Lovely Summer Weather or LSW!


I'm due to go on a 5-6 Day tramp over Harper's Pass starting on Monday next, this track is highly weather dependant as you need to cross three major rivers on the first two days. So I thought I'd have quick look at the extended forecast......

Ha!!!!!..... Good one Jon......

Man can I pick them.....!

Next week kiddies we have a cold front coming up from the South, and if than wasn't enough we also have not one but two Tropical Cyclones heading towards New Zealand.

Here is the extended weather for next week in the Harper's Pass/Lake Sumner Region:

Saturday: Cloudy with showers
Sunday:  Showers with cloud
Monday: Rain, cloudy periods (Day i would need to cross the Otira, Otehake and Taramakau rivers)
Tuesday:  More of the same.... (at least 3-4 crossings of the Taramakau and some sizable side streams)
Wednesday: ....ditto
Thursday: Heavy rain, high winds possible
Friday: Yep, you got it, more of the same.....
Saturday: Sigh........
Sunday: Why even bother asking........!

Here are a couple of weather predictions from the Met Service and Metvuw:

Metvuw weather prediction, Cyclone to East of NZ

In a prediction for later that same day you can clearly see the second cyclone closing on the country from the west.

MetVuw weather prdiction for next week




You have a good look at that Met Service weather map, it looks like some crazed, weather god descending to smite us....!
It reminds me of those wacked out drawings in my copy of Fear and Loathing in Las Vegas.

As the old timers used to say "...Huey will be chucking it down..."

PS: I had an alternate plan to tramp from Windy Point to the NZDA hut near the Nina River. Obviously if there is torrential rain and high wind you dont want to be walking over three high 
saddles (one is 1700m ASL) which you need to on that trip.
.
My alternate alternate plan is to scrub the Harpers Pass trip altogether and go walk the Queen Charlotte Walkway in early March as both are sections of the Te Araroa Trail I havent walked yet. 

I'm organising this now....

Otira Valley Track: Arthurs Pass N P: 30th January

On my way back from my recon of the Otira river I took the opportunity to go for a walk up the Otira Valley. The Otira Valley track can be located just over Arthur's Pass on the West Coast side of the mountains. The track goes up valley to the Northern face of Mt Rolleston and is an easy and very beautiful walk of about 2-2.5 hours duration.

The track can usually be walked in all seasons but there is extreme avalanche danger over Winter and Spring as there are high, steep mountains on both sides of the valley. The track is easy but if you are heading up here in Winter/Spring you need to know what you are doing.

About 5 minutes up the track you can follow a side track to Lake Misery, a medium sized tarn on the saddle at the Pass. It is a 20 minute walk and there is a boardwalk and interpretive panels with interesting information about the area.

I visited it when I walked the Arthurs Pass Walking Track in 2015.

Yes...they are not kidding!

There are great views across the to the North West side of SH73. You can see Temple Basin skifield, one of the last club skifields in a NZ National Park. It is organised, maintained and for the use of the Club which owns the infrastructure. There is a fine access track to the ski lodge which makes a good day walk.

I thought the flowers below were Mt Cook Lillies but have been informed that they are in fact
Common Mountain Lilly, Celmisia semicordata which are endemic to the Otira Valley. There are certainly a lot of them growing in this area.

You cross a number of small side streams on the track, they do not pose a problem under normal conditions but could flood if there was a lot of rain.

There is a foot bridge about an hour up valley, this is the end of the track and the start of the marked mountaineering route to the upper valley. You are relatively safe up to this point, past the bridge is the start of the rock/snow fall area. It is not surprising they have avalanches with the massive cliffs which loom over the track on both sides of the valley. 

You should not go past the bridge in Winter/Spring without some knowledge of avalanche conditions as avalanches are a regular occurrence over those seasons.

Who wants to be squashed by a couple of thousand tonnes of rock and snow? Not me!

Footbridge over the Otira River
 The bridge over the upper Otira River gets washed away about every 2-3 years and needs to be replaced, when you get a good old Nor' Wester blowing you can get massive amounts of rainfall over a short time span.

Flood city!

 After crossing the bridge I continued another 2 km's up the valley before turning back. If you keep walking you eventually reach a mountain cirque just below the rocky Northern Face of Mt Rolleston. 
I've visited the area before so didn't feel the need to go any further up the valley.

I headed back down to the bridge and stopped for a late lunch before starting back to the trail head.

 Mt Rolleston at the head of the valley is not your classic pyramid shaped peak but rather one of the more common extended high ridges we have in New Zealand.. There are three significant peaks for alpine trampers & climbers to aspire to.

 It can be climbed from the northern side but the common route is up the Crow Face which is on the southern, more gentle side of the mountain.

 It's difficult to see in this photo but all of those rocks have fist sized chunks of Pounamu (Greenstone/Jade) embedded in them. Pounamu has always been favoured by the Maori for decorative weapons and ornaments. This whole area is rich in Pounamu deposits but it is a National Park so they cannot be taken.

It is awesome to see them in their natural setting.

This is a very nice day walk, slightly more adventurous than some in the area but certainly not outside most peoples abilities. You could certainly camp in the upper reaches of the valley and in fact I saw a party of three heading up valley for that reason. Just be careful in Winter/Spring because of the avalanche risk.
