Lower Olderog biv (aka Jade biv) Feb 2009
This biv is located on a bench well above the creek bed in the headwaters of Jade Creek. It is on the TL in the scrub zone close to lightly/unvegetated ultramafic rock screes that give reasonable access to the tussock country. Jade Creek is a tributary of Olderog Creek which in turn is a tributary of the Arahura River.
Jade Creek below the biv cuts across a band of ultramafic rock exposing reef jade and washing boulders down stream. This area has been one of NZ's major sources of jade since pre European times. There are jade miners huts closer to the creek below this biv.
