Environmental Impact

The impact on Erebus was reduced this year by the removal of disused microphones from the mountain side, and the return of about 12 reels of spare rope and wire from the upper hut to New Zealand. There is now very little unused equipment or materials on the volcano, and that in use is neat and tidy. The previous transmitter site at the summit of Tenor, which was out of helicopter range from December 1986 until 1989, has been cleared completely and returned to normal.
