Tararua Footprints Online

Many people who visit the Tararuas will have a copy of Merv Rodgers’ book from 1996, Tararua Footprints, on their bookshelf. Historically it’s one of the more authoritative guidebooks on the Tararuas, talking about river systems and valleys and how the routes fit together. It covers different territory from the more recently published Tararua Adventure Guide, which is a more specific guide to specific things to do in the range.

Lately, Tararua Footprints has become very hard to track down, but very awesomely the author has now donated the text to the Tararua Tramping Club for a new online edition.

Although it’s now 16 years out of date, geography doesn’t change much in that time and most of the information is still very relevant. The longer term intent of the TTC is to turn the online edition of the book into an up-to-date working guide to be edited in an ongoing fashion and be the “definitive Tararua Range route guide”.

It’s certainly worth checking out next time you venture into the Tararuas.

Heuristic Traps of the Tongariro Alpine Crossing

Departing from South Crater
Leaving South Crater near
the end of spring.

A rescue that may have been inevitable occurred in Tongariro National Park on Saturday, when 16 people were rescued from the Tongariro Crossing, at least four of whom were in early stages of hypothermia. Present media appear to be pushing an angle that assigns much blame to a shuttle operator (who also has a side of the story) for giving the group incorrect advice about weather, although that’s something I struggle to accept. [Update 5/5/2012: This morning the Dominion Post also weighed in with an editorial, which largely blames the shuttle operator, but which I also think ignores much of the problem.]

“It got very nasty very quickly, and we became separated into three groups.

“We had the strong wind at our backs and we didn’t want to turn back into a headwind.”

Their hands became so cold that it became too difficult to open their packs to find food.

It was not until a woman collapsed with hypothermia that they decided to head back, he said.

Two Auckland trampers, Ghaz Jabur and Graham Plows, found the confused and hysterical group late in the morning and helped them off the mountain. They also contacted police by cellphone.

“The visibility was down to 10 to 20 metres; it was a freezing wind and we were crouching behind this boulder when we saw this hysterical person coming towards us,” Mr Jabur said. “We asked him if he was alone and he said he was with a big party who were trapped further up.”

The men grabbed their packs and climbed up to find the group huddled together. “They were hysterical; they had minimal clothing on – puffer jackets, hoodies, jeans, tights and sandshoes.”

The men gave spare clothes they had in their packs to the worst-affected and tried to get them out of the wind.

“All we could do was grab them and pull them down the slope. We did this for about 10 to 20 minutes, it was totally exhausting.

“Two guys and two of the girls were in a really bad way. They were shaking involuntarily, they had hypothermia and their eyes were rolling. They couldn’t put food in their mouths; they would have died for sure.

“The only way we could get their attention was to scream at them one at a time and tell them what to do.”

For me, it’s a reminder that the Tongariro Crossing is one of the wackiest places I’ve been in New Zealand in terms of seeing unprepared people in a wild, potentially very isolated, changeable and dangerous environment. I wrote about this problem of inexperience combined with popularity at the Tongariro Crossing a couple of years ago, and this TVNZ Close Up story from a few months before impresses the extent of the problem.

It’d be premature to try to comment on specifics of exactly what happened with regard to advice given, but I’m not entirely sure it’s relevant. While it’s good to have responsible people on the edges, assigning blame to operators for dropping off and collecting people who aren’t prepared also ignores the bulk of the problem.

That said, it also feels simplistic to just assign blame to people themselves and go no further—there are bigger things happening. Even if 16 people found themselves in trouble and had inadequate clothing and weren’t properly aware of the forecast and nearly died, and even if it is their own fault, they still weren’t doing anything especially different from what a substantial proportion of people have been doing before them and will likely continue to do in the future. In that respect, these people just happened to be the unlucky ones out of the crowd. For me, that is a much bigger problem, and this incident is merely symptomatic.

Proposed Tararua Cycle Track

The Dominion Post and the Manawatu Standard both carried the story of a proposal to build a cycle track through the northern Tararua Range, between Shannon, into the Mangahao Dams and out to Ehetahuna. It turns out that this idea has been around for at least a couple of years (and here’s an earlier article on Stuff), although it’s the first time I’ve noticed it myself.

