Holy hell, that is an amazing piece of terrain! Grandmanner's Facebook page is full of purest terrain porn. Awesome stuff.
I was in Gallipoli 11 years ago, spring of 2000 on one of my backpacking trips around Europe. I was the only person in the minibus tour who didn't have an ANZAC accent - our Turkish guide had spent a year in Australia (working on a history degree) and had a pronounced Oz accent!
Gallipoli is either vertical or covered in thornbushes - sometimes both. I've seen a couple of sites on the Western Front too, but 70+ years of greenery softens them. Gallipoli really hasn't changed, these days it's mostly still raw rock, thornbushes, memorials and graveyards.
"Those heroes that shed their blood and lost their lives... You are now lying in the soil of a friendly country. Therefore rest in peace. There is no difference between the Johnnies and the Mehmets to us, where they lie side by side here in this country of ours... You, the mothers, who sent their sons from far away countries, wipe away your tears; Your sons are now lying in our bosom and are in peace. After having lost their lives on this land they have become our sons as well." - Atatürk
