We spent a few days in the Okavango Delta, a marshy river filled with reeds and water lilies. We traveled to our bush camp in a mokoro, a canoe carved out of a tree trunk, poled by a local guide. The first night we stayed on Makoba Island, named for the local word for the acacia tree that is prominent on the island. The islands in the delta are formed from termite mounds that coalesce into a large land base. The termite mounds are also used as direction guides since they always lean toward the west.
