Out of your area but..... My Grandad told me a story. Around 1900 an "eastern" magazine had a story about stolen gold from a military shipment near Calhoun,MO. Henry Co. He said people would just show up & start roaming the "100' Bluffs" south of Calhoun on Tebo creek. Locals kind of got a kick out of it. I have never heard this story from any of the local historians.
What I can say is a friend of mine found a stone arrowhead in a dead tree in that area. I surveyed the Gvt. Boundry on Truman Lake. Just south of Calhoun is the Northern most point of the lake. The first 1/2 mile of boundary lies in the middle of Tebo Creek. To find the middle of the creek I had to let myself down the bluffs there on a rope to hold a prizim on the face of the bluff to get the distance across the creek. The next 1/2 mile has both banks and the third 1/2 mile also lies in the middle of the creek. The owners of the Right Bank took an easement.
This is rough country and during the first World War a moonshiner had a Gvt. man trying to find his operation. Locals would find the Gvt. Man hiding in the woods. He was never successful .
Anyway, theres the tale and the general location. Mayhaps you can find out more of the story. I do have to tell you. I worked in that area for several months and every time I was around the bluffs I felt as if someone were watching me. KGC?
