When the water levels were low enough, we could drive up to this area. With the rains this year, it’s since been re-hidden under the waters of this lake.
Other interesting, historical stories from the same area – Similar to the rare-earth minerals at nearby places like Badu & Barringer hill, people claim there’s underwater areas exposed to these same types of rare earth outcroppings & parts of Lake Buchanan are radioactive to the point of being harmful to people. Read these, but especially the 2nd one. This all is so cool and mostly unknown to people around here:
