Spinal Springs

Spinal Springs is an alignment of depressions (intermittent springs) in the central part of the Racetrack playa. It is 550 m long and starts, at its northern end, with conical depressions only a few centimeters deep. Traced southward the depressions increase to ~5 m in width with scattered creosote shrubs. They then narrow and become shallower again, and finally disappear. Further north and south along this linear formation, there were several other depressions that may be a continuation of the Spinal Springs alignment.^[1]
