In 1907, 6 or 7 bandits robbed the Frisco freight train at Mammoth Spring, loading a wagon with several crates. Two trainmen died in the incident. According to witnesses, the bandits headed toward Tick Ridge (or the head of Cold Spring Creek). The loot was placed in a cave and the entrance was dynamited shut until they could return and split it. All the bandits were captured and served long sentences in prison, never to recover the cache. In 1936, a former prison guard began searching for the cache, spending 10 years in a futile effort. He revealed that the train robbers were a gang of burglars that worked Gary and Bloomington, Indiana, Chicago, Illinois, and St. Louis and Springfield, Missouri. The gang had hidden all of their accumulated loot, including jewelry, gold & silver coins and gemstones, in the cave.
