Blueberry Spring is a fifth-magnitude spring that discharges from a small sand boil in the hillside. The circular pool is about 5 feet in diameter, with organic debris and white sulfur-reducing bacteria covering the pool bottom. Several more sand boils are present in the run further down the hillside. The spring runs toward the east to Black Water Creek.