The map, taken from a 14MB PDF hosted on Stuff, doesn’t give much detail and I’m having some trouble matching the squiggles to realistic geographic terrain on the topo map of the area. I think the proposed route from west to east appears to enter the range from Kakariki West Road or nearby, climbs up Pohehe and Ratapu, up to Ngamaia and Conical Knob, then around Massey Knob and Ngapuketurua. From here, I’m guessing the idea is to head down a spur via spot-heights 959 and 851, 675 and 670 to get to Harris Creek, and follow the Mangahao River back to the dams and out to Shannon. Apparently the plan would involve building a hut around Ngapuketurua.

Kime Hut Replacement is Actually Happening

IMG_7735
Visiting Kime Hut at 9pm
on a winter’s night.

For several years now there have been rumours that Kime Hut would be replaced, and they’ve been subsequently quashed or pushed back for one reason or another. (Budget issues and such.) This summer, the rumours seem to be formulating into something that actually occurring. Kime Hut is in a very exposed part of the Tararuas, and serves as a stopping point for some as part of the Tararua Southern Crossing. The hut has a big internal space and its reputation is one of being a very cold place to stay, and although it can keep off the most harsh aspects of a storm, it’s also sometimes referred to as the refrigerator—on this occasion in 2009, Craig measured the indoor temperature to be approximately 1°C warmer than the outdoor temperature. It’s fairly common to hear people pleading for some form of heating in the hut, but that’s never happened.

Last week (after I asked) I was very helpfully informed by one of the local staff at DoC’s Kapiti Conservancy that yes, Kime Hut is going to be replaced during the summer of 2012/2013.

Daywalk: Up Mount Reeves

IMG_0929
Meow.

With a day to spare in Wellington, I had a thought of attempting to find Snowy Hut in the Tararuas, which I’d be keen to see some day simply through virtue of it not officially existing. To do so would involve some river travel, though, and with a forecast that would allow little if any room for error or mistake, lest becoming totally screwed by a severe storm due to come in by evening, I reluctantly decided it’d be a bad idea. This led to plan B, which was a jaunt up to Mount Reeves, which is mostly under trees, involves no rivers, and should be easy enough to retreat from if the storm came in early. I’ve never been up Reeves Track before. (Maybe there’s a reason.)

Thus on Friday morning, I drove to the end of Waiohine Valley Road, behind Greytown and near Woodside Railway Station, and parked next to a herd of unrestful cattle. So far, so good. No sign of stormy weather, and a little sunshine.

Date: 2nd March, 2012
Location: Tararua Forest Park, Waiohine Valley Road.
People: Just me.
Huts visited: None.
Route: From Waiohine Road, up the Mt Reeves Track past Rocky Knob to Mt Reeves, then back again.

Leaving behind the farm.

Soon after sorting my tramping outfit, shortly after 10am, the local farmer drove up on a 4 wheel motorbike. It turned out he was about to move the moo moos to a new paddock. He reckoned where I’d parked the car was fine, but I soon found myself being closely followed up the farm track. There would’ve been a few nice scenic photos of the Waiohine River down below, if I hadn’t been stumbling with camera batteries.

A nice New Zealand LandSAR documentary

I may be late again, but it’s nice to discover that someone’s recently made a sane, down-to-earth documentary about New Zealand’s voluntary LandSAR Organisation. It makes a nice change from some of the overseas Search and Rescue videos I’ve come across which often seem to be artificial self-promoting noisy-overvoice and patriotic-music productions that focus on SAR being an heroic high risk profession, and which emphasise elevation of SAR above common people, to be left only for professionals. This NZ LandSAR documentary, on the other hand, spends much time interviewing people who take part, and emphasising how LandSAR is made of regular people with normal jobs. It provides actual information, instead of slow-motion closeups on actresses hopelessly weeping about lost husbands. Hooray!

Detecting a faulty baseplate compass

A Silva Field 7 Baseplate Compass
My Silva Field 7 Baseplate Compass.

Usually when intuition says one thing and a compass says something else, it means your intuition is wrong. More than a few times, I or a group I’ve been in have had a compass bearing telling us to go one way that intuitively seemed completely wrong, and after some time it’s turned out that we really were meant to push through an area that looked completely un-navigable. A couple of times, my sense of direction has become bizarrely flipped somehow inside my head, only to be corrected by a compass. On occasion, this has resulted in my sitting down in a flummoxed state for a few minutes trying to flip my head over, but it usually works out.

