This handsome stack reaches on beside the road for acres. Because it is on the down slope of the hill, the waller has left little Weep Holes to prevent the wall collapse, in case too much water drains down the hill too quickly. Central Texas is known for its’ gully washers and a spring storm that deliverers 2-3 inches in a 30 minutes can easily compromise even the sturdiest of stacks. As we drove along, little patches of blue blinked at us through the hillside.
