The Dutch first settled Delaware. The Swedish then took over in the mid-1600s.



Delaware is 96 miles (154 km) long and ranges from 9 miles (14 km) to 35 miles (56 km) across, totaling 1,954 square miles (5,060 km2), making it the second-smallest state in the United States after Rhode Island. Delaware is bounded to the north by Pennsylvania; to the east by the Delaware River, Delaware Bay, New Jersey and the Atlantic Ocean; and to the west and south by Maryland.



Delaware is on a flat plain, with the lowest mean elevation of any state in the nation.[13] Its highest elevation, located at Ebright Azimuth, near Concord High School, is less than 450 feet (140 m) above sea level.[13]



The transitional climate of Delaware supports a wide variety of vegetation. In the northern third of the state are found Northeastern coastal forests and mixed Oak forests typical of the northeastern United States.[14] In the southern two-thirds of the state are found Middle Atlantic coastal forests.[14] Trap Pond State Park, along with areas in other parts of Sussex County, for example, support the northernmost stands of bald cypress trees in North America.

Environmental management


Delaware provides government subsidy support for the clean-up of property "lightly contaminated" by hazardous waste. The money for this cleanup comes from a tax on wholesale petroleum sales.[15]

Sister cities and states


Delaware's sister state in Japan is Miyagi Prefecture.[16]
