68 THE DEEP DIVE

CHAPTER 68 THE DEEP DIVE Our robot swam down down down into the deep, dark ocean. She brightened her headlights and noticed that debris was scattered throughout the water. Equipment and supplies had fallen from the station and were sinking to the bottom. The debris gradually drifted away, but the robot continued straight down, deeper and deeper. Roz heard a grinding noise coming from far below. The noise grew louder as she descended. Dust clouds appeared, and suddenly the poison tide was everywhere. She swam on, through the clouds, as the grinding noise grew louder still. When Roz emerged into clear water, she saw a steep mountain, rising from the depths. Strong currents blew off any sand and silt, and what remained were slopes of bare, craggy rock. Grinding across the mountaintop, stirring up those clouds of dust, was the mining robot.

At last, after months of searching, Roz had reached the source of the poison tide.
