Oberrothorn

The Unterrothorn (or simply Rothorn) is a mountain of the Swiss Pennine Alps, overlooking Zermatt in the canton of Valais. It is located west of the Oberrothorn, on the range north of the Findel Glacier. The summit can be reached by cable car via Sunnegga and Blauherd. The Rothorn paradise is one of the main ski areas located around Zermatt.

The Bösentrift is a mountain of the Pennine Alps, overlooking Täsch and Zermatt in the canton of Valais. It lies north of the Oberrothorn.

The Gant-Hohtälli Aerial Tramway is a large-cab cable car near Zermatt, Switzerland. It is 2,707 metres (8,881 ft) long and spans an elevation of some 1,057 metres (3,468 ft). This cable car is notable in that it runs over the tallest aerial lift pylon in Switzerland, with a height of 94 metres (308 ft).

The Findel Glacier (German: Findelgletscher) is a valley glacier in the Monte Rosa massif east of Zermatt in the Pennine Alps. It has a length of 8 km (5.0 mi) and covers an area of 19 km2 (7.3 sq mi).The starting point of the Findel Glacier is on the Cima di Jazzi at 3,803 m (12,477 ft) above sea level, on the border between Switzerland and Italy. From there the glacier flows to the west between the Rimpfischhorn and Strahlhorn on the north and the Stockhorn on the south. The end of glacier tongue is located at 2,500 m (8,200 ft) above sea level. In October 2009, a group of Swiss scientists from the University of Zurich carried out an experiment to measure the length of the glacier, comparing their results with a previous experiment in 2005. Their results showed that the glacier had lost 49 million cubic metres of ice, and has lost a quarter of its surface area since 1850.

The Grünsee ("Green Lake") is a small lake near Zermatt, Switzerland, which is fed by the Findel Glacier. It is quite remote and is only accessible by foot, a small hub of the many footpaths in the area. There is a small hamlet nearby of the same name.

The Moosjisee (also Mossjesee, Mosjesee, Moosjesee) is a reservoir in the Findeltal valley above Zermatt in the Swiss canton of Valais. The lake is located at an elevation of 2,139 m (7,018 ft) slightly north of the Findelbach river. The reservoir is used for power generation and snowmaking. It is fed in part by the glacial milk of the Findel Glacier and therefore gets its characteristic milky turquoise color.

The Hohtälli is a mountain of the Swiss Pennine Alps, located southeast of Zermatt in the canton of Valais. It lies on the range that separates the Findel Glacier from the Gorner Glacier, between the Gornergrat and the Stockhorn. Its summit has an elevation of 3,275 metres (10,745 ft) and includes a cable car station. The Hohtälli is part of a ski area and features several ski runs leading down the mountain.

The Rote Nase (German for "Red Nose") is a mountain of the Swiss Pennine Alps, located east of the Gornergrat in Valais. The summit is 3,251 m (10,666 ft) above sea level. It is located to the Southeast of the town of Zermatt, and features several ungroomed ski runs leading down the mountain. The summit can be accessed using either a T-bar lift running up from lower down the mountain or a cable car running from Hohtälli.

The Weingartensee is a small lake located east of Täsch at the foot of the Alphubel, in the Swiss canton of Valais. The lake has a surface area of 0.64 ha and is located at 3,058 metres above sea level. It lies near the bottom of the Weingartengletscher glacier. Following the flood of June 2001, a dam was built and the water level was slightly reduced.

The Stockhorn (3,532 metres (11,588 ft)) is a mountain of the Swiss Pennine Alps, located to the southeast of the town of Zermatt. It lies on the range between the Findel and Gorner glaciers, east of the Gornergrat. The Stockhorn is part of the Zermatt ski area. A now-defunct cable car station at an altitude of 3,405 metres (11,171 ft) is located west of the summit; the original aerial tramway connecting the Gornergrat to the Stockhorn via Hohtälli was dismantled in 2007.

The Kölner Observatorium für SubMillimeter Astronomie (KOSMA) was a radio telescope for submillimeter astronomy located at 3,135 m (10,285 ft) on Gornergrat near Zermatt (Switzerland). It was operated by I. Physikalisches Institut, University of Cologne, and Radioastronomisches Institut, University of Bonn.The telescope had a primary diameter of 3 m (9.8 ft), and a secondary diameter of 0.27 metres (0.89 ft). It was equipped with heterodyne receivers covering 210 to 820 GHz, corresponding to wavelengths between 0.35 and 1.4 mm, for observations of lines from the interstellar medium.Because of the good climatic conditions at the altitude of 3135 m (10285 ft), astronomical observatories have been located in both towers of the Kulmhotel at Gornergrat since 1967. In 1985, the KOSMA telescope was installed in the southern tower by the Universität zu Köln and, in the course of 1995, replaced by a new dish and mount. In the northern tower, a 1.5 m infrared telescope was operated until 2005 by an Italian association of universities (TIRGO). In 2010, the telescope was moved to a site in Yangbajain in Damxung County in Tibet at an altitude of 4300m and renamed CCOSMA.

The Gornergrat (English: Gorner Ridge; 3,135 m (10,285 ft)) is a rocky ridge of the Pennine Alps, overlooking the Gorner Glacier south-east of Zermatt in Switzerland. It can be reached from Zermatt by the Gornergrat rack railway (GGB), the highest open-air railway in Europe. Between the Gornergrat railway station (3,090 m (10,140 ft)) and the summit is the Kulm Hotel (3,120 m (10,240 ft)). In the late 1960s two astronomical observatories were installed in the two towers of the Kulmhotel Gornergrat. The project “Stellarium Gornergrat” is hosted in the Gornergrat South Observatory.
