Whitehall is a colonial home that was built beginning in 1764 near Annapolis in Anne Arundel County in the Province of Maryland by Horatio Sharpe, then the provincial governor of the British colony of Maryland. The house is located about 7.5 miles (12.1 km) to the east of Annapolis on a peninsula between Whitehall Creek and Meredith Creek, opposite Sharpe's Point on a branch of Chesapeake Bay. The site, originally comprised about 1,000 acres (400 ha). The house is a five-part Georgian mansion of great length, only one room deep in the main section. It features elaborate original interior woodwork, attributed to William Buckland, and is one of only two pre-Revolutionary houses in the Thirteen Colonies to have a temple portico. It was designated a National Historic Landmark in 1960.

NSS Annapolis
NSS Annapolis

NSS Annapolis, officially known as Naval Communications Station Washington, D.C. Transmitter or NavCommStaWashingtonDC(T), was a Very Low Frequency (VLF) and High Frequency (HF) transmitter station operated by the United States Navy. It was located at Greenbury Point, in Anne Arundel County, across the Severn River from Annapolis, Maryland at coordinates 38°58′40″N 76°27′12″W. NSS Annapolis was used by the USN for submarine communication. The station consisted of an umbrella antenna supported by a 1,200-foot (365.76 m) high central mast, which was insulated against ground, 6 guyed masts of 800-foot (243.84 m) all of which were built in 1969 and three 600-foot freestanding towers built earlier. Originally the station consisted of nine 600-foot-tall self-supporting lattice towers, the tallest of their kind built in the United States to that date. The first four of which were built in 1918, followed by two more in 1922 and the final three in 1938. As of 2020, only the three built in 1938 remaining standing. The huge towers were a local landmark, and served as a visual reporting point for aircraft landing at the nearby Baltimore-Washington International (BWI) airport. A golf course runs through the former HF antenna farm; special rules addressed hitting a tower with a ball (usually stroke and distance). The NSS HF receiver station, and the headquarters for NavCommStaWashingtonDC(T), was located at the Naval Communications Station in Cheltenham, Maryland until 1969. In late 1969, the receiver station at Cheltenham closed and a new receiving station was activated at Sugar Grove, West Virginia. NSS began transmitting in September 1918 using a pair of Federal Electric 500 kilowatt Poulson Arc transmitters. However, arc transmitters were significantly inferior to the then state-of-the-art Alexanderson alternator and one of the arc transmitters was replaced by a more modern TAW 300 kilowatt vacuum tube transmitter in 1931. VLF, or "longwave" radio was the standard at the time for long-range radio transmission, only to be replaced by shortwave in the early 1930s. VLF later became essential for communicating with submerged submarines, a critically important capability as submarines became strategic missile platforms. The NSS transmitter fed one million watts of radio energy to its antenna, and during idle times, transmitted the string "W W W VVV VVV VVV DE NSS NSS NSS" in Morse code. The power was so high and the frequency so low, one could hear the signal on practically any kind of receiver anywhere in the Annapolis area. Messages were also sent in Morse code, but were either prearranged code signals or were encrypted. Rendered obsolete by satellite technology and the end of the cold war, NSS ceased operation and all of the antennas and most of the towers were demolished in 1999. Three of the smaller 600-foot towers were preserved near the tip of Greenbury Point to serve as aids to navigation for boaters on the Chesapeake Bay. The callsign, operating from Annapolis, was brought back for the May 8, 2021 Armed Forces Day radio test. This is an annual event when amateur radio operators can work through crossband communications with certain military stations. However the station was active for only 16 hours.

Little Magothy River

The Little Magothy River runs 2.5 miles (4.0 km) through Anne Arundel County in the U.S. state of Maryland. It is located southeast of the Magothy River, just outside its mouth and north of the Severn River. A small, mostly tidal river, the Little Magothy's watershed (not including the water surface) covers an area of 2.2 square miles (5.7 km2). All mailing addresses in the watershed are in the Annapolis zip code, and the entire watershed is within Anne Arundel County, on the north side of the Broadneck Peninsula. It is bordered on the west by the community of Cape Saint Claire, and on the east by houses and farms along Bay Head Road. It runs just west of Sandy Point State Park. It starts near College Parkway and US 50/301, just north of the Whitehall Creek watershed (which is part of the Severn River watershed that drains to Whitehall Bay), and it flows north into the Chesapeake Bay south of Gibson Island. It has one named nontidal creek that drains into its upper end, Cat Branch, which flows under Cape Saint Claire Road. According to "My River Speaks," p. 141, Cat Branch was dammed in the mid-18th century to supply water through a canal to a mill in the upper Whitehall Creek watershed (part of the Severn River watershed). The 6.5 miles of Chesapeake shoreline including the Little Magothy River and stretching to Sandy Point, all well beyond the official mouth of the Magothy (which is 325 meters south of the southern tip of Gibson Island) are not in the Magothy drainage basin but are often included in county and state government studies of the Magothy watershed.

Sandy Point Shoal Light
Sandy Point Shoal Light

Sandy Point Shoal Light is a brick three story lighthouse on a caisson foundation that was erected in 1883. It lies about 0.6 mi (0.97 km) off Sandy Point, north of the Chesapeake Bay Bridge, from whose westbound span it is readily visible.The current light replaced a brick tower on the point itself, integral to the keeper's house, which was erected in 1857. By 1874 the Lighthouse Board complained that the extent of the shoal and the poor equipment of the lighthouse made a new light necessary; appropriations were not forthcoming, however, until 1882. The whole gamut of light sources has been run, from oil wicks to incandescent oil vapor (1913) to electricity (1929). The characteristic changed from flashing to fixed and back to flashing along with the change in light source. The present light is powered by a pair of solar panels attached to the roof on the south side.After automation in 1963, the light became subject to vandalism due to its visibility and its accessibility. The original lens was destroyed in 1979, apparently smashed with a baseball bat. Though the Coast Guard made efforts at maintaining and restoring the structure from 1988 to 1990, it continued to deteriorate. In 2006 it was sold at auction to a private bidder, after an unsuccessful attempt to find a non-profit group to take responsibility for the light. The Coast Guard continued to maintain the navigation aids until June 2019, when the light was discontinued due to deterioration of the privately owned supporting structure. The structure was added to the National Register of Historic Places as Sandy Point Shoal Light Station on December 2, 2002.
