(6) The next section is obtained from Lancaster, Fairfield county. A well drilled here in 1886, gives the following record, viz.: The Berea shale is not named in the driller's record, but it is, without doubt, included in the 268 feet described as soapstone, as it is present in characteristic form in all the outcrops of its proper horizon throughout this portion of the state. The interval from the Berea grit to the limestone, is 630 feet. The surface of the Berea grit is here about 450 feet above tide. It is higher than in the last sections, because the outcrop of the formation is bearing to the west of south at this point. (7) In Hocking county wells have been drilled at various times and at various places within the last few years, all of which show the series to be entirely regular here. The record of a well drilled at Logan in 1885, is as follows: The Berea grit is here about 100 feet above tide. At Bloomingville, on the western side of the same county, a num ber of wells have been drilled. The record of one is as follows: Light-colored shales, interstratified with sandstone courses (Cuyahoga shale)....... 445 feet. The same series is shown in Vinton county, but no detailed record of drilling done there is at hand. The Cuyahoga shale, Berea shale, Berea grit, and Bedford shale, all in their characteristic phases, are as unmistakable here as in the records already reviewed. (8) A well drilled at Jackson Court-house in Jackson county, in 1886, found the Berea grit at 700 feet below the surface. The series here was normal in every respect. (9) This line of sections is terminated at Ironton, Lawrence county, in the Ohio Valley. A deep well drilled here in 1885, furnished interesting and valuable information as to the order of the underlying rocks, and the record is entirely in keeping with what we have already obtained in the district to the north. The record is as follows: Lower coal measures (Conglomerate group)........... Elevation of the surface of the Berea grit below tide, about......... 460 B. A second series of sections taken along the line marked "B" on the map, can be followed southward from Cleveland to Marietta. The Berea grit is exposed in the walls of the Cuyahoga Valley at Bedford and Independence in its most characteristic and valuable form. Sections embracing the Cuyahoga shale, the Berea shale, the Berea grit, the Bedford shale, and the upper portion of the Ohio shale, are available at many points. At Independence, the Berea grit lies quite high in the hills, but it has descended to the level of the valley at Peninsula. The interval between the Berea grit and the underlying limestone in this region is about 1,400 feet, as is shown by the Cleveland Rolling-Mill well and other deep drillings. The sandstone has an elevation of about 800 feet above tide in its most northern exposure. (1) At Akron, the Berea grit is found at a depth of 260 feet below the surface, and at an elevation of about 940 feet above tide. It is carried upward here by the water-shed axis, as previously noted (page 58). The section in the deep well drilled here in 1885, is as follows: The black Berea shale is not reported here. It is sometimes missing in this particular portion of the state. The Bedford is not reported as a red shale at this point, but the section is not at all ambiguous. In a number of wells drilled in this general region the facts appear in normal order. (2) The second station is found at Massillon. Several deep wells have been drilled here within the last year. The section from one of them is as follows: The surface of the Berea grit is about 325 feet above tide at this point. (3) The next section on line B is found at Canal Dover, where a deep well was drilled in 1884. A more careful record was preserved of this well than of any other in this portion of the state. The Berea grit was found with a thickness of twenty-six feet at the depth of 860 feet below the surface and at an elevation of eighty-four feet above the sea. The section is as follows: The drill was sunk 1,884 feet below the Berea grit through a constantly changing series of blue, gray and black shales. Drilling was arrested at a depth of 2,760 feet without having reached the bottom of the shale series, but it is probable that the lower limit of the shale series is not far below. (4) Cambridge, Guernsey county, furnishes the next section. The Berea grit was found here in two wells drilled in 1886 in an unequivocal section. The record of well No. 1, is as follows: White sand (Macksburg sand or Berea grit) with oil-gas and salt |
