Beautiful beech and evergreen forests still cover large parts of the High Beskid. Above the tree-line(1200— 1300m) we meet for the first time with the characteristic plantformation of the Polonini (mountain pastures) which yield excellent pasturage for large and small cattle during the summer and create the foundation for a primitive dairy industry.
Along the southern foot of the High Beskid, and separated from it by a chain of longitudinal valleys, a long chain of mountains rises above the neighboring Hungarian plain, bearing the name of Vihorlat (the Burnt Out). The Rivers Uz (Ungh), Latorizia and Bershava, have cut the Vihorlat into four sections. The range is lower than the Beskyd, since it is less than 1100 m. high, but it is strongly cut up by deep-gorged valleys, and has steep,
rocky precipices, bold rocky summits and pretty little mountain lakes. The range, which is covered with thick oak forests, owes its scenic character to its geological composition. The Vyhorlat is a line of extinct volcanoes, in the old craters of which the mountain lakes of the region lie. The firm trachyte lava forms picturesque rock walls and peaks. East of the Verezki Pass begins a new mountain section, perhaps the most characteristic one in the sandstone Carpathians. It extends toward the east as far as the passes of the Prut and the Black Tyssa (Theiss) and the Yablonitza Pass. This part of the sandstone Carpathians bears the name of Gorgani.
The uniform mountain walls of the Beskid give way here to shorter mountain ridges, strongly cut up by cross valleys. The main streams of the northern slope, Opir, Limnitza — the two Bistritzas — flow thru deep, picturesque passes; still deeper are the valleys of the mountain streams which flow into the Theiss, as the Torez, Talabor, etc. It is a remarkable circumstance that the dividing border ridge is lower than the ridges facing it on the north and south, which are broken thru by magnificent passes.
The edge of the Gorgani ridge also shows traces of the old leveling-surface and has only small gorges, yet it is much more curled than in the Beskid. The ridge often becomes a sharp edge and the cone-shaped peaks further break its monotony. The height of the peaks is much greater than in the Beskyd. On the Galician side the Popadia attains a height of 1740 m.; Doboshanka, 1760 m.; Visoka, 1810 m.; Sivula, 1820 m.; in Hungarian territory the Stoh in the picturesque Bershavi group is 1680 m.; the Blisnitza, in the Svidovez Range, 1890 m., etc.
The ridges and peaks of the Gorgani are covered with seas of sandstone boulders and are, therefore, difficult of access. The light gray Yamna sandstone, of great resisting power, appears in this mountain section in very thick layers, and is the cause of the greater height and the bolder forms which, in places, are suggestive of high mountain ranges. The energetic weathering process, aided by the cover of winter snow, breaks up the mighty sandstone layers into great rocks, boulders, fragments and rubble. Deep fissures yawn between moss and lichencovered boulders, many boulders rock under the foot of the wanderer, and many of them, thru caving-in and thru accumulation, have formed natural chambers and hollows. The rocky ridges, covered with seas of boulders, are Arshizia, the Gorgan peaks, whence comes the name of the entire mountain range. The seas of boulders and rubblestone are called Zekit or Grekhit.
In the highest groups of the Gorgani Range (especially in the Svidovetz) are found also distinct traces of the glacial age, glacial excavations with small lakes or with swamps that have taken the place of lakes.
A splendid, only slightly thinned dress of virgin forest covers the Gorgani Chain. The lower forest section is composed of beech, ash and fir trees, the upper part of pines and stone-pines. The tree limit is very irregular and vascillates between 1100 and 1600 m. Mountain pastures are very rare, because of the seas of boulders and rubble-stone, but there are large and beautiful, tho not easily accessible, stocks of mountain pines.
