Coal Hill ZL3/CB-419 and Blacksmith Spur ZL3/CB-440 circuit April 2022

 I've been looking at doing these two 6 point summits as a circuit for a while. Mark ZL3AB did them first as an "out and back" in 2019 and documented it here

I managed to talk Francie into acting as shuttle driver - dropping Dave and I off at the start point of the Coal Hill track easement at 8am on a frosty April morning. That necessitated a 5am alarm but as a bonus, she got to spend the day shopping in Ashburton with her mother. Good deal!

The track starts through farmland across a couple of small gullies and then a steady climb to Coal Hill summit. It's a well marked route (poled) but basically you simply follow the fence-line straight up a spur to the summit. We were on the top in 2 hours, only stopping to chat to a couple of hunters stalking Tahr just below the summit. We exchanged planned routes and moved on to set up on a sunny but still chilly summit around 10 am local time. HF antenna was the 44' doublet and on 2m, the Signal Stick 1/4 wave with counterpoise ("rats tail"). 2m was line-of-sight to Christchurch so I qualified the summit quickly on 2m (including summit-to-summit with Ian ZL3GIG on Saddle Hill) while Dave hit 40m SSB. Once Dave had worn out 40m, I took over and worked the ZL chasers on 40m CW before switching to 20m. Caught up with the usual VK team and then a mini-pileup of Europeans ensued with Finland, France and The Netherlands in the log in quick succession - happy days! 

Conscious of the need to keep moving (and the fact that my fingers were frozen) we packed up and headed across the ridge towards Blacksmith Spur. Plenty of gunshots echoing around the valley - hopefully our mates had got onto their target species!

Looking back along the ridge to Coal Hill

The ridge has about 280m of vertical included but we made good time and were on the next summit 30 minutes early at 12:30 pm local. A convenient boundary fence post supported the antenna and we were away again with plenty of contacts back to Christchurch on 2m and NZ and Australia on 40/20m.

We chose our operating positions on both summits to ensure we were inside the Mt Peel/Waikari Hills Conservation Area ZLFF-0022 and it paid off as we worked a number of VK stations chasing the WWFF reference which adds to the enjoyment. 

6m pole bungeed to the post 44' doublet antenna and open wire feeder.

Conscious of Mark's warning about the state of the return track down through Rawle Gully, we grabbed a bite of lunch and set off down. The first part is straightforward, follow the park boundary fence down the spur towards the gully. The last bit is near-vertical and, combined with wet grass and mud, very slippery. Both of us ended up on our backsides and ended up holding onto the fence most of the way down!

Hanging on to the fence was a good option down here...

The entry point into the riverbed is well marked but poles are a bit sparse after that and after some bush bashing, we found the markers again just before arriving at the exit point and our ride home! It's a good 2 hours down from the summit.

A really good day out. 12 points in the bag, 12km and 1360m of vertical into the legs.

Getting there: Past Peel Forest and into the Rangitata Gorge Road. Drive past two "Z" corners and along a straight to the Coal Hill track start (DOC Sign). -43.755163 171.159353

Climb is 2 hours to Coal Hill (DOC sign says 3 hours), 3.2km and 1074m vertical gain.

Ridge to Blacksmith Spur is 1 hour 15 minutes, 4km and 276m vertical

Descent from Blacksmith Spur to Rawle Gully bridge took us 2 hours (wet), 4.6 km and 992m descent

Cell reception is patchy on both summits. Sometimes 4G and sometimes not even SMS.
