There are a number of references to gold being found in "western Kansas" in the area of Cherry Creek. These appear to refer to the Kansas Territory, and Cherry Creek is now Colorado, near Denver. Rumors in 1896 said that gold was found in Hollenberg. However, gold is where you find it. There have been diamonds found in Indiana, carried there by glaciers, so there might be some gold in Kansas that has been carried there by some ancient river. It is unlikely. Good luck and have fun.
