I got some pics of where I went down .... you'll see how loose a surface it is but knowing this is exactly what I don't brake or turn hard into and only approach at a slow speed. The only thing I did notice was some slight drops and I wonder if the tyre was half way up one of those which started the movement to drop to the bottom and it just kept going ... that's just me trying to 2nd guess it though.









Looking back the other way towards the direction I'd come from.
