About Blanchard Springs:

Rainwater falling on the Ozarks has soaked into the ground for millions of years. As it moved through cracks in the limestone bedrock, it dissolved the stone and slowly widened the cracks to form Blanchard Springs Caverns.The water remained in the caverns until surface erosion carved valleys and allowed the water to escape. You are in such a valley now. As this valley cut deeper and deeper, lower sections of the cave were drained. New springs then developed below older dried-up springs. Blanchard Springs probably came out of the holes high on the bluff above us many years ago, when the streambed lay 20 to 30 feet above its present level.
This stream flows through bat sanctuaries on its way through Blanchard Springs Caverns. The water is enriched because of bat wastes and the decaying remains of those that died. Although this does not affect the appearance of the water, it does make it unsafe to drink.
