More Parkaeology

In April last year I speculated about the origin of an old track I found in the Mangatepopo Valley. That post included a map showing the Mangatepopo Hut on the other side of the valley from where it is today. I have since found a map from 1926 that both confirms the existence of the old hut site and confirms my speculation about a track from that hut.

The new (old) map from the New Zealand Department of Lands and Survey shows both the old hut site and the new hut site. A track is indeed indicated as originating at the old hut and heading east towards Ngaruhoe, and it is highly likely that this is the track that we found. Pukekaikiore is in approximately the same place as the (7) beside the old hut.

This map also shows a number of other interesting tracks. The track passing east from the new hut, through the (8), is the approximate location of the curent track through the valley, with the dog leg south being the old Devil's Staircase.

The track heading north from the new hut is also of considerable interest. That track also still exists, zig-zagging up the side of the valley and being clearly apparent when one is on the ridge. (See, for example, this post). The more easterly of the two branches seems to mirror the route taken when we dropped off Tongariro summit in June 2012 (see that post for a map of the route taken). The route on the 1926 map also seems to head over the top of North Crater before dropping down to the Ketetahi Hot Springs. This seems an obvious route when one looks at a topo map, but I have never tried it.

Finally, the more northerly route skirts around the side of Tongariro to go direct to the Ketetahi Hot Springs. It would be interesting to see whether any trace of that route remains.

Ngauruhoe Circumnavigation

The plan was simple: a loop around Ngauruhoe, constructed as follows:

• up the Mangatepopo Valley and up to South Crater by the standard track (no adventure here, although we could have done the old Devil's Staircase;
• across South Crater and drop down over the side into the Oturere Valley;
• cross-country to Oturere Hut;
• follow the Northern Circuit track south through the Rangipo Desert and turn west at an appropriate point;
• follow the gentle slope up between Ngauruhoe and the Tama Lakes - exact route not important because it's such a wide gentle lava flow;
• head over the saddle between Ngauruhoe and Hogsback / Pukekaikiore; and
• follow the unmarked but well-trod trail back to the Mangetepopo Valley track and back to the car.

down from South Crater, but it is by
ANY route.

Heading up to and across South Crater went like clockwork, and we made good time. Heather and Mike had a few misgivings on reaching the far rim of South Crater, but we were soon on our way down and the going was a lot easier than it first appeared. Some might even say it was fun!

After following the stream bed down for a while we branched across the sandy desert to meet up with the poled track to Oturere Hut. There was a bit of a hunt for the track, but the GPS waypoints turned out to be pretty much spot on.

Oturere Hut

After a stop at the hut to refuel we continued on, following the Northern Circuit track as planned. The track is undulating, but for the most part is runnable. We were still right on our planned time at this point, so all was good.

Time for a late lunch

Saddle #1

The plan was to cross the saddle between Ngauruhoe and Pukekaikiore. What I didn't realise was that there were three saddles! The first saddle is shown in the photos below. This didn't quite feel right, and after a bit of a diversion down the side of the valley we came back up and continued on to the next saddle.

It looks like a saddle... as a natural low point it even
has water lying on the ground. In fact it IS a saddle...
just not the one we were looking for.

Saddle #2 - The Crucial (Wrong) Turn

Having recovered from the previous wrong turn we continued gradually upwards. Cresting a slope to (another) saddle we were very pleased to find a marker pole. There were no orange marker triangles, but the existence of the pole meant we were heading in the right direction!

I stopped to take a couple of photos, and then we left turned and headed down... in the wrong direction. The photo below shows where we should have gone - across the lava field to the third and final saddle. Instead we headed around the slopes of Pukekaikiore. The only way out in that direction is an unpleasant and very slow stretch of bush-bashing, which is exactly what we had to do.

The Pole: this pole is crucial - at this point head
across the lava field, maintaining height. Do not be
tempted to head down.

The goal from the pole: head for the left hand side
of THIS saddle.

Having traversed around the side of Pukekaikiore until we could go no further, it was time to head down through the bush. Even though the day was hot, Heather and I stopped to put our overtrousers on to stop our legs being scratched to pieces. We pushed and shoved and slipped and slid through the thick scrub and bush. With a stroke of luck Mike happened on a narrow but deep stream bed, and that provided a clear path down.

Out of the bush and into a more open stream at the base of Pukekaikiore, we followed that UP for a short distance to a clearer section of vegetation that allowed us to gain the low hill between us and Mangatepopo Valley. At the top of the hill was an unmarked track. Following this west led us back to the poled Northern Circuit track (the section from The Chateau to Mangatepopo), and we were out!

A short diversion back to Mangatepopo Hut to sign out of the log book and then back to the cars. 10h47, but most likely would have been the planned 8h if we had taken the right route.
