Also known as Ozark Terminal, the underground limestone mines north of the town of Neosho began in 1943, and warehouse construction there began in 1956. There are two principal portal areas. One is the main Ozark Terminal, which has three portals leading to leased spaces underground. The other is dominated by the JT Sports Licensing Company, which has a few brands of sports equipment products, mostly baseball-related, such as Rawlins bats and gloves, which are warehoused inside. Total square footage inside is around 2 million square feet, 600,000 of which is developed into nine rooms.
