RESCUE OF AN ELEPHANT FROM A WELL IN KINANGO AREA 2nd OCTOBER.

Reports were received from Voi radio room of an elephant stranded in a water hole while searching for water, the vet team together with assistance from rangers arrived in the area that evening. The male elephant was seen struggling to climb out of the water hole in vain.

Operation Elephant out!

The muddy water hole was very slippery and the elephants attempts all proved futile! Several attempts to pull it out using a land cruiser failed and the team finally resorted to the use of a truck!

Attempts to pull him out were frustrated by the tendency of the elephant holding onto the rope and equally pulling it towards the water hole!

After about twenty minutes of struggle he was finally pulled out to the relief of everyone who was participating.

He calmly removed the ropes from his body and happily ran off to the bushes!  He was out and with no injuries!!
