HISTORY OF ORANGE COUNTY
CHAPTER 1


THE CHESTER SANDSTONES

The upper sandstone (No. 5) is very evenly stratified, buff-colored, and is easily quarried by a little stripping in good blocks from one to three feet thick. It makes excellent foundations for barns and residences, where great weight is absent. It weathers well. There are quarries on Locust Hill, and on the lands of Mrs. Clements and Henry Polson. The following is the section at Albert’s Hill, Paoli:

 

FEET

Massive Sandstone. Fossils—leaves and stems of Stigamoria (No. 5)

Blue Shales (No. 5)

Crystalline limestone with Producti, Pentremites, Archimedes, Spirifer, Athyris and stems of Crinoides (No. 6.)

Chester sandstone (No. 7), in many places a shale of no value, is in the vicinity of Paoli an even bedded rock, sometimes thick enough to make good quarry stone. East of town, on the Kibler farm, are quarries of the stone. On J. C. Albert’s land, Section 25, Township 2 north; Range 1 west, is a quarry of tea-green stone, from which blocks of almost any size may be taken. These stones are excellent for flagging. On Lick Creek the lower Chester limestone has been found good for building purposes. It is comparatively soft and friable when taken out, but becomes hard and extremly durable upon long exposure. It was used in the foundation of the court house. It contains inconvenient glass seams. The following is the section at Orangeville:

 

FEET

Massive sandstone stained with iron

45

Middle Chester limestone (No. 6)

Shaly sandstone (No. 7)

The lower Chester is the prevailing limestone at Chambersburg, Valeene and the southeastern parts of the county. It is exposed on the hillsides and in the valleys of Greenfield, Jackson, French Lick, Orangeville and Northwest Townships, and is the only limestone of any economic value in these regions. The following is the section on the road south of French Lick:

 

FEET

Conglomerate. sandstone (No. 3)

45

Upper Chester limestone. with band of chert at top and with Archimedes, Athyris, Pentremites, Spirifer and Producti
