It extends over the upper valleys of the Rion, Ingur and Tskhenis-tskhali, and is included in the modern government of Kutais.
The chief rivers are the Rion, which enters the Black Sea at Poti; the Chorokh, which enters the same sea at Batum; and the Ingur, the Kodor and the Bzyb, also flowing into the Black Sea in Abkhasia.
Besides the Bokovoi Khrebet several other short subsidiary ranges branch off from the main range at acute angles, lifting up high montane glens between them; for instance, the two ranges in Svanetia, which divide, the one the river (glen) Ingur from the river (glen) Tskhenis-Tskhali, and the other the river (glen) TskhenisTskhali from the rivers (glens) Lechkhum and Racha.Down all these glens glacier streams descend, until they find an opportunity to pierce through the flanking ranges, which they do in deep and picturesque gorges, and then race down the northern slopes of the mountains to enter the Terek or the Kuban, or down the southern versant to join the Rion or the Kura.
In the Laila, and limiting the great parallel basins of the Rion, Ingur and Skenis Shari [= Tskhenis-Tskhali] ..."
The most frequented pass in Svanetia is that of Latpari (9260 ft.), situated in the first of the southern subsidiary ranges mentioned above, and thus connecting the valley of the Ingur with the valley of theTskhenis-Tskhali.
Arid upland plains and parched hillsides take the place of the rich verdure and luxuriant arborescent growth of Imeretia, Svanetia and Mingrelia, the districts which occupy the valleys of the Ingur and Rion and the tributaries of the latter.
The Ingur, TskhenisTskhali, Rion and its tributaries (e.g.th.e Kvirila) are longer, but also in part torrential; they drain the great glacier region between Elbruz and Kasbek.
