Although there are rugged terrain and high points in the central uplands, the first major mountain range inland from the Adriatic is an area of predominantly serpentine rock. The serpentine zone extends nearly the length of the country, from the North Albanian Alps to the Greek border south of Korce, an area 10 to 20 miles wide and over 125 miles in length lying generally between the central uplands and the eastern highlands. At Elbasan, however, it makes nearly direct contact with the coastal plain, and it reaches the eastern border for nearly 50 miles in, and north of, the lake region. Within its zone there are many areas in which sharp limestone and sandstone outcroppings predominate over the serpentine, although the ranges as a whole are characterized by rounded mountain features.
The serpentine rock derives its name from its dull green color and often mottled or spotted appearance. It can occur in several states. Iron, nickel, or other metals can substitute in its chemical formula for the more prevalent magnesium and will cause color variations.
The mountains east of the serpentine zone are the highest in the country and are the basis for part of the eastern boundary. They occupy a narrow strip south of Lakes Ohrid and Prespa, and a similar one, also running north and south, lies between the White Drin River and the Yugoslav city of Debar. A peak in the Korab range, on the border north of Debar, exceeds 9,000 feet. The ranges have north-south trend lines. Geologically young and composed largely of hard limestone rocks, the eastern highlands, together with the North Albanian Alps and the serpentine zone, are the most rugged and inaccessible of any terrain on the Balkan Peninsula.
Lake Region
The three lakes of easternmost Albania are part of the Macedonian lake district. The Yugoslav border passes through Lake Ohrid; all but a small tip of Little Lake Prespa is in Greece; and the point at which the boundaries of all three states meet is in Lake Prespa. The two larger lakes have areas of about 100 square miles each, and Little Lake Prespa is about one-fifth as large. These are total surface areas, including the portions on both sides of the national boundary lines. The surface elevation is about 2,285 feet for Lake Ohrid and about 2,800 feet for the other two. The lakes are remote and picturesque. Lake Ohrid is fed primarily from underground springs and is blue and very clear. At times its transparency can approach 70 feet. A good percentage of the terrain in the vicinity of the lakes is not overly steep, and it supports a larger population than any other inland portion of the country.
NATIONAL BOUNDARIES
The distinct ethnic character of the people and their isolation within a fairly restricted and definable area brought support for their demands for independence in the early twentieth century. There were places where different ethnic populations intermingled, and there were other pressures that affected the definition of the borders. The Kosovo area across the northeastern border is a part of modern Yugoslavia, but it contains a substantial Albanian population. There are Greeks and Albanians in the mountains on both sides of the southeastern boundary. Albania is not content with the Kosovo situation, and neither Greece nor Albania is satisfied with the division effected by their mutual border.
The country is the smallest in Eastern Europe and has a perimeter of only 750 miles. The border shared with Yugoslavia runs northward from Lake Prespa, around northern Albania, to the Adriatic Sea for a total of just under 300 miles. Forty miles of this border follows river courses, and an almost equal distance is within lakes. The Greek border from the common point in Lake Prespa southwest to the Ionian Sea is about 160 miles long. Twelve miles of this border are within lakes but, because it crosses the trend lines of the southern mountain ranges, only four miles are along rivers.
The Adriatic and Ionian coastline is just under 300 miles long. The lowlands of the west face the Adriatic Sea and the Strait of Otranto, which is a mere 47 miles from the heel of the Italian boot. The Albanian Riviera, the coastline that runs southeast from Vlore, is on the Ionian Sea.
