Hi,

This track (https://www.openstreetmap.org/way/133648313) is rather long. Which part have you checked to be inexistent? Is the part to the east of the Ruisseau du Gravier (https://www.openstreetmap.org/way/1383640043) still present? Using Organic Maps, you can touch a point on the map, then click the 'share' button, and paste the link in this conversation if you wish to give me precise location information. Thanks in advance!