One problem with a compass, though, is that the needle can occasionally flip—the south pole of the needle becomes north, and north becomes south, meaning the red end of the compass points south instead of north. This is exactly what happened to me on this occasion. The needle flipping actually happened some time before I left, and happened to be wrong when I first pulled it out to use it whilst inside visually encumbering cloud at 1400 metres elevation. Flipped needles are often a consequence of exposure to iron, in the same way that you can easily magnetise a pin by stroking it with a magnet a few times. In my case, I didn’t have a clue what’d caused it because my compass spends most of its time sitting on a shelf, but there are many things that might have caused it. Clearly this can be a problem, and if you’re trying to navigate it can also be a little risky if you’ve not realised what’s happening.

There are a few ways to detect this in the field, though, and I’m keen to hear of any that I don’t mention here. Obviously if you know where you are and can see a known landmark, you can compare the compass to see if the needle’s pointing where you’d expect. If you have multiple compasses, you can compare them and at the very least determine if one compass is misbehaving. In my case, the first sign was that it tried to point me directly back the way I’d just come from, but in most such cases I’d still expect a compass to be more correct than my own intuition. Fortunately my GPS (usually packed away) includes an electronic magnetic compass, which I spent a few minutes calibrating, then compared the two.

There’s yet another sign which might be common knowledge, but I can’t find any references on the ‘net so I thought I might share it. What should have been a dead giveaway for arousing suspicion in my case, especially in hindsight, was that the weighting of the needle within the compass was completely wrong.

Research of Interesting Outdoor Whistles

Several years ago, and soon after a couple of occasions when I’d wanted a whistle on very short notice but didn’t have one, I went out to buy a whistle to attach to my pack. With very little research I bought a Fox40 Classic whistle because it was easy to find and because their marketing said they were fantastic, and also that they were the "standard choice for personal safety and rescue professionals worldwide". Besides giving me greater opportunities to annoy people, I thought that maybe it’d be useful in a SAR situation some day, too.

Sadly I felt let down after some time. Despite the Fox40′s ability to momentarily deafen me any time I blew it, I found it often didn’t annoy people at a distance in an open space, or even reach their ears, as much as I hoped. I put this down to various issues in the bush, like the frequency of corners little hillocks around which sound probably wouldn’t be travelling well, and probably also some audio absorbing properties of thick vegetation. Recently though, I was pointed to some research that’s been done on whistles, and (even better) it’s about the effectiveness of different whistles in New Zealand back-country conditions.

Specifically, in 2006 a group of New Zealand Youth Search and Rescue members ran tests that compared a variety of whistles, as well as a giant honker and “yelling and screaming”. The tests have very recently been updated in 2012 to include comparisons of some extra whistles that were provided by Safety Whistles NZ.

From personal experience I’m not surprised in hindsight that the Fox40 whistle tested badly, coming 6th out of 7 whistles and (after the 2012 tests) being barely comparable with a newly tested Safety Whistle. I was surprised by a couple of things, though.

Daywalk: Hovering around Pouakai Hut, Henry Peak and the Pouakai Summit

IMG_0804
Looking back from
near Pouakai Summit.

Returning from the West Island for a week and a half, I found some time to wander more in the vicinity of Eggie—also one of New Zealand’s cultural centres of insane mountain running.

I’d been up to the summit a little over a year ago, and this time the weather wasn’t exactly cooperating for that. Instead, I decided to wander up an easy route towards Pouakai Hut and find somewhere to read my book for the day. For a more complete description of the area, there’s a write-up of a variant of the Pouakai Circuit in late 2010, during which anyone who reads carefully will note it did not rain at all.

Date: 28th February, 2012
Location: Egmont National Park, above Mangorei Road.
People: Just me.
Huts visited: Pouakai Hut (0 nights).
Route: Up from Mangorei Road past Pouakai Hut, up Pouakai Summit, then back and up Henry Peak, and down to road again via hut.

Having parked at the end of the public part of Mangorei Road (there’s a 350 metre walk along a non-public driveway to the park entrance), I sorted things out and began the climb up the Mangorei Track at about 10.15am, just as the rain began. No matter, as it’s under trees for some time yet and I waved to one of the nearby residents as they drove past whilst I struggled with my raincoat.

Just for a few days

I’ve been back in New Zealand for the last few days. We came back mostly for a wedding (in the Coromandel) which has been and gone. After that we drove down the North Island via Taranaki, turning many corners and driving over many hills, which is something else I’ve really missed. Thankfully the frequent Taranaki sunshine relented for a day, providing an unusual day of low cloud and heavy rain for me to hop up towards the mountain and read a few pages my book. I’ll write something more properly about that later once I have a chance.

Now I’m in Wellington for a few days, just hanging around and enjoying the place.
