Natural Snow Depths

How much snow can I expect?
Recently I wrote up another description for an upcoming VCC trip and I was wondering how much snow can be expected. Since this is an existential question for all back country adventurers, I gathered some data and put it into the two graphs below. 

  • The green line shows you how much snow you can expect on average.
  • The blue and orange lines are the max and min extremes - there is quite a wide range!
  • And the red line shows you the percentage of bone dry seasons on that day.
The Buller graph gives you an idea for The Bluff, Westridge and the Howitt area while the Hotham graph is obviously for Bogong and Feathertop. E.g. my chance of running on grass around The Bluff on the 23rd September is 25% while if I'm lucky enough to find snow it might be around the 30cm mark.

You're welcome 😁

P.S.: Also keep in mind climate change is real and happening which means the red line goes up and the green line goes down. I know. It's sucks.

  1. Just thinking... Why did you choose the 1993 to 2016 year range ?
    As climate change is producing warmer winters in oz maybe data older than , say 15 years ago , shows a set of snow depth nos. that we will not likely experience again . Thus the 1993 to 2011 data are thus skewing the graphs - What does the 2001 to 2016 graph look like , very different ?

    1. That's the data which was available however I also looked and the graphs of only the last ten years and they're similar especially in regards of average snow depth and dry season percentage.
      The Australian winter climate is heavily influenced by the El Niño–Southern Oscillation (ENSO), Southern Annular Mode (SAM) and the Indian Ocean Dipole (IOD). If things fall in line - a neutral ENSO, negative SAM and negative IOD - we can still have bomber seasons. Unfortunately SAM and IOD are currently positive which basically means a cold and dry winter.

Garmin inReach Explorer+ Plus Review

A bit over a year ago Garmin acquired a company called DeLorme. Now if you have never heard of them, that isn't much of surprise since they their hardware portfolio is for a limited audience: Adventurers who leave the beaten path and stay away from the normal mobile phone grid territory. DeLorme also makes some map products but their main device is the inReach: A two-way satellite communicator using the iridium network with a 100% global coverage (For all Pauline Hanson / Trump fans: That's everywhere). Now these things aren't exactly cheap but given it isn't unusual in our household to spend a bit of extra money on weird hobbies (Anna: Dressage riding / Philipp: Geocaching) I get away with buying one of those.
The Predecessors In January Garmin announced the release of the third generation of the inReach - the SE+ and the Explorer+. The first generation was a little device which needed a smartphone as an interface and the second generation had already a colour displa…

A Magic Place in France

Have you ever heard of the Chartreuse Mountains? Yeah me neither. Although you really should have! It is literally one of those hidden gems on the planet. If you're into hiking, it's honestly rather difficult to have a bad time in the French Prealps or Alps. Seriously: Everything looks unbelievable cute, people are super-friendly and then of course there's that thing about french pastry, croissants, pain au chocolat, wine, cheese, ... It's fucking civilised!  
Did I mention that the landscape is also fairly stunning? Ooops sorry but you probably already looked at the picture. This is an arch called "La Tour Percée" and with 32m it's the biggest natural arch in the European Alps. If that's not enough, the sucker is also a double arch. I know it's a bit over the top but this is how it rolls. Why haven't I heard about this?!?Good question! Because you can't see that thing neither from the village below nor from the ridge-line above. It is obs…

Hiking Time Calculation

We all have been there. How long does it take me to get from A to B? In times of navigation systems and google maps that's easy to answer for most daily life applications. However when it's coming to hiking this gets a bit tricky.

There are a bunch of ways out there in order the calculate a hiking trip might take: AMC Book Time, SAC, Naismith's Rule, Swiss sign-posts and German sign-posts are all based on different formulas. You can find a couple of online tools which can calculate rough estimates for your hiking time, however they are always based on total distance and ascent. As soon as your hike goes up and down, you're stuffed.

Being a semi-nerd, I created a spreadsheet (instead of an app) which can calculate the hiking times based on the German Norm DIN 334466 sign-posts for trails. You only need to input a basic data-set which includes latitude, longitude and elevation per point. You can get that from recorded GPS tracks, GPS Visualizer or Garmin Basecamp. If yo…
