ings and a shaft sunk to cut the lode at depth, but no ore was found, 
and there is some doubt whether the ore-bearing vein was ever cut in 
the lower workings. 
The Black Silver, on the crest of Engineer Mountain, east of the sum- 
mit, was developed by a shaft and several tunnels run in on the north 
slope of the mountain. The lode strikes N. 38° E., and dips north- 
west at about 75°. It is 18 inches to 2 feet in width, and in general 
character closely resembles the Polar Star. Some very rich silver ore 
was formerly extracted near the surface. 
The Mohawk, on the north side of Engineer Mountain, was nut vis- 
ited. It was not working in 1899 and 1000. 
The Sunset, on the southwest slope of Engineer Mountain, is a small 
mine which has shipped a few tons of ore. The lode strikes X. 25° W., 
and dips southwest at an angle of 75 to 80°. It is 1 to 5 feet wide 
and consists of gouge, crushed decomposed rock, and bunches of quartz 
and ore. The country rock is a rather coarsely porphyritic altered 
andesite, like that of the Polar Star. The ore consists chiefly of tet- 
rahedrite and pyrite in a gangue of quartz, with some kaolin. 
The Wewissa is a small mine or prospect on the western spur of 
Engineer Mountain, and is credited wii h a production of about 113,000 
in 1890. It was shipping a galena and tetrahedrite ore, carrying sil- 
ver, in 1899, the ore being taken by burros and wagons to Ouray. The 
lode is irregular and is not extensively worked. 
The Early Bird, on the north slope of Houghton Mountain, is on a 
small and irregular vein striking X. 12° E. and dipping 75° to the 
east. The ore is tetrahedrite and a little galena in a gangue of quartz, 
which is in part a replacement of the andesitic country rock. The 
tetrahedrite carries as much as 300 ounces of silver, and gold up to 7 
ounces per ton is occasionally met with in small amounts. The pros- 
pect has produced 11 carloads of ore ranging in value from $19 to $100 
a ton. East of the Early Bird are two prominent lodes striking 
about northeast, one of which, the Denver, has produced a little ore. 
The London, formerly worked through a shaft near the road, north 
of Houghton Mountain, is now abandoned. It is reported to have 
produced some ore carrying 3 ounces of gold per ton. 
LODES OF HENSON CREEK. 
General. — In the northeast corner of the quadrangle are several old 
locations, some of which have produced ore in considerable quantity, 
but at the present time active work is limited to prospecting on a 
small scale. 
Frank Hough mine. — This mine, situated in American Flats, under 
the northern slope of Engineer Mountain, began work early in 1882 
on large and irregular bodies of argentiferous and auriferous copper 
ore. During 1882 1 he mine was worked through a shaft 250 feet deep, 
with drifts at 50, 80, 140, and 200 feet below the surface. The lower
