I reached the way point 07-SURTH 1660 m with some orienteering difficulties due to very bad visibility mostly 10 - 20 m. I had to rely on my GPS and compass to find the correct directions. So I decided to cancel my activation today on Cret de la Neige. Further progress from 07-SURTH to F/JU-001 would have been very slow and perhaps risky. The weather now at Thoiry is very nice, but the summits on Jura above 1400 m seem to be still inside the same cloud.
