This signpost is near to the saddle between Maglić and Trnovaćki Durmitor.
The 2.8 km and 1:15 must be referring to Maglić, which is where I've just come from.
My next goal is Trnovaćko jezero, 2.6 km away and just over 600 m lower. I don't believe that I'll need the 2:00 hours that the sign says; I think that would be a normal time to climb this route, not to descend it.
Coordinates by approximation.
