Charlie McClendon runs the music ministry at Goodwill Baptist Church in Hampton. McClendon was integral in ending music segregation in the Tidewater region with his group Charlie McClendon and the Magnificents in the 1960s. McClendon photographed on on Sunday Dec. 2, 2012. (Photo by Pat Jarrett)
Showing segregation of facility between pedestrian and cyclists (and rollerbladers!). The bike section is also painted green round here.
Found this unreal but original print from 1930 on ebay - had to buy and preserve it, because it is such a straightfful composed iconographic image for racial segregation.

Eroded and exposed areas of this Tifton soil have a significant amount of both hardened plinthite nodules and ironstone nodules. Once exposed, over time the reddish redox concentrations in the subsoil hardened to form plinthite. The plinthite nodules once hardened to the point of being strongly or more cemented, become ironstone nodules.
From a genetic viewpoint, plinthite forms by segregation of iron. In many places iron probably has been added from other horizons or from the higher adjacent soils. Generally, plinthite forms in a horizon that is saturated with water for some time during the year. Initially, iron is normally segregated in the form of soft, more or less clayey, red or dark red redox concentrations. These concentrations are not considered plinthite unless there has been enough segregation of iron to permit their irreversible hardening on exposure to repeated wetting and drying.
The identification of plinthite in the field is somewhat subjective because an exact definition including measurable properties has not been adopted. Therefore, no “required characteristics” are provided. (Keys to Soil Taxonomy, 2022)
The following discussion provides general guidance for identifying plinthite. Plinthite is firm or very firm (and is commonly brittle) when the soil moisture content is near field capacity and hard when the moisture content is below the wilting point. Plinthite occurs as discrete bodies larger than 2 mm that can be separated from the matrix. A moist aggregate of plinthite will withstand moderate rolling between thumb and forefinger and is less than strongly cemented. Moist or air-dried plinthite will not slake when submerged in water, even with gentle agitation. Plinthite does not harden irreversibly as a result of a single cycle of drying and rewetting. After a single drying, it will remoisten and then can be dispersed in large part if it is shaken in water with a dispersing agent.
In a moist soil, plinthite is soft enough to be cut with a spade. After irreversible hardening, it is no longer considered plinthite but becomes ironstone (if strongly or more cemented). Indurated ironstone materials can be broken or shattered with a spade but cannot be dispersed if they are shaken in water with a dispersing agent.
A small amount of plinthite in the soil does not form a continuous phase; that is, the individual redox concentrations or aggregates are not connected with each other. If a large amount of plinthite is present, it may form a continuous phase. Individual aggregates of plinthite in a continuous phase are interconnected, and the spacing of cracks or zones that roots can enter is 10 cm or more.
If a continuous layer is indurated, it becomes a massive ironstone layer that has (may have) irregular, somewhat tubular inclusions of yellowish, grayish, or white clayey material. If the layer is exposed, these inclusions may be washed out, leaving an ironstone that has many coarse tubular pores.

__________________________________
This soil was correlated as the Tifton soil series. The Tifton series was one of the first series to be recognized in Georgia. It was established in Grady County, Georgia, in a 1908 soil survey conducted by Hugh Hammond Bennett. Tifton soils occur throughout the Southern Coastal Plain in Georgia.
They are the most extensive soils in Georgia. They occur on more than 2 million acres in the State. They have been correlated in more Georgia counties (56) than any other soil. Tifton soils formed in loamy sediments of marine origin. They are among the most important agricultural soils in the State. About 27 percent of Georgia’s prime farmland is in areas of Tifton soils. Cotton, peanuts, soybeans, and corn are the principal crops grown on these soils.
The Tifton series consists of very deep, well drained soils that formed in loamy marine sediments. Tifton soils are on interfluves. Slopes range from 0 to 8 percent. The surface and subsurface horizons contain 5 to 25 percent ironstone nodules. The subsoil contains 5 to 30 percent or more nodular plinthite and 0 to 15 percent ironstone nodules.
TAXONOMIC CLASS: Fine-loamy, kaolinitic, thermic Plinthic Kandiudults
USE AND VEGETATION:
Most areas of Tifton soils are under cultivation with cotton, corn, peanuts, vegetable crops, and small grains. Some areas are in pasture and forestland. The forested areas consist largely of longleaf pine, loblolly pine, slash pine with some scattered hardwoods on cutover areas.
DISTRIBUTION AND EXTENT:
Major Land Resource Area (MLRA): The series occurs primarily in the Southern Coastal Plain (MLRA 133A), but it also occurs to a lesser extent in the Atlantic Coast Flatwoods (MLRA 153A).
Extent: large extent

This image shows a set of beads of two different diameters in a large scale annular rheometer. The sample is sheared from above by a rotating rotor. Using a laser sheet, we capture the granular segregation that appears between the beads.
