Did you know from 1959 thru 1970 Mud Island was a one runway airport?? Mud Island as we know it today opened in 1982. The River Museum was closed this summer as they plan for the next phase of the park’s history, but the scaled replica of The Mississippi River is still rolling right along!! If you have never seen this model, you need to go! This hydrologic model shows the river from Cairo Missouri and empties into one acre ”Gulf of Mexico ” that holds a whopping 1.3 million gallons of water(Bud Boogie Beach to old-time Memphians😊). Plus, as an added bonus, has some of the best views of the city’s skyline..one might say a bird’s eye view 😊
