Rangitata Gorge Walk

Thurs 05.03.20. I did the Rangitata Gorge walk, halfway along to the highest point on Rangitata Gorge track (aka Tenahaun Track), map ref BX 557545, on the 500m contour, about 6 km return - 2h to my 3km turning point, 1,5h return. A sunny, windless day.

I drove 70 km from Pleasant Point, via Geraldine, crossed Rangitata River, upper bridge, and on the Mayfield Rd turned left along Ealing Montalto Rd, driving beside Mt Peel / Tara Haoa Range for about 20 kms, Mt Pukanui / Moorhouse Range straight ahead. I turned left at Klondyke Station turnoff & followed the Rangitata Diversion Race (RDR) canal along the canal dirt road for about 7 kms until the road ended at a DOC carpark, several signs at the entrance gate fence: RDR history info, DOC easement, Fish & Game Angler Access, Protect Our Waterways - Didymo... Outdoor Access video surveillance signs...

          Rangitata to Rakaia Diversion Race

IPENZ recognises this engineering work as an
important part of NZ's engineering heritage.
Approved in 1936 to provide employment relief &
a vision for Canterbury's future, this 67 km race was
the first major river diversion for development of
water resources. It supplies 66,000 hectares as well
         as 27 MW of hydro power in winter...
                                                             Opened 1945.

Besides Rangitata River & the RDR canal I wandered past 2 bucket cranes, one under a green canopy & surrounded by a fence, NO ENTRY signs on the fence. The RDR inlet had several DANGER signs on a fence above the inlet: KEEP OUT AUTHORISED PERSONS ONLY...

From the river terrace above the RDR inlet, I watched 5 rubber rafts, filled with thrill seekers, shoot the rocky weir across Rangitata River, flowing partly into the RDR inlet & mostly along its river course to the Pacific. Also from the terrace, I watched a farmer across the river in his blue ute & his 3 huntaways herd red deer down 3 river terraces through a farm gate on a lower Rangitata River terrace. The huntaways ran like wolves.

The DOC easement track followed a farm fence along the E lip of Rangitata Gorge & sidled W side of Mt Pukanui & Moorhouse Range with grand views of Rangitata River running several rapids between Waikari Hills W & Moorhouse Range E. Waikari Hills' vertical strata showed tortured seismic activity over geological time.

After the the second farm gate, above a Flying Fox over Rangitata Gorge, the DOC easement track became bogged by Hereford herd pugs, so I climbed through the farm fence & walked through matagouri scrub on farmland, a safer stretch, avoiding cattle pollution & the potential for being trampled by the Hereford herd gathered on a gorge ridge at another farm gate on the DOC easement.

I climbed through another farm fence to a sheep paddock below Moorhouse Range & wandered the sheep-muddy, 500m contour track, across steep ridges to my 3km turning point, the track eventually leaving Rangitata Gorge. Grand views of Harper Range at the head of Rangitata Gorge.
