Vinton County. At some localities in Vinton County the Boggs 

 ore is well represented, although it is generally sparingly fossiliferous. 

 In the black band ore, which outcrops in Spook Hollow in the bed 

 of Elk Creek, one and one-half miles east of McArthur, Lingula 

 carbonaria Shumard is fairly abundant. The section below was 

 measured in Spook Hollow:

Muskingum County. Where the Boggs member is typically 

 developed in Muskingum County, it consists of a limestone associated 

 with or replaced by shale, flint, iron ore, or sandstone. On the land 

 of Delia Wise, Hopewell Township, flint and iron ore mark the horizon. 2 

 The limestone phase is shown on the land of Delard Fink, Section 18 

 of the same township, where the following section was measured, 

 but no collections were made. 3
