Limestone vein in creek bed.

Limestone vein ["shelf" or "bench"] in bed of Little Manatawny Creek east [downstream] from the DeTurk House. This bedrock layer ["shelf"] forms the natural bedrock "footings"{1} bearing the foundation walls of the house, which has been more accurately described as an "ancillary," multi-purpose structure, acknowledging its affiliation with the original (expanded) DeTurk farm houses and with other subsidiary buildings ("dependencies") of the early farmstead. This limestone bed is part of the wide stratum extending from Yellow House northward to Lobachsville, and is related to the east-west belt from Boyertown through Greshville to Yellow House.{2} FOOTNOTE: {1} SEE DTR09PH69--1001.01.153 [first two paragraphs in Description, and footnote {1} to the first paragraph]. {2} A quarry in Maxatawny Township, Berks County, located north of Rte 222 and west of Long Lane produces similar white-veined blue dolomitic limestone.
