"This river is hidden," said a French adventurer credited with naming the Cache when he spotted its log-jammed mouth on the Ohio in 1702. His words are still true today as the natural features, the hidden treasures of the Cache, these remnants of its past, must be actively sought out to be experienced. The word cache comes from the French and means "something hidden, or stored." In Illinois, our Cache is a treasure trove of biological wonders and a wetland of international significance. The Cache River Basin crosses Southern Illinois, from the Ohio River on the east to the Mississippi River on the west, and is the prehistoric river valley of the Ohio. Referred to in the original United States Land Survey as "inaccessible and a drowned land," the basin marks the geographical point where the last invasion of the sea into the Midwest reached its northernmost limit, and lies only a few miles from the southernmost extent of the continental glaciers. The Cache Basin supports a diverse mixture of forests, grasslands, wetlands, shallow lakes and streams and is the northern limit for cypress-tupelo swamps in the Mississippi Valley.
