English: Plate L from The Geology of the Richmond Basin published by USGS, which has the following caption:
Alluvial plain of the James River, Powhatan County, near Vinita. Looking south. Alluvial land in foreground. Newark terrane in rising ground on the horizon.
The text of the report refers to the figure as follows:

Soils.—As to the soils of this area, it may be said that with the exception of the alluvial plains (see Pl. L), some of which form a fringe along the James River and other considerable streams above the present level of the flood waters, the tillable layer is composed of residual deposits arising from the decay of the Newark beds. Owing to this origin they are sandy clays, or occasionally nearly pure sands. At the best they are of a rather low order of natural fertility, though they would respond quickly to systematic culture with the use of fertilizing materials. The fact that the area underlain by the Newark beds has been less stripped

of its forests than the surrounding country, where the underlying rock is granite or mica-schist, shows that the present methods of agriculture are relatively unprofitable in this field.
