Not to bring the dead back to life, but I recently found an interesting thing.
As everyone now knows there are a series of caves near Henley on the Osage River, at least one of which still retains the name Crabtree Cave. Any of those could have been used but I suspect a different cave rather than the eponymous one - its entrance is very difficult to get to and that makes for a poor hideout (no horse, one way out). A much better cave is nearby and has at least two routes into it.
Also there was described in these stories a local man named Bax and there is still a Bax Cave not far away on Tavern Creek, one of several in that area.
The interesting thing is that there is another Crabtree Cave in Missouri. This one is located in southern Crawford County on Huzzah River. During the Civil War that river was still known by its original name: Osage. Huzzah is a derivative of the French pronunciation of Osage, which is why that part of Crawford County is still in Osage Township.
Maybe Crabtree had an affinity for caves along rivers named Osage:)
