West of Port Henry most of the land is forested but east of it, a lot of hay and field crops such as corn, soy and wheat are grown to feed dairy cattle.

Crown Point jets up into Lake Champlain, where it is crossed by the Crown Point / Champlain Bridge to Vermont.

The French built Fort St. Frederic here between 1734 and 1737 and used it as a base for raids on British settlements in New York and New England. As a result, the British mounted various expeditions to take control of Crown Point, and in 1759 they were finally successful. They immediately began construction of new fortifications that they called "His Majesty's Fort of Crown Point". Enclosing over seven acres this was one of the largest built by the British in North America.

In 1775, at the outbreak of the Revolutionary War, the American colonists captured the fort and secured sorely needed cannons and heavy ordnance. Crown Point was occupied by General John Burgoyne's army in 1777 after the American evacuation to Mount Independence and remained under British control until the end of the war. The ruins of Fort St. Frederic, "His Majesty's Fort of Crown Point," and surrounding lands were acquired by the State of New York in 1910.
