Kime Hut Temperature Experiments

This past weekend, I was on a tramping trip with the WTMC and we passed through the “new Kime Hut” twice due to the gale force winds turning us back at Mt Hector. Yes, another failed attempt at the Neill-Winchcombe Ridge.

These were of course my first visits to the “new Kime Hut”. It is located above the bushline, without any source of fuel for a fire. Without any heating it was bitterly cold inside and as an alpine hut, so I decided to repeat a past experiment of measuring the temperature inside and outside the hut. Each time leaving the thermometer away from body heat for 5-10 minutes before taking a reading.  From these measurements I learned that every trampers hope that the new Hut would be warmer have been dashed. If “old Kime Hut” was “The Fridge” then “new Kime Hut” must surely be The Chiller. I certainly do not possess scientifically calibrated equipment, and the table below is based on very few samples. However, it does show a clear pattern - that the new Hut has not broken from the heritage and legend of the infamously cold Hut that is recently replaced.

Ruapehu Crater Lake: Summer & Winter

This past weekend I completed the second weekend of a Snowcraft course with the Wellington Tramping & Mountaineering Club. On Saturday we had good weather and made it up to the Crater Lake at the top of Mt Ruapehu. Having previously visited these parts in the height of summer, I thought contrasting the summer and winter photos from the same location would be interesting.

Tramp: The Moonlight Southern Crossing

After a few false starts on the fourth? attempt I finally completed the Moonlight Southern Crossing. Prior attempts having been thwarted by weather and well, a sheer lack of Moonlight.

Trip Data:
Distance: 37km  
Time:

12:56:51 (moving)

21:40:31 (elapsed)

Elevation: Ascent: 2,357m Descent: 2,224m
Trip Data: Garmin Connect
Location: Tararua Range, NZ 24 July 2010

It is hard to say exactly what it is that gives this trip its magical appeal. Perhaps it is the statistical unlikelihood of having a clear night in the Tararua Range during the middle of winter? Let alone underneath the full moon! The Tararua’s are renowned for their imperfect weather,  as Geoff Spearpoint observed in his book “Waking to the Hills”

Weather plays a major part in Tararua affairs, mist normally covering the tops for 250 days of the year. Southerlies bring the snow and freeze them; westerlies bring the rain and wet them; and the northerlies blow until it is a marvel there is anything left.

I had arranged to do this trip with Mike and Sam, and we were all watchful of the weather forecasts and weather model information in the week leading up to July's full moon. The best weather looked like it would be on Sunday evening, but the storm passed through quicker than expected over Friday night, Saturday was a cracker of day.

 

Sam and I hatched a very approximate plan over the telephone which optimistically featured the fastest times we had travelled over each section of the route. Oooopps. Not the best way to estimate time! At least walking straight through, without staying in any huts saved me from having to splash out on the recently increased price for a new annual hut pass.

 

Flat battery number one: After seven weeks of being an incredibly fuel efficient Subaru - stationary on my driveway! The battery was dead and would not turn the motor over. Thankyou awesome neighbour Ken for helping me out so we could go tramping! I must say I do prefer to walk or to cycle, but must make sure I the car moves out of the driveway at least occasionally!

 

I collected Mike and Sam enroute to Otaki Forks. Oooopps battery issue two: I had not replaced the batteries in my SPOT after removing them before flying back from the USA recently.  Sorry - no digital breadcrumbs for the worrying family at home. No problem as long as we do not need that SOS button!

 

Shortly after crossing the bridge over the Waiotauru River we saw Spencer, whom I had not seen for a couple of years. He reported ice on top; crampons recommended; couldn't get into Kime Hut as it is frozen over. We noted that regardless of the not so balmy conditions he had reported that he had travelled without an ice-axe. After a quick chat Spencer kindly drove my car back to Wellington to save me the effort of returning to Otaki Forks to collect it!

 

A few minutes before reaching Field Hut darkness encroached as we travelled for our last few minutes in the bushline with the use of our headlamps. Once beyond Field Hut and above the bushline the moonlight provided enjoyable conditions under a beautiful night sky.

 

With Mike on the trip and his knowledge of astronomy we were able to celestials the prominent celestial body in the sky to our west. All without needing to refer to Wikipedia to pretend to be smart. Now above the bushline we had Venus as a prominent celestial body to the west.

