Final answer:
The Great Salt Pond is located in Jordan, a salt lake known for its high salinity and unique ecosystem.
Step-by-step explanation:
The country that has the Great Salt Pond is Jordan. It is a salt lake located in the Jordan Valley, bordered by Jordan to the east and Israel and Palestine to the west. The lake is known for being one of the world's saltiest bodies of water, providing a unique ecosystem for salt-loving organisms to thrive in it.
The high salinity of the water is caused by evaporation and the presence of halophilic microorganisms like Dunaliella algae and Halobacterium.
