The Patuxent River stone is the state gem (a form of agate) of the U.S. state of Maryland. Since it is found in red and orange this stone could also be referred to as carnelian. [1] It is only found in Maryland and its colors reflect the Maryland State Flag.
The Patuxent River stone became the state gem effective October 1, 2004 through the passage of Chapter 272, Acts of 2004; Code State Government Article, sec. 13-319. [2]
Carnelian is a brownish-red mineral commonly used as a semiprecious stone. Similar to carnelian is sard, which is generally harder and darker; the difference is not rigidly defined, and the two names are often used interchangeably. Both carnelian and sard are varieties of the silica mineral chalcedony colored by impurities of iron oxide. The color can vary greatly, ranging from pale orange to an intense almost-black coloration. Significant localities include Yanacodo (Peru); Ratnapura ; and Thailand. It has been found in Indonesia, Brazil, India, Russia (Siberia), and Germany. In the United States, the official State Gem of Maryland is also a variety of carnelian called Patuxent River stone.

Maryland Route 235 (MD 235) is a state highway in the U.S. state of Maryland. Known as Three Notch Road, the state highway runs 30.63 miles (49.29 km) between its southern intersection with MD 5 in Ridge and its northern intersection with MD 5 near Mechanicsville. While the southern part of the state highway is a two-lane undivided rural road, the northern part of MD 235 is a four- to six-lane divided highway connecting Naval Air Station Patuxent River and the Washington, D.C., metro area in conjunction with MD 5. Three Notch Road has been the main highway between northern St. Mary's County and Point Lookout since the colonial era. The highway was reconstructed as the modern MD 235 between 1923 and 1938. The state highway was then completely rebuilt during World War II to serve the recently established NAS Patuxent River. Between 1960 and 1985, MD 235 was converted into a four-lane divided highway to the west and north of the military base. In the face of increasing activity at the base, the highway adjacent to NAS Patuxent River was expanded to six lanes in the early 2000s.

The Sumerian economy refers to the systems of trade in ancient Mesopotamia. Sumerian city-states relied on trade due to a lack of certain materials, which had to be brought in from other regions. Their trade networks extended to places such as Oman, Arabia, Anatolia, the Indus River Valley, and the Iranian Plateau. Sumerians also bought and sold property, but land tied to the temples could not be traded. There were three types of land—Nigenna, Kurra, and Urulal—and only Urulal land could be traded; Nigenna land belonged to the temple, while Kurra land belonged to the people working in the temple. Within Sumer, the Sumerians could use silver, barley, or cattle as currency
