ELKTON is situated at the head of Elk River on the Talbot terrace, which is underlain at this point by Potomac clays (Lower Cretaceous). Surrounding the town on the north, east, and west are the higher and older terrace formations (Wicomico and Sunderland). Farther to the northward is an extensive area of granite-gneiss overlain along the eastern margin by Cretaceous sediments. The very characteristic hypersthene gabbro outcrops at Grays Hill and along the valley of Big Elk Creek. Farther to the north and west in Cecil County occur serpentine and other eruptive rocks, while to the south along Elk Neck and in southern Cecil County may be found an extensive series of Upper Cretaceous and Tertiary formations, many of them rich in marine organic remains.

CHESTERTOWN is located on the Talbot terrace in the valley of Chester River, although the escarpment of the Wicomico terrace is found on the northern margin of the town. This older terrace covers an extensive area in central and eastern Kent County. Eocene deposits, either unaltered greensands or oxidized reddish sands, are found beneath the terrace cover. CENTERVILLE likewise lies near the margin between the Talbot and Wicomico terraces, the latter covering an extensive area to the south and east of the town. Beneath these surface formations both at Centerville and throughout most of Queen Anne's County occur Miocene formations, which at a few points have furnished marine organic remains.

EASTON is likewise situated near the margin between the lower Talbot terrace and the next higher Wicomico terrace, the latter covering an extensive area in central and northern Talbot County. Beneath these formations the Miocene marine beds are found, as is the case farther north.

DENTON is situated in the valley of the Choptank River along the basin of which the Talbot terrace extends from Chesapeake Bay as far as Greenville. To the east and south of Denton the higher Wicomico terrace spreads out as a broad plain throughout the central, southern, and eastern portions of the county. Beneath this surface formation Miocene strata are found with their marine fossils.

SOUTHERN EASTERN SHORE

This division of the state is wholly within the area of the Coastal Plain and presents many features in common with the southern part of the district just described. It is very low, rising only at a few points to 80 feet in height above tide, this elevation being reached in the remnants of the Wicomico terrace, which extends southward only at a few points into the southern Eastern Shore. Most of the district is covered by the Talbot terrace, which around its landward margin does not exceed 40 feet in elevation, although a large part of the area in the southern counties is below 25 feet in elevation above tide. The underlying formation of Miocene age only outcrops at a few points in the northern part of the district, although deep-well borings have penetrated these and still older formations. Marsh lands cover extensive areas in Dorchester, Wicomico, and Somerset counties, while the Atlantic border of Worcester County has a splendidly developed ocean sand bar nearly inclosing a large area of brackish water known as Chincoteague Bay.

CAMBRIDGE is located on the Talbot terrace, which spreads as a leveltopped plain of many hundred square miles in area in all directions, reaching far into the confines of adjacent counties. The Wicomico terrace appears some miles to the eastward at East Newmarket, but covers only a small area in eastern Dorchester County. Underlying the deposits of these terraces are the later formations of the Miocene, which outcrop at a few points near Cambridge and farther up the Choptank River where characteristic marine fossils have been found.

SALISBURY is situated on the Wicomico River on the Talbot terrace, although the Wicomico terrace appears not far to the north and east, but from its seaward slope it is much lower here than in the counties farther northward and the escarpment separating the two terraces is less sharply defined. No deposits of older date are found along the stream channels, although well borings have penetrated the underlying Miocene formations.

PRINCESS ANNE is located on the Talbot terrace but a few feet above tide level, the terrace here being broad and level and reaching well to the northern limits of the county, where at one point in the northeastern

corner the Wicomico terrace projects itself for a short distance beyond the boundary. No underlying deposits are found along the stream channels, although they have been penetrated in well borings, especially at Crisfield, where a well boring over 1000 feet in depth has not only penetrated the Miocene deposits but also the Eocene and Cretaceous as well, although it has not touched bed rock.

SNOW HILL is likewise found on the Talbot terrace very near tide level, the terrace plain here likewise stretching in all directions for many miles. The Wicomico terrace is only found in a few detached areas near the north and northwest borders of the county. The Talbot terrace contains along its seaward margin various later deposits of wind-blown sand that at times reach the proportions of important dunes, while the bars and spits along the coast possess much of recent geologic interest. No underlying deposits are found, although deep-well borings in adjacent areas show that these formations exist at depths beneath the surface cover of terrace formations.