 

The lack of snow was notable as we walked across Table Top. At this time it was difficult to co-relate with Spencer's crampons recommendation. There were a few patches of firm snow as we crossed Dennan followed by thin layers of snow leading to Kime Hut. There was substantially less snow than when I was here last year, however, on this occasion it was much nearer to frozen and a lot more slippery.

Upon reaching Kime Hut the door was frozen shut, just as Spencer had warned.  Sam used his ice-axe to remove the frozen ice from the large metal latch to gain entry. I was pleased to have thought ahead by carrying extra fluid with the Kime Hut water tank frozen solid, which was always going to be likely at this time of year.

 

Departing Kime it was onward and over Field Peak (which counter-intuitively is nowhere near Field Hut of course). Once reaching the descent of Field Peak on it's southern side it was icy and slippery. Once again, just as Spencer had advised. My ice-axe has been on many more trips than it's been required in the past. Tonight it was essential to assist my rather less than assured footing on this mixture of ice and rock.

 IMG_7757

There was some cloud about when we reached the summit of Hector and the memorial cross, but not enough to block the light of the moon, or as Mike would prefer to correct me, the light of the sun reflecting from the moon.

 

As we descended Hector and made our way through the Beehives, the track itself was a little treacherous having formerly being wet, but now was frozen solid. Where possible we walked on the safer route over the tussock alongside the frozen track. Where rock covered in 'black-ice' was the only option my steps were far more tentative, as I grovelled through with my ice-axe held by clenched iron-fists. This made progress pretty slow. Ideally there would either be lots of snow to make crampons ideal, or no snow at all. The mixture of snow and rock as tricky, particularly on

 

Once over Atkinson there was a lot less ice around as we continued around the Dress Circle and over Aston, now with Jupiter clearly visible to the south east. Once at the top of Alpha where there was no snow or ice at all. We spent a few moments relaxing on top of Alpha. Enjoying the night sky and the still air which is so rare in the Tararuas Range.

 

We approached Alpha Hut quietly, but found it empty on this glorious evening.  Without needing to worry about disturbing others, we had a reasonably long rest an a snack before departing a little after 4am. We were already a long way behind our intended, and optimistic time but only had the Marchant Ridge left between us and our destination at Kaitoke.

 

The Marchant Ridge an area of geography that often subject to much slander among trampers. I have often felt this is this isn't necessarily justified. Many trampers lament the lack of views on this goblin forest coated ridge, yet the goblin forest of the nearby Cone Ridge celebrated. With the Marchant so often described with, well lets just say with many short err, "adjectives". The current topographical map BP33 shows eight spot heights along this ridge, with a mere150m of altitude descended between the first last of these. It certainly seems to be with some justification that many describe this ridge as:

'Uphill in both directions'.

However, I believe that the real reason ridge is so despised is because it is both long and at the end of epic journeys. The Marchant Ridge often being the final stretch of a  Southern Crossing or an 'SK' and it is some 15km long. The mind says you are nearly there, but in reality you are not. The route from Alpha Hut to Kaitoke along the Marchant Ridge covers 40% of the total distance over the Southern Crossing route!

 IMG_7781

 

On this occasion, I stepped in a hole somewhere near the 'top' of Marchant Ridge. After wincing and limping for a few strides, at which time I felt like rolling over the ground screaming like a girl, I just kept walking. The further we went the more my knee swelled. I was unsure if I had an injury, or if a less ambitious trip would have been more desirable after not having been out tramping for a while.  I just kept on moving. The sun was rising by the time we reached the open area on Marchant that was created by a fire here some years ago.  and eventually we found our way to Kaitoke over 21 hours after leaving the car in Otaki.

 

This was a much slower trip than we had optimistically anticipated. That said the GPS data that Mike collected suggests we only spent about 13 hours actually moving - the rest of the time Mike and Sam must have been waiting for me? While they *did* spend a lot of time waiting for me, I’m not sure it was quite accurate!

 

 

Thankfully about a week later the swelling in my knee came down and I can once again see my knee cap – phew!.

Thanks Mike for the photos and GPX file. You can read more about this trip on Mike’s blog at http://www.windy.gen.nz/index.php/archives/487#more-487

And thankyou for leading the trip Sam :)

Day walk: Ruapehu Crater Lake

I was in Ohakune for the Ruapehu Classic which I cycled yesterday. Earlier in the week at work when I was looking at the weather maps and said I would go up Mt Ruapehu’s Crater Lake, my friend and colleague Mike said he would like meet me on Sunday and come along too, well it was more up than along actually :D.

