Measured Sections

The following measured sections are arranged by geographic location. The color terminology used in the descriptions was determined with the aid of the Rock-Color Chart (Geological Society of America, 1951), which uses the Munsell system of dividing all colors into three basic components: hue, value, and chroma. The symbol (5Y7/2), for example, indicates a color in the middle of the yellow range of high value (almost white) and low chroma (pale, approaching gray). The corresponding name of this symbol is yellowish-gray. Shades of gray are indicated by the symbol N followed by the value. Additional measured sections for the county are available for examination in the open files of the State Geological Survey of Kansas and the Ground-Water Branch, U.S. Geological Survey, in Lawrence, Kansas.
