TINKLER DEPOSIT AT GYPSUM CITY. 
The Tinkler deposit covers an area of twelve acres, and lies 
close to the surface with little or no cover. It lies in the valley 
of a small creek tributary to Gypsum creek. The maximum 
thickness is 17 feet, while the average is 8. The dirt was 
hauled in wagons to the mill, one and one-half miles away. 
The appearance of the deposit resembles very much a fine sand 
bed or loess formation, and there is a tendency to break in 
smooth planes or joints. Organic matter occurs through it, and 
underneath is a layer of clay, and below the clay is a deposit 
known as the black gypsum, regarded as worthless. Strong 
springs break through the deposit on the east side. ‘The top of 
the gypsum earth is 20 feet above the water in Gypsum creek, 
a quarter of a mile to the west. In a well dug om the hill 
above the deposit rock gypsum of good quality was struck 30 
feet down, or 20 feet below the top of the earth. No trace of 
gypsum was found in the hills above the earth deposit.

A number of years after the discovery of the Tinkler gypsum 
area, Mr. Gotlieb Heller discovered a similar deposit fourteen 
miles east, near Dillon station. He purchased the rights to the 
deposit from John Linden for $100 and a team of mules, and 
later it was purchased by the present owners, the Agatite 
Cement Plaster Company. 
This deposit resembles that at Gypsum City. The area is at 
least forty acres in extent, and lies in swampy ground, near a 
small creek. Its greatest thickness is 18 feet. Plate X VIII 
represents the actual working of this deposit. It is covered to 
a slight depth with soil, and water in springs is very trouble- 
some in working this deposit. Gypsum rock outcrops a quarter 
mile away at nearly the same level. This gypsum earth is 
taken out by aid of the plow and scraper, and after drying a 
few days in the sunshine is loaded into cars and hauled to the 
mill, one-half mile north, shown in Plate XIX.
