GEOLOGICAL SETTING
Late Pleistocene sediments in Meade County have occasionally been referred to formations named for sediments of this approximate age in Clark County (e.g., Kingsdown, Vanhem;
Hibbard and Taylor 1960), but we doubt this nomenclature can be extended to Meade County and currently view such accumulations as localized basin-fill deposits (Martin et al. 2000). The Golliher quarries are located along about 20 m of a partly exposed bank on the north side of Sand Creek, Meade County, on the property of Dave and Kathy Golliher.
Measured section along Sand Creek at Golliher quarries in NW NE SW, Sec. 3, T. 33 S, R. 27 W, Meade County, Kansas. Measured by J. Honey, P. Peláez-Campomanes and R. Martin.
