McGills Creek is so little known it does not even feature on New Zealand's topographical maps.
But, now a large rock and a plaque mark where it is, in the Matukituki Valley, west of Wanaka.
It was up the creek in April 1963 20 venison hunters shot 200 deer.
The deer were carried out of the mountains by American Milton Sill in a Bell helicopter, proving for the first time the value to the export industry of using helicopters to recover wild venison.
Half of the deer ended up on the dinner plates of New Yorkers.
