$ 75,000. 
At the Clinton Claim, in Grizzly Cafion, an area of 600 feet by 100 was sluiced off to a depth

At Weske’s Mine, near Michigan Bluff, June 16, 1871, Mr. Goodyear saw washed out from 
eight car-loads of gravel, of about fourteen cubic feet each, the result of one day’s work, with 
twenty men employed, 914 ounces of gold, worth $1,601.25. The total yield for the current 
week, at this claim, was 5143 ounces, worth $8,939.44. At this claim the distance worked on 
the channel in five months was about 200 feet, and the yield during the first five days of the week 
of Mr. Goodyear’s visit was 352 ounces. Weske’s Mine had yielded something over $ 100,000 up

Fabulous stories are told of the richness of Dutch Gulch, which lies between the point of the

repeatedly made, was to the effect that in drifting here two men took out 1,200 ounces in one 
week ; this was at the Empire Claim. Stickner’s Gulch, which runs down on the opposite side of 
the point at Michigan Bluff into Skunk Gulch, is also said to have been extremely rich, although 
not comparable with Dutch Gulch. 
At Ayer’s Claim, on the east side of the ridge facing El Dorado Caiion, north of Michigan Bluff 
from a space, near the mouth of the tunnel, about a hundred feet long and from thirty to forty 
wide, about $ 30,000 was taken out, and after that nothing farther was found.
