Avatech Awareness Day with the BMG

18th Jan 2016by rosshewittguiding1 Comment

In the lead up to Christmas I was lucky enough to get invited to an Avatech training and awareness day offered to the British Mountain Guides. Avatech rep Craig Widdicombe who happens to be my neighbour, hence the invite, ran the course. For those of you who have not yet seen the Avatech system, its a smart probe that gives you a snow profile in under 30 seconds. Compared to a manual pit which could take 30 minutes! The probe has a pressure sensor built into the tip that records the different resistances offered by the layers in the snow.

We started off in the classroom with a run through the application, its layout, how snowprofile data and associated observations / photographs are input and how to find historical data for your chosen route or ski area. Data from the probe is transmitted by Bluetooth to the app on your smart phone where it is uploaded to Avatech’s site. The interface is really user friendly and intuitive so its pretty easy to find your way around. It also incorporates a map system which can be used for your route planning.

The system has already become popular amongst the professionals in north America where it is hailed as a game changer. Meteo France and the Italian avalanche forecasters have also invested in a number of probes. A probe costs around 1800 Euros so its a significant investment but you can subscribe to have access to the website on an annual basis. The real benefit is if these become the industry standard and a number of snow profiles are performed on a particular slope of pitch giving subscribers a good overall picture of the stability on that particular slope.

Preseason Powder Hunting

With the first snowfall of the season kicking things off in mid November its been a crazy busy period searching for powder stashes. The stable snow conditions have allowed me to go and explore some new areas and revisit some that were long forgotten years ago. The biggest challenge has been finding motivated partners and I’ve already racked up 50K vertical touring metres this autumn and 162 ski days for the year. Luckily I have a few trusted partners available on different days so I’m not always on my own. The highlight was finding 3 couloirs that don’t feature in any of my guidebooks which were filled with primo pow. I’ve also spotted a couple of cool lines which should be good to go once we get some more snow.

First Turns of the Seaon

As the autumnal days shorten and the shadows grow across the valley, I realise how important it is for me to visit these high sun-drenched places. Its had been over 2 months since I visited the Midi and on return its beauty stunned me. Couple that with the fun of sliding downhill on a pair of skis and its obvious why its he best ski lift in the world aka ‘The Mothership’. Our first turns of the 15/16 season as Tom Grant and myself get training and acclimatising for our New Zealand ski trip next week.

Brevent Rock Climbing – Premier Corvee and Ex Libris

2 days of very contrasting weather in; the first uber hot and sunny with Davide de Masi on Premier Corvee, the second misty, damp and cold with James Clapinski wrapped up in all the clothes we had. Both were fun in their own ways. Both fun routes worth doing.

Bonne Etique – Trident

A fine day out with my buddy Davide de Masi on impeccable granite cracks last month. Definitely some of the best rock I’ve been on in the massif and I’m inspired to go back and climb the ‘Untouchables’ pitch next year when I am rock fit.
