Template:Short description Template:About Template:Infobox body of water
Lake Titicaca (Template:IPAc-en;<ref>Template:Dictionary.com</ref> Template:Langx {{#invoke:IPA|main}}; Template:Langx) is a large freshwater lake in the Andes mountains on the border of Bolivia and Peru. It is often called the highest navigable lake in the world. Titicaca is the largest lake in South America, both in terms of the volume of water and surface area.<ref name=strontium>Grove, M. J., P.

OverviewEdit
The lake is located at the northern end of the endorheic Altiplano basin high in the Andes on the border of Peru and Bolivia. The western part of the lake lies within the Puno Region of Peru, and the eastern side is located in the Bolivian La Paz Department.
The lake consists of two nearly separate subbasins connected by the Strait of Tiquina, which is Template:Cvt across at the narrowest point. The larger subbasin, Lago Grande (also called Lago Chucuito), has a mean depth of Template:Cvt and a maximum depth of Template:Cvt. The smaller subbasin, Wiñaymarka (also called Lago Pequeño, "little lake"), has an average depth of Template:Cvt and a maximum depth of Template:Cvt.<ref name="Dejoux">Dejoux, C. and A.

Since 2000, Lake Titicaca has experienced constantly receding water levels. Between April and November 2009 alone, the water level dropped by Template:Cvt, reaching the lowest level since 1949.

NameEdit
Given the various Indigenous groups that occupied the Lake Titicaca region, it likely lacked a single, commonly accepted name in prehistoric times and at the time the Spaniards arrived.<ref name="Standish2003a">Standish, C. (2005) Ancient Titicaca: The Evolution of Complex Society in Southern Peru and Northern Bolivia. Oakland, California, University of California Press. 338 pp. Template:ISBN</ref>
The terms titi and caca can be translated in several ways. In Aymara, titi can be translated as either puma, lead, or a heavy metal. The word caca (kaka) can be translated as white or grey hairs of the head and the term k’ak’a can be translated as either crack or fissure, or alternatively, comb of a bird.<ref name="Standish2003a" /> According to Weston La Barre, the Aymara considered in 1948 that the proper name of the lake is titiq’aq’a, which means gray, discolored, lead-colored puma. This phrase refers to the sacred carved rock found on the Isla del Sol.<ref name="La Barre1948a">La Barre, W. (1948) The Aymara Indians of the Lake Titicaca Plateau, Bolivia. American Anthropological Association Memoir. no. 68, pp. 208–210.</ref> In addition to names including the term titi and/or caca, Lake Titicaca was also known as Chuquivitu in the 16th century. This name can be loosely translated as lance point. This name survives in modern usage in which the large lake is occasionally referred to as Lago Chucuito.<ref name="Standish2003a" />
Stanish argues that the logical explanation for the origin of the name Titicaca is a corruption of the term thakhsi cala, which is the 15th- to the 16th-century name of the sacred rock on the Isla del Sol.<ref name="BauerOthers2001a">Bauer, B., and Stanish, C. (2001) Ritual and Pilgrimage in the Ancient Andes. Austin, Texas, University of Texas Press. 314 pp. Template:ISBN</ref> Given the lack of a common name for Lake Titicaca in the 16th century, the Spaniards are thought to have used the name of the site of the most important indigenous shrine in the region, thakhsi cala on the Isla del Sol, as the name for the lake. In time and with usage, this name developed into Titicaca.<ref name="Standish2003a" />
Locally, the lake goes by several names. The southeast quarter of the lake is separate from the main body (connected only by the Strait of Tiquina) and the Bolivians call it Lago Huiñaymarca (also Wiñay Marka, which in Aymara means the Eternal City) and the larger part Lago Chucuito. The large lake also is occasionally referred to as Lago Mayor, and the small lake as Lago Menor.<ref name="Standish2003a" /> In Peru, these smaller and larger parts are referred to as Lago Pequeño and Lago Grande, respectively.<ref name="Dejoux" />
Highest lakeEdit
With a surface area of Template:Cvt and an elevation of Template:Cvt, Lake Titicaca is often called the highest navigable lake in the world. That claim is generally considered to refer to commercial craft. Numerous smaller lakes around the world are at higher elevations,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> such as the Template:Convert crater lake of Ojos del Salado, which at an elevation of Template:Convert is the overall highest lake in the world, and the Template:Cvt Lake Puma Yumco, which at an elevation of Template:Convert is the highest large lake in the world. For many years, the largest vessel afloat on Lake Titicaca was the 2,200-ton (2,425 U.S. tons), Template:Cvt SS Ollanta. Today, the largest vessel is most likely the similarly sized train barge/float Manco Capac, operated by PeruRail.
TemperatureEdit
The cold sources and winds over the lake give it an average surface temperature of Template:Cvt. In the winter (June – September), mixing occurs with the deeper waters, which are always between Template:Cvt.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
EcologyEdit
Lake Titicaca is home to more than 530 aquatic species.<ref name="Kroll">Kroll; Hershler; Albrecht; Terrazas; Apaza; Fuentealba; Wolff; and Wilke (2012).