 

When arriving at Iwikau Village at “the top of the Bruce”, the Bruce Road being the road up to the ski-fields of the Whakapapa side of Mt Ruapehu it was less familiar than it should have been for both of us, considering that we had been here many times before - in winter for snowcraft courses and mid-winter alpine trips with the Wellington Tramping & Mountaineering Club. On this occasion the volcanic rocks were not covered in snow and ice. This side of the mountain, with all the ski-field infrastructure had a relatively industrial appearance.

 

We followed a route up the Rock Garden underneath the Rock Garden and Waterfall Express chair-lifts with the occasional conversation heard above us as others had chosen use the chair-lifts instead a pleasant one hour walk to begin the day. Actually, we must have been the only self-respecting trampers on the mountain today as we did not see anyone else walking from the car-park to the top of the Waterfall Express chair-lift. When we reached the top of the chair-lift it was an industrial looking site with a digger present and construction of a new cafe for the pending winter ski season underway. This is part of the effort to repair damage from arson attacks in early 2009.

As documented by DOC there is no official marked route to the summit. No problem, Mike and I had our brand-new Topo50 BJ34 Ruapehu maps and about three sentences of vague route information from one of Mike’s books. The three vague sentences were especially “useful” since each place name mentioned was not named on the Topo50 BJ34 Ruapehu map. After the trip I checked the older 260 series T20 Ruapehu map and they were not named on that map either. This wasn’t a problem. I took a very rough bearing to where we needed to go. Actually, it was such a rough bearing that Mike mocked me for moving the map as I rotated the compass dial. This sent us following the Knoll Ridge t-bar and approximately along the Knoll Ridge route from Mike’s book. With no official route to follow we had no problem complying with Craig’s three rules for off-track travel:

  1. Travel in the correct direction
  2. Choose a easy route - we’re tramping not rock-climbing!
  3. Avoid bluffs and other insurmountable obstacles

Having not done a lot of tramping recently I certainly was not able to travel as quick as Mike. No problem, I know that Mike likes to play with his camera, so this allowed him plenty of time :D.

 

Being the height of summer, with the exception of a couple of snow filled gullies there wasn’t any snow to travel over.

 

As we approached Glacier Knob, we most likely chose the harder route by going directly up a scree slope when we could have sidled around it, to ultimately arrive at the same saddle. from the saddle a worn path around to Dome Shelter Equipment Shed. That said, our higher route provided a splendid view of the Summit Plateau and Cathedral Rocks before it was obscured from incoming cloud. Sidling around the side of a hill always feels a bit unnatural to me and when in doubt I always take a spur or ridge straight to the top.

 

Now at over 2600m a conversation ensured about the highest places we had been and how we got there.

  • Craig: This is the highest altitude that I have been at except in a aircraft.
  • Mike: Having been over the Andes in a bus, this is the highest I have been unless in an aircraft, or a bus

Following the worn path from the saddle below Glacier Knob we arrived at Dome Shelter and the sat above a view of the Crater Lake. Not that we could tell this immediately, since the cloud had moved in and surrounded us. As we nibbled our lunch, and some less deliberate high protein insect garnishes the cloud drifted in and out revealing excellent views over the Crater Lake and across to the Cathedral Rocks.

 

This is when we met Graham and Jane who were on holiday from the UK. From what

we could gather, they had arrived here via Te Heuheu after following the east-most t-bar (if I were a skier I may know what this one is called), and joining Pinnacle Ridge at some point above the pinnacles from which the ridge is named. Graham’s boots were falling apart. The small hole developing in mine was no contest for his complete adhesive failure on the soles of both boots! The grippy part was gone and he was now wearing our the squishy bit before getting down to the inner-soles and then his bare feet. Jane mentioned that it would be nice to know that were some other people around on their way down. I think she was a little more exhausted than I realised at the time.

 

On the way down we picked up a trail from the saddle below Glacier Knob that led down the Restful Ridge route. We caught up to Jane as she was slightly nervously descending a snow filled gully. This is by no means unusual for people who have descended snow a lot. Mike and I assisted her down the snow section as both Graham and Jane were becoming concerned with reaching the chair-lift before it stopped operating at 4pm.

