>> the calf is eight months old and enormous, posing a serious threat to robert and mark's safety. >> they weigh 200 pounds when they're born, and this was eight months of good food and lots of mom's milk. >> we could not get in there, so our option was to use the ropes. >> their plan is to harness the calf with a rope attached to the jeep and pull. the calf has been in the well for hours and is exhausted. its mother is still nearby, so a quick rescue is essential. the calf has stirred up mud, and the sides of the pit are extremely slippery. >> i was terrified the rope would pull taut and one would trip and fall in with the baby calf. it's very dangerous. >> the baby elephant who they think is female, has turned toward the direction of its mother's cries, which unfortunately, is also the steepest side of the well. in the jeep, vicki describes what she's seeing.