The lake holds large populations of water birds and was designated as a Ramsar Site on August 26, 1998. It has also been designated an Important Bird Area (IBA), in both Bolivia and Peru, by BirdLife International because it supports significant populations of many bird species.<ref name=bli>{{#invoke:citation/CS1|citation

GeologyEdit
Template:Further The Tinajani Basin, in which Lake Titicaca lies, is an intermontane basin. This basin is a pull-apart basin created by strike-slip movement along regional faults starting in the late Oligocene and ending in the late Miocene. The initial development of the Tinajani Basin is indicated by volcanic rocks, which accumulated between 27 and 20 million years ago within this basin. They lie upon an angular unconformity which cuts across pre-basin strata. Lacustrine sediments of the Lower Tinajani Formation, which are exposed within the Tinajani Basin, demonstrate the presence of a pre-Quaternary, ancestral Lake Titicaca within it between 18 and 14 million years ago (Mya).<ref name="MaroccoOther1995a">Marocco, R., R.

This core contains a continuous record of lake sedimentation and paleoenvironmental conditions for Lake Titicaca back to about 370,000 BP. For this period of time, Lake Titicaca was typically fresher and had higher lake levels during periods of expanded regional glaciation that corresponded to global glacial periods.

Lacustrine sediments and associated terraces provide evidence for the past existence of five major prehistoric lakes that occupied the Tinajani Basin during the Pliocene and Pleistocene. Within the northern Altiplano (Tinajani Basin), these prehistoric lakes were Lake Mataro at an elevation of Template:Cvt, Lake Cabana at an elevation of Template:Cvt, Lake Ballivián at an elevation of Template:Cvt, Lake (North) Minchin at an elevation of Template:Cvt, and Lake (North) Tauca at an elevation Template:Cvt. The age of Lake Mataro is uncertain—it may date back to the Late Pliocene. Lake Cabana possibly dates to the Middle Pleistocene. Lake Ballivián existed between 120,000 and 98,000 BP. Two high lake stands, between 72,000 and 68,000 BP and 44,000–34,000 BP, have been discerned for Lake Minchin within the Altiplano. Another ancient lake in the area is Ouki. The high lake levels of Lake Tauca have been dated as having occurred between 18,100 and 14,100 BP.<ref name="Clapperton1993a">Clapperton, C.

