Vihren in the context of "Musala"

A ridge is a long, narrow, elevated geomorphologic landform, structural feature, or a combination of both separated from the surrounding terrain by steep sides. The sides of a ridge slope away from a narrow top, the crest or ridgecrest, with the terrain dropping down on either side. The crest, if narrow, is also called a ridgeline. Limitations on the dimensions of a ridge are lacking. Its height above the surrounding terrain can vary from less than a meter to hundreds of meters. A ridge can be either depositional, erosional, tectonic, or a combination of these in origin and can consist of either bedrock, loose sediment, lava, or ice depending on its origin. A ridge can occur as either an isolated, independent feature or part of a larger geomorphological and/or structural feature. Frequently, a ridge can be further subdivided into smaller geomorphic or structural elements.

The Pirin Mountains (Bulgarian: Пирин [ˈpirin]) are a mountain range in southwestern Bulgaria, with the highest peak, Vihren, at an altitude of 2,914 m (9,560 ft).

The range extends about 80 km (50 mi) from the north-west to the south-east and is about 40 km (25 mi) wide, spanning a territory of 2,585 km (998 sq mi). To the north, Pirin is separated from Bulgaria's highest mountain range, the Rila Mountain, by the Predel saddle, while to the south it reaches the Slavyanka Mountain. To the west is located the valley of the river Struma and to the east the valley of the river Mesta separates it from the Rhodope Mountains. Pirin is dotted with more than a hundred glacial lakes and is also the home of Europe's southernmost glaciers, Snezhnika and Banski Suhodol.

Koncheto (Bulgarian: Кончето [ˈkɔnt͡ʃɛto], lit. 'foal') is a name given to a knife-edge ridge in the Pirin Mountains in Bulgaria, at an elevation of approximately 2,810 metres, between the peaks Banski Suhodol (2,884 meters) and Kutelo (2,908 metres). There are steep slopes on either side: the northwestern side is almost vertical and 300–400 metres deep, while the southwestern side is less steep (approximately 30 degrees) but deeper (800 metres). There is a steel cable stretched along the top of the ridge to help hikers across. It is said that some less experienced hikers go through Koncheto by saddling the ridge edge like a horse and slowly advancing, hence its name.

Kutelo (Bulgarian: Кутело [ˈkutɛɫo]) is a summit in the Pirin mountain range, southwestern Bulgaria. With a height of 2,908 m, it is the second highest peak in Pirin after Vihren (2,914 m), and the third one in Bulgaria, behind Musala (2,925 m) in Rila and Vihren. Kutelo is a double peak with a small saddle between the two parts, the lower being only one meter shorter than the higher one, at 2,907 m. Seen from the town of Bansko, it appears higher than Vihren.

Like Vihren, which towers to the south, Kutelo is built up of marble but its slopes though sheer are not so rocky and it is not very difficult to climb. On the north-eastern slopes there are alpine climbing tracks of category II "b". The Premkata saddle is situated to the south and leads to Vihren while to the north is the narrow karst edge Koncheto which links Kutelo to the summit of Banski Suhodol. There are no marked tracks to the summit of Kutelo, but on the slanting western slope among the rocks is nestled the track between the Vihren refuge and Yavorov refuge. This track also leads along Koncheto. In the homonymous waterless cirque to the north-east there are snow-drifts all the year. To the south-east is the cirque Golemiya Kazan with Europe's southernmost glacier, Snezhnika. Pirin's second glacierlet, Banski Suhodol Glacier, is situated below the northern face of Kutelo.

Snezhnika (Bulgarian: Снежника 'the snow patch') is a glacieret in the Pirin Mountains of Bulgaria, a remnant of the former Vihren Glacier. The glacieret lies at an elevation between 2,425 m (7,956 ft) and 2,480 m (8,140 ft) in the deep Golemiya Kazan cirque at the steep northern foot of Vihren (2,914 m (9,560 ft)), Pirin's highest summit. Due to the relatively easy access and its location along a popular hiking trail, Snezhnika is Bulgaria's most famous glacieret. Snezhnika has an average area of 0.01 km (0.0039 sq mi) and in 2006 it had a volume of 30,000 m (1,100,000 cu ft).

Snezhnika's size varies in length from 70 to 100 metres (west to east) and in width from 40 to 90 metres (north to south). Its firn is 8–11 m thick at the base and its snow cover, which is mostly fed by avalanche snow, can be as deep as 20 metres in March and April. Snezhnika's latitude of 41°46′09″ N makes it the southernmost glacial mass in Europe; the nearby Banski Suhodol Glacier below Koncheto, although larger, is slightly to the north.

Banski Suhodol (Bulgarian: Бански Суходол [ˈbanski suxoˈdɔɫ]) is a peak in the Pirin mountain, south-western Bulgaria. It is located in the northern part of Pirin on the main ridge. Its height is 2,884 m which ranks it in third place in Pirin after Vihren (2,914 m) and Kutelo (2,908 m).

To the south-east of Banski Suhodol on the main ridge is located at the summit of Kutelo and the two peaks are linked by the Koncheto ridge — a dizzy karst ridge which on some places is only 70 cm wide.

Pirin National Park (Bulgarian: Национален парк "Пирин"), originally named Vihren National Park, covering the larger part of the Pirin Mountains in southwestern Bulgaria, spanning an area of 403.56 square kilometers (155.82 sq mi).

It is one of the three national parks in the country, the others being Rila National Park and Central Balkan National Park. The park was established in 1962 and its territory was expanded several times since then. Pirin National Park was declared a UNESCO World Heritage Site in 1983. The elevation varies from 950 meters (3,120 ft) to 2,914 meters (9,560 ft) at Vihren, Bulgaria's second highest summit and the Balkans' third.
