Pass Ratings, QR Codes, and Rules and Regs for hiking in the Berg

Theuns van Rensburg [L] and the cartographer discussing the first draft of "Noord Drakensberg North" with Natal officials at the Cathedral Peak Forestry Office, 1980

RATING THE BERG PASSES

There has been a fair consensus amongst map contributors that some sort of rating system should be applied to the escarpment passes, especially considering that these maps will not only be used by experienced hikers. Such ratings are always going to be subjective and we could all argue until the cows come home about this pass vs that, etc etc. Right at the start of the process I found the Vertical Endeavour ratings, and there are three reasons why I have more-or-less stuck with these:

1. They are not DANGER ratings, they are DIFFICULTY ratings. We have other symbols for danger, impassability etc. These VE ratings relate to length, steepness, bushiness, stoniness – all the factors that require specific kinds of fitness rather than sheer climbing competence and ability to deal with vertical rock faces or height exposure. Hence a really long arduous route that requires a whole day’s very steep slog up a broken stony route with lots of snaggy bush, little water and exposure to the hot afternoon sun might rate much higher than a route with one short C pitch in the middle, or higher than one that has a fairly easy ascent but a really dangerous descent IF you don’t turn out of the gully at the right point.

2. They are ratings for AVERAGE CONDITIONS. You can’t rate for every single kind of weather, temperature, ice or lightning danger, etc etc. In ‘Dragon’s Wrath’ Pearse says that ‘it would be a sad day if the Drakensberg were ever made totally safe’ – and the same surely applies to every wild place on Earth, and our apparently inborn need for the challenges of danger and excitement in our lives.

3. I found that three people involved with the original VE ratings had signed up for our mapping group, so what was more logical than to ask them to look at their ratings critically, and add passes that had not previously been rated by them? They are all highly experienced and I have no reason - including from my own now admittedly ancient experience - to doubt them.

Consequently the ratings have been updated with more precision in the later drafts, and stand for now with these words added to the map reference:

“Difficulty rating for Escarpment passes [where 10 is the extreme, requiring great experience and fitness]. Ratings according to Vertical Endeavour, under average conditions of weather and temperature. NB These are subjective DIFFICULTY ratings from experience, relating to the distance, altitude and steepness, state of path or substrate, need to bushwhack, scramble, etc etc; they do not indicate DANGER levels.”

I hope that we can all accept that there are issues in this process of mapping that we won’t all reach consensus on - otherwise the maps will never be made.

 


QR CODES

It's our intention to include a set of QR codes on the maps that link to relevant and informative websites. There are any number of free QR scanner-aps available for smart phones and they are a wonderful way of making the maps interactive and a rich resource in themselves. If you have a QR scanner on your phone scan the above and you'll see what we mean. We have room on the map for 20 codes and we have chosen those shown below. If you would like to suggest any others please contact us. NB if the codes below won't scan because they too close together block those you don't want with a bit of paper. If you click on the pic it will enlarge.


"RULES AND REGULATIONS" HIKING TIPS, SAFETY HINTS ETC.

We've published these as a separate Page [click here] -- if you would like to comment please feel free to do so. These are basically the same as published on the existing EKZNW maps but cleaned up with duplications omitted, etc etc.

All the best!

Map Drafts available for Download

Ezemvelo KwaZulu-Natal Wildlife, with whom we’ve been discussing the new map series since 2019, can’t meet on making inputs into the drafts of the first two maps until near the end of April. The delay is unfortunate but I have put a lot of thought into how we can move this process along as speedily as practicable, bearing in mind the extreme need for revised maps. With this in mind I have prepared two special maps for their meeting, which anyone interested may access and comment on at the link below.

I have taken the existing EKZNW maps and first aligned  them accurately upon the official 1:50 000 topo maps [SG or Surveyor General maps]. In this regard they match with some precision, regarding contours, rivers, etc but not paths or roads. Apparently the topographic info on these is based on the same projection as the SG maps but the paths etc are not, being based on the Cape Datum instead. This curious mixture of two systems is unprecedented and has led to many problems, not least of which is  that many paths appear in effect about 150 metres+ east and south of where they actually are, without any reference to the hills, cliffs, gullies and river beds around them. As you know there are no long/lat coordinates given for features on these maps and because of the above it would be impossible to provide them.

To illustrate this I have overlayed in purple the path and roads system as it appears on the drafts of the new maps. This ‘purple’ layer has been geo-referenced and is 100% based on actual gps readings in the field and/or interpolated with information from the SG maps, Google Earth and other photo sources, and inasmuch as it is subject to the same errors as any human-generated information I am satisfied that it is 99.5% as accurate as I can make it given the limitations of scale.

I have then added question marks where problems arise. Red question marks refer to paths and roads shown on the EKZNW maps that cannot be found and are not explained by the datum shift outlined above. Orange question marks refer to paths shown by EKZNW as ‘Minor Paths’ but which have been recently reported only as ‘ways to go’ –  nor can any trace of them be found on photos. A few purple question marks refer to paths found in the Cathedral Peak research area which do not appear on the EKZNW maps and where I don’t know if they are included in the public MTB system, or should be excluded.

Your comments on any of this would be welcome, the DropBox link is at https://www.dropbox.com/s/ujnj2fmpx22n25d/Compare%20Paths%20Maps%201and%202.zip?dl=0

 MAP 1 SIDE TWO DRAFT ready for comment!


The draft of MAP 1 SIDE TWO is ready for comment at last! Compilation has taken a little longer than expected, but it seems possible that the Cathedral Peak - Monk’s Cowl - Injisuthi area is one of the more complex parts of the Berg path system.

We have several queries and your inputs will be very gratefully received [and acknowledged!]. Preferably append them in ‘Comments’ below, or private message me at this address

CLOSING DATE: Sorry to rush you. April 25th is the deadline for comments - we want to go to print in early May!

Please refer to the 'Progress so far' page [see link on right] for most REFERENCE items; below the map extracts is a panel of most of the additional symbols we have added for the Side Two map.


1. Sphinx – see map extract below. There are two different peaks labelled Sphinx on different maps, flanking the summit of the Tlhanyaku Pass. Which one is correct? [and not to be confused with the Sphinx near Monk's Cowl campsite]


2. Cataract Valley [at Injisuthi]. As above, maps differ. Which is correct?


3. Dingaan’s Cave [just north of the Champagne Castle Hotel]. Not vital info for Berg hikers, but it falls on the map so we’d rather we had it right. Is it on the banks of the Sterkspruit, or does it look out over the Mankulumani?


4. Ladder Cave near Rainbow Gorge - does it exist? Is this where it is, near the Chockstone? How many does it accommodate?


5. Reido Cave, on the escarpment near Pampiring - how many can sleep in it?


6. Are you an MTB enthusiast? The jeep tracks off Mike’s Pass are used for MTB riding - have we got the grid right?


7. Quad biking near the Cathedral Peak hotel - is this for real?


There's a new page that you can access from the column on the right, dealing with the GOOD NEWS -- that we're printing on all-waterproof paper again!

NEW REFERENCE ITEMS

As we progress southwards on the maps we come across features that have not been encountered before, and these often require new map symbols. The panel below illustrates the new symbols added to the Reference in map 2.


Looking forward to your comments!
