass. A little way up the hill 
from the lowest gravel seen was what appeared to be a genuine rim, inclining N. 40° E. (mag- 
netic), at the outlet of a small excavation about 150 feet long by seventy-five wide, and twenty- 
five deep, in fine red quartz gravel. This point was found to be about 175 feet below the top of 
Plug Ugly Hill, although it is probably 350 feet higher than the bed-rock at Missouri Hill, on the 
opposite side of Bear River. Separated from this opening by a narrow ridge of gravel is another 
large one, 400 feet long by 125 feet wide and about thirty deep, the quality of the material being 
the same in the two. The direction of the longer axis of the opening is N. 30° E. (magnetic), 
which is also that of the top of the hill itself. No well-defined rim was found on the Squire’s 
Caiion side of the deposit. The projecting spurs are covered with slides of gravel, making the 
total amount of this material seem, at first sight, larger than it really is ; although the main mass, 
on the summit of the hill, must be nearly or quite a thousand feet wide. There is evidently a 
large number of cubic yards of gravel in this hill, but the amount could not be estimated. At the 
time this examination was made parties were engaged in making preparations to work it exten- 
sively, by means of water brought from a ditch near Dutch Flat Station.
