Big Ben Range ZL3/CB-857 6th November 2021

 This is an un-named summit in the Korowai/Torlesse Tussocklands Park. It's the peak NE of Ben More and 5m higher, hence why we were headed there! We had a false start a few weeks ago when a dump of rain on the Friday meant that it was too icy to attempt. No problems this time and, with an improving forecast, we headed up to Lake Lyndon for a nice early start. DOC has closed vehicle access to the area so it was a case of parking on the Lyndon road 1km past the Lyndon Lodge turnoff (near the "Z" bend).

Dave ZL3DRN did the first activation of this summit so we used his GPX route up a very steep (51% grade) initial climb to attain the ridge. After that it's  a much easier route up the ridge to the summit. All the while looking south at the route he had planned for our descent - more on that later...

We made good time up to the summit - my climbing fitness is certainly improving, arriving about 1.5 hours before our alerted time... Regular readers will notice a pattern here. As forecast, the Canterbury Plains were blanketed in thick cloud but we had spectacular views of the mountains around us.

Christchurch is out there somewhere! Nice up here at 1660m ASL though.

We used the Repeater hut as shelter from the very light breeze and set up the gear - antenna du jour is the 40m EFHW with switchable 60m loading coil designed by Stephan HB9EAJ. I really like this antenna for it's ease of setup, End Fed convenience and it's fairly light weight. Oh, and it's resonant on 7 bands!

John ZL3MR was on Mt Barrosa ZL3/CB-499 and had also arrived early. Even though Mt Hutt was directly in the way, we managed 2m S2S contacts with him. The Christchurch gang were quickly worked on 2m also and then we hit the HF bands. We weren't expecting much given the Geomagnetic storm but it worked out OK with nice S2S contacts with Andrew VK1AD/2 and Matt ZL3NVW. Also worked were VK1MA, VK1MCW, VK5PAS, VK5IS and JA5QJX/0 plus our loyal ZLs on 40m and 60m.

Our summit peace and quiet had been invaded by a large, noisy tramping club group so we packed up and headed across the saddle to Ben More for lunch. (Unfortunately so did the other group!). It's a nice summit too with the remains of a trig and great views.

The rest of the route home was great, walking along the tops with spectacular views either side, what's not to like?!
Route home is via the long ridge to the left of shot. The ridge we ascended is the scrubby one on the right. Lake Coleridge in the background with Peak Hill CB-542 in the background.

Apart from a fairly steep scramble down the last spur (36%) and a real bash/crawl through some Matagouri (in flower so at least it smelled nice!) after crossing the Acheron River, we made good time down and back to the vehicle. A quick stop at Lake Lyndon for a fish (unrewarded) on the way out and we were off home after another epic day. Thanks Dave for pushing me to extend my limits.

Summary:
15.8 km walked
1307 vertical metres
4 Hours 51 min walking time

Getting there: Head over Porters Pass on State highway 73 before turning left at Lake Lyndon and driving about 5 kilometres. Just before the road turns hard right (Z corner) right there is an area you can park. Note that vehicle access is not permitted into the park itself now. 

Permission: None needed - Korowai/Torlesse Tussocklands Park

Trig: None, repeater station on the summit

Cell Coverage: None until at the summit. Spark better than Vodafone but still very patchy.

Repeaters: 705 and 2m simplex to Christchurch is easy - direct line of sight.

Time to the top: Allow 3 to 3.5 hours up. It is a 6.3km walk up with 941m of climbing.


Update: Thanks to Dave for the photo of me in the Matagouri, it was pretty tough going!
