A mountain pass is a navigable route through a mountain range or over a ridge . Since mountain ranges can present formidable barriers to travel, passes have played a key role in trade, war, and both human and animal migration throughout history. At lower elevations it may be called a hill pass . A mountain pass is typically formed between two volcanic peaks or created by erosion from water or wind.
33-672: Fall River Pass (elevation 11,796 feet (3,595 m)) is a mountain pass in northern Colorado , in the Rocky Mountains of the western United States . It is located in the Front Range , within Rocky Mountain National Park . The pass is traversed by U.S. Highway 34 on Trail Ridge Road between Granby and Estes Park . However, as at Milner Pass on the Continental Divide , the road does not descend after reaching
66-403: A gap , saddle , col or notch . A topographic saddle is analogous to the mathematical concept of a saddle surface , with a saddle point marking the minimum high point between two valleys and the lowest point along a ridge. On a topographic map , passes can be identified by contour lines with an hourglass shape, which indicates a low spot between two higher points. In the high mountains,
99-508: A certain Chunradus Prenner de Mittenwalde is mentioned in 1299. The German word Prenner probably refers to somebody who uses slash-and-burn techniques for land clearing. A name for the pass itself appears for the first time in 1328 as ob dem Prenner (German for above the Prenner ). The Romans regularised the mountain pass at Brenner, which had already been under frequent use during
132-600: A connection of the name Brenner with the ancient tribe of the Breuni or the Gaulish chieftain Brennus , but since the pass name appears for the first time only in the 14th century, a more recent etymology is far more likely. Prenner was originally the name of a nearby farm, which itself was named after its former owner. The farm of a certain Prennerius is mentioned in documents in 1288,
165-502: A difference of 2,000 meters (6,600 ft) between the summit and the mountain is defined as a mountain pass. Passes are often found just above the source of a river , constituting a drainage divide . A pass may be very short, consisting of steep slopes to the top of the pass, or a valley many kilometers long, whose highest point might only be identifiable by surveying . Roads and railways have long been built through passes. Some high and rugged passes may have tunnels bored underneath
198-518: A nearby mountainside, as with the Eisenhower Tunnel bypassing Loveland Pass in the Rockies, to allow faster traffic flow throughout the year. The top of a pass is frequently the only flat ground in the area, and may be a high vantage point. In some cases this makes it a preferred site for buildings. If a national border follows the ridge of a mountain range, a pass over the mountains is typically on
231-578: A result, air and noise pollution have generated heavy debate in regional and European politics. As of 2004 , about 1.8 million trucks crossed the Europa Bridge per year. In order to ease the road traffic, there are plans to upgrade the Brenner Railway from Verona to Innsbruck with a series of tunnels, including the Brenner Base Tunnel underneath Brenner. While the official groundbreaking of

The central section of the Brenner Pass covers a four-lane motorway and railway tracks connecting Bozen/Bolzano in the south and Innsbruck to the north. The village of Brenner consists of an outlet shopping centre (supermarkets and stores), fruit stores, restaurants, cafés, hotels and a gas station. It has a population of 400 to 600 (as of 2011 ). Older, obsolete theories suggested

There are thousands of named passes around the world, some of which are well-known, such as the Khyber Pass close to the present-day Afghanistan-Pakistan border on the ancient Silk Road , the Great St. Bernard Pass at 2,473 metres (8,114 ft) in the Alps , the Chang La at 5,360 metres (17,590 ft), the Khardung La at 5,359 metres (17,582 ft) in Ladakh , India and
330-416: Is a site where bungee-jumping from the bridge has become a popular tourist attraction. The ever-increasing freight and leisure traffic, however, has been causing long traffic jams at busy times even without border enforcements. The Brenner Pass is the only major mountain pass within the area; other nearby alternatives are footpaths across higher mountains at an altitude of above 2,000 metres (6,600 feet). As
363-846: Is also used, particularly in Europe. In the highest mountain range in the world, the Himalayas, passes are denoted by the suffix "La" in Tibetan, Ladhakhi, and several other regional languages. Examples are the Taglang La at 5,328 m (17,480 ft) on the Leh-Manali highway , and the Sia La at 5,589 m (18,337 ft) in the Eastern Karakoram range. Scotland has the Gaelic term bealach (anglicised "balloch"), while Wales has

Dairy cattle graze in alpine pastures throughout the summer in valleys beneath the pass and on the mountain slopes. At lower altitudes, farmers log pine trees, plant crops and harvest hay for winter fodder. Many of the high pastures are at an altitude of over 1,500 metres (4,900 feet);
429-747: Is the Brenner pass in the Alps . Some mountain passes above the tree line have problems with snow drift in the winter. This might be alleviated by building the road a few meters above the ground, which will make snow blow off the road. There are many words for pass in the English-speaking world. In the United States, pass is very common in the West , the word gap is common in the southern Appalachians , notch in parts of New England , and saddle in northern Idaho .

For instance, Argentina and Chile share the world's third-longest international border , 5,300 kilometres (3,300 mi) long, which runs north–south along the Andes mountains and includes 42 mountain passes. On a road over a pass, it is customary to have a small roadside sign giving the name of

Completion of the railway enabled the Austrians to move their troops more efficiently; the Austrians had hoped to secure their territories of Venetia and Lombardy (south of the Alps), but lost them to Italy following the Second Italian War of Independence in 1859 and Austro-Prussian War in 1866.

891-479: The pass and its elevation above mean sea level . Apart from offering relatively easy travel between valleys, passes also provide a route between two mountain tops with a minimum of descent. As a result, it is common for tracks to meet at a pass; this often makes them convenient routes even when travelling between a summit and the valley floor. Passes traditionally were places for trade routes, communications, cultural exchange, military expeditions etc. A typical example
924-483: The pass from the west, but instead continues to climb along a side ridge; thus, neither pass is the high point on Trail Ridge Road, which crests at 12,183 feet (3,713 m) elevation, east of Fall River Pass, still within Rocky Mountain National Park. On the other hand, the old, largely unpaved, and one-way-uphill Fall River Road (see adjoining map) does have its summit at Fall River Pass, where it joins
957-555: The prehistoric eras since the most recent Ice Age. The Brenner Pass, however, was not the first trans-Alpine Roman road to become regularised under the Roman Empire.
