Before the invention of electric refrigerators, blocks of ice in insulated wooden cabinets called “iceboxes” kept food from spoiling quickly in warm climates. This required access to ice, which had to be hauled in from cold climates by boat, and wasn’t always available, especially in remote places. The picture above shows a cool water spring that was modified long ago into a primitive kind of refrigerator. The structure is made of concrete. When it was in use, it would have had a door to keep cool in and keep animals and insects out, as much as possible.
Just like caves, cool water springs in Arkansas stay close to 56 degrees in the summer – the ambient ground temperature. Anyone that’s spent a summer in Arkansas knows it gets oppressively hot. Having a place you could store milk, eggs, and other perishables would certainly have come in handy. You still come across these old structures if you spend a lot of time out in the woods around the state. This one was photographed near Hot Springs, Arkansas, in the Ouachita Mountains.
