Bay

In physical geography, a bay or gulf is a collection of water (either a lake or sea) that is surrounded by land on three sides, and open to more water on the fourth. In a way, this makes it the inverse of a peninsula.

Some well-known bays are:

• Persian Gulf between Saudi Arabia, Kuwait, Iraq, and Iran
• Bay of Biscay in France
• Bay of Pigs on Cuba
• Gulf of Bothnia between Sweden and Finland
• Gulf of Finland between Finland and Estonia
• Mexican Gulf between Mexico and the United States
• Riddarfjärden in Stockholm
• San Francisco Bay

Bay is a color of the hair coats of horses, characterized by a body color of dark red (known as blood bay) to deep brown, with black mane, tail and lower legs. Some bay horses may have darker coloration in bars on their shoulders and rarely, a dark stripe down the back. The hair coats and hides of bay horses are noted for their durability and sun resistance. For this, among other reasons, bay is a favorite color among ranchers and horse enthusiasts.
