Question

1st page only. For question D.5) how deep is the well?

Answer 1

It appears that the dark blue edge of the pond on Bald Knob is at an elevation of about 825 feet. The level of water in the sinkholes to the southeast of Bald Knob is at 540 feet. So, the well has to be at least 285 feet deep (825 - 540 = 285).
