We didn't end up going along Gendarme Ridge. The idea was going to be a half day trip from Philps Pk to White Needle and back. It was blowing a gale when we got to Philps Pk, so we decided to climb White Needle from Baron Pass on the way out. Then the weather turned a bit nasty. (Weather wasn't actually too bad, just enough to settle the dust on the Loddon Plains. Didn't bother putting the gaiters on for the whole week.)
Frenchmans Track has been massively upgraded since I was there about 20 years ago, though not much track work has been done on the plains. Only went a kilometre or so down the Irenabuss track - that's also been upgraded.
