Colorado and was abandoned about August 20, L889, by reason of 

 accidental flooding, supposedly from the Loveland mine to the north. 1 



A longitudinal cross-section of the < 'Id White Ash mine at the date of 

 abandonment is given in C, PI. XVIII. The collar of the shaft is 135 feet 

 west (if the main worked seam, and at the 600-foot level is still 39 feet to 

 the west. Below this the strata become vertical, with indications of an 

 easterly turn, so that the shaft will nowhere cut the main seam. The seam 

 is opened from the shaft by cross-cuts, levels being driven from these. A 

 second seam. .". feet thick, lies from 1<) to 20 feet west of that worked. This 

 has been found to vary considerably in thickness, but has never fallen 

 below workable limits. 



The floor and roof of the large seam is either a black or gray slate or 

 clay, or a gray sandstone, the former more commonly occurring. The 

 entire seam is generally free from partings, and the coal from below the 

 200-foot level is extremely hard ami bright. 



The Lovciand mine. — This is just north of Clear Creek, on the same seam 

 as the Old White Ash. The width of the seam is reported between 9 ami 

 1.0 feet, with occasional partings. The coal ranks with that of the Old 

 White Ash. The smaller seam, wot of that worked in the Old White Ash 

 mine, again appears here with a thickness of 4 feet. 



The New White Ash mine. (Fig. < ), PI. XX.) This Ulille, opened ill 1890, IS 



located about a half mile north of Clear Creek. There are two workable 



seams, 32 feet apart, having in the portion opened a X. 7 : W. strike, and a 



dip of 75° to so west (overturned). The strike gradually changes to 



north as distance in this direction is gained, while the dip slowly approaches 



the vertical in depth. The west seam is ,'! feet 6 inches to 4 feet wide: the 



east 4 feet, but indicating an increase below present levels. Both seams 



are worked from the same shaft, which, in October, 1800, had reached a 



depth of 317 feet, with cross-cuts to the beds at 1 7:;. 2 b'., and , - !17 feet. 



"'Recently a fatal accident occurred, causing the death of ten men who were working at the 

 end of the lowest level of the White Ash mine in the direction of the Loveland mine. The latter 

 mine has for years heen full of water. Oneof the upper levels of the Whit.' Ash, which if protracted 

 would have made connection with the lowest level of the Loveland, has for a long time been on fire, 

 and it is supposed that this at last burned through into the Loveland, letting in the water, which ran 

 down the White Ash shaft aud drowned the men working in the levels below. The bodies of the 

 men have not been recovered, aud the mine has been closed down since the accident." (Ann. Report 

 Golden School of Mines fur 1889, p. 60.)