 

After the snow section Mike and I ended up a little ahead, and following our noses headed further eastward to get back to the Waterfall t-bar that leads toward the Waterfall Express chair-lift. Having now lost sight if our British visitors we turned to see which route they were taking. They appeared to be moving toward a different chair-lift that was not operating, and also in a direction that was not  a direct-line toward the car-park. While the conditions were good and their should have been sufficient time and light for them to change their direction and reach the car-park, knowing that they were tired and now probably suffering from a case of get-there-itice, it did seem prudent to assist them back to the Waterfall Express chair-lift. It wasn’t until we arrived home to Wellington that we read the media reports of a Greek tourist who had spent the previous night on the mountain. We scrambled down the moraine to where they were and assisted them in the direction of the chair-lift. Mike went ahead to let the chairlift operator know that we were coming and not to stop it. We were scampering over moraine less straight forward than where we had been but we were travelling in the right direction and managed to thread our way between the undesirably steep sections before crossing the stream, and onto a track in front of mound hosting the Alpine Club Hut. Form here there was a more worn route directed us to the Waterfall Express chairlift.

 

Once at the chairlift, the friendly chair-lift operator, Jane and Graham convinced Mike and I to take the lift instead of walking as we had intended. Incidentally, the chairlift operator was also a marshal from the Ruapehu Classic cycle event the day before :).  About 13 minutes down via the Waterfall Express and Rock Garden chair’s was probably saved us about half an hour of walking.

 

Once back at the carpark, Jane and Graham kindly made us some coffee in their campervan which we enjoyed before the long drive back to Wellington. Thanks for the coffee, I hope you found some boots and that you are enjoying the rest of your holiday.

Tararua Forest Park: Kime by Moonlight

From Kime by Moonlight


With the full moon visible in the clear blue afternoon sky, snow on the top of the Tararuas I left work early. Could I finally get over the Southern Crossing under the moon? For so long I had waited for the full moon, clear skies and snow all at once. I had to make the most of the opportunity.

I packed my things together and headed for Otaki Forks. As I departed over the new Waiotauru footbridge I was on my way. I almost felt disorientated as I walked along the track "improvements" and past the digger used in their construction. I had been over this track tens of times before but, it now seems as wide than the Otaki Gorge Road that leads here.

There were no concerns about freezing on this windless evening, and wearing a layer too many of polypro I was soon sweating my way up to Field Hut. The carnage and tree falls from the previous time I was here has been cleared from the track, but the remaining patches of thin tree canopy from that storm were notable.

After a short break at Field Hut the ascent continued. I was soon on Table Top under the full moon and mostly clear sky. I was still hopeful of finding some snow as up to this point it has been noticeably absent. Approaching Dennan, I was finally into the snowline at about 1200m. I was having a great time in the snow under the moon. It was awesome. In the excitement and heavy snow I managed to via away from the established track, with, like my politics a slight left-hand bias. After a brief right-hand correction I was back on the established track and found the ice covered waratah posts marking the route.

While approaching Bridge Peak, the clag was thickening and by the time I reached Kime Hut, the moon was barely penetrating through the clag. I stopped at Kime Hut for a brew, optimistically hoping the clag would clear, before ascending Mt Hector.

With the tap frozen I was boiling snow, which was relatively rapid as I was only cooking for one. In larger groups I have found this much more time consuming in the past. After drinking my tea, the clag was even thicker so it was to be here that I would hunker down for the night.

Wellington trampers often refer to Kime Hut affectionately as "The Fridge". Many claim it is warmer outside the hut than inside it.


Arriving here in the middle of the night, surrounded by snow and with myself as sole occupant it seemed a good time to test this theory. Keeping my Casio Protrek watch away from my own body heat so as to accurately use its thermometer function. It is not warm inside Kime Hut, however, it is about one degree warmer than outside.


Outside 2:30am: -0.8 C
Inside 2:40am: 0.4 C
Outside: 9:30am: 0.8 C
Inside: 9:40am: 1.6 C


When departing on Saturday morning, there was virtually no visibility so I was sure to take a compass bearing before heading back down to Otaki Forks. In fact, it was darker than much of the time I had traveled under the moon the night before.

While I did not get across the whole Southern Crossing as I intended, I sure had a great time in the snowy winter wonderland. Try again, during the full moon next month?
