We found a new flying location! Locals refer to the mountain as Delphinus, and it towers visibly over the road between Ananuri and Pasanauri. Yesterday, we finally decided to take a look at it. Locals immediately told us that the mountain was accessible by road, up to the main ridge.
As it turns out, there is a ridge that is almost 2 km long, running roughly east to west. You can launch at multiple points along the ridge, although the best point probably is close to the peak, since it affords a flatter takeoff point, as well as the opportunity to launch when the wind comes more from the east. At 2150 m, it is higher than Tianeti, and also seems to offer better opportunities for cross-country flying.
Two flights there so far, September 4 & 5, 2010. One took me quite a way out west, but that's a different story. The second one, on a day with strong inversion, gave good lift along the ridge, although no thermals to be found further out.
Landing in the Valley is not a problem, although you need to watch for various powerlines. Also, some of the landing sites have plenty of rocks, and several have lots of sand, which your wing may not like too much. (Obviously, watch the valley winds!)
On balance, this appears like a major new opportunity for flying in Georgia, even if Google Earth decides to show it in the darkest of colors. It may offer very significant cross-country possibilities. Even just for soaring, it presents you with the sight of beautiful mountains, church ruins, Kazbegi in the distance, two lakes, and much more.
It's probably only suitable for advanced pilots, or intermediate pilots with detailed guidance. On a day with strong eastward wind, I reached climbing speeds of 6.9 m/s. The next day, with little wind from the east, I still had short surges of 5.9 m/s, as the thermals punch their way up along the hillside. Flying needs to be pretty active.
More information and nicer photography to follow! We will also try and find out more about the mountain's great name.
