Beyond Woolsey, a siding and section house, the npper beaches of 

 Lake Lahontan are very distinct, especially in evening light. The 

 raih'oad now begins to descend to the broadening bottom lands of 

 Lovelock Valley, with its trees, fields, and ranch buildings. 



Kodak is a sidetrack from which gypsum was formerly shipped 

 to a plaster mill at Reno, and fragments of the gypsum rock are

strewn along the raili-oad. They are of granular 



texture, like loaf 



sugar, 



and some portions show 



distinct lamination or banding. The deposit is an 

 immense mass that forms a bare bluff of light-colored 

 material in the low slopes of the Humboldt Lake Range opposite 

 Kodak. It is evidently an interbedded layer in the Triassic sedi- 

 mentary series, probably a chemical . deposit formed in Triassic time 

 in a comparatively small basin. Deposits of gypsum were laid down 

 over very extensive areas during Triassic and Permian time in other 

 parts of the country, indicating widespread conditions of aridity in 

 those periods. 



Lovelock and the adjacent Lovelock VaUey, the lower 16 or IS 

 miles of the valley occupied by Humboldt River above Humboldt 



Lake, constitute one of the most prosperous agri- 

 cultural settlements of Nevada. Lovelock is also 

 the railroad and supply point for a number of mining 

 districts. At present its principal industries are 

 connected with the raising of sheep and cattle and 

 especially the winter feeding of stock. The river is 15 to 25 feet 

 below the general level of the cultivated flood plain, so that it is 

 necessary to bring the water for irrigation in ditches from points 

 upstream. In 1900 about 14,000 acres were nrigated, and a little 

 over half of this area was in alfalfa. ^ATieat, barley, and potatoes 

 are also grown, and the town has a flour miU. 



Of the mining camps which are generally reached by way of Love- 

 lock, Seven Troughs,^ a gold camp, is at present the most important. 

 North of Lovelock, in the Trinity Mountahis, is the Montezuma 

 mine, which, supplied antimonial lead-silver ore to the Oreana smelter 

 in the sixties. There are a number of antimony deposits in the 



Tertiary volcanic rocks and occur in 

 veins of soft, crushed material wluch 

 does not crop out at the surface. The

^ The Seven Troughs district, including 

 four little to\vns, Seven Troughs, Vernon, 

 Mazuma, and Farrell, is about 30 miles 

 northwest of Lovelock and lies on the 

 east slope of a minor range now generally 

 known as the Seven Troughs Mountains.