ClimateEdit
Lake Titicaca has a borderline subtropical highland/alpine climate with cool to cold temperatures for most of the year. The average annual precipitation is 610 mm (24 in) mostly falling in summer thunderstorms. Winters are dry with very cold nights and mornings and warm afternoons. Below are the average temperatures of the town of Juliaca, in the northern part of the lake.
IslandsEdit
UrosEdit
The "Floating Islands" are small, human-made islands constructed by the Uros (or Uru) people from layers of cut totora, a thick, buoyant sedge that grows abundantly in the shallows of Lake Titicaca.<ref name=slate>Template:Cite journal</ref> The Uros harvest the sedges that naturally grow on the lake's banks to make the islands by continuously adding sedges to the surface.
According to legend, the Uru people originated in the Amazon and migrated to the area of Lake Titicaca in the pre-Columbian era, where they were oppressed by the local population and were unable to secure land of their own.<ref name=slate/> They built the sedge islands, which could be moved into deep water or to different parts of the lake, as necessary, for greater safety from their hostile neighbors on land.
Golden in color, many of the islands measure about Template:Cvt, and the largest are roughly half the size of a football field.<ref name=slate/><ref name=natgeo>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Each island contains several thatched houses, typically belonging to members of a single extended family.<ref name=slate/> Some of the islands have watchtowers and other buildings, also constructed of sedges.
Historically, most of the Uros islands were located near the middle of the lake, about Template:Cvt from the shore; however, in 1986, after a major storm devastated the islands, many Uros rebuilt closer to shore.<ref name=slate/> Template:As of, about 1,200 Uros lived on an archipelago of 60 artificial islands,<ref name=slate/> clustering in the western corner of the lake near Puno, Titicaca's major Peruvian port town.<ref name=natgeo/> The islands have become one of Peru's tourist attractions, allowing the Uros to supplement their hunting and fishing by conveying visitors to the islands by motorboat and selling handicrafts.<ref name=slate/><ref name=natgeo/>
AmantaniEdit
Amantani is another small island on Lake Titicaca populated by Quechua speakers. About 4,000 people live in 10 communities on the roughly circular Template:Cvt island. Two mountain peaks, called Pachatata (Father Earth) and Pachamama (Mother Earth) and ancient ruins are on the top of both peaks. The hillsides that rise up from the lake are terraced and planted with wheat, potatoes, and vegetables. Most of the small fields are worked by hand. Long stone fences divide the fields, and cattle and sheep graze on the hillsides.
No cars and no hotels are on the island. Since machines are not allowed on the island, all agriculture is done by hand. A few small stores sell basic goods, and a health clinic and six schools are found. Electricity was produced by a generator and provided limited power a few hours each day, but with the rising price of petroleum, they no longer use the generator. Most families use candles or flashlights powered by batteries or hand cranks. Small solar panels have recently been installed on some homes.
Some of the families on Amantani open their homes to tourists for overnight stays and provide cooked meals, arranged through tour guides. The families who do so are required to have a special room set aside for the tourists and must conform to a code specified by the tourist companies that help them. Guests typically take food staples (cooking oil, rice, etc., but no sugar products, as they have no dental facilities) as a gift, or school supplies for the children on the island. The islanders hold nightly traditional dance shows for the tourists, where they offer to dress them up in their traditional clothes and allow them to participate.
TaquileEdit
Taquile is a hilly island located Template:Cvt east of Puno. It is narrow and long and was used as a prison during the Spanish Colony and into the 20th century. In 1970, it became property of the Taquile people, who have inhabited the island since then. The current population is around 2,200. The island is Template:Cvt in size (maximum measurements), with an area of Template:Cvt. The highest point of the island is Template:Cvt above sea level, and the main village is at Template:Cvt. Pre-Inca ruins are found on the highest part of the island, and agricultural terraces on hillsides. From the hillsides of Taquile, one has a view of the tops of Bolivian mountains. The inhabitants, known as Taquileños, are southern Quechua speakers.
Taquile is especially known for its handicraft tradition, which is regarded as being of the highest quality. "Taquile and Its Textile Art" were honored by being proclaimed "Masterpieces of the Oral and Intangible Heritage of Humanity" by UNESCO. Knitting is exclusively performed by males, starting at age eight. The women exclusively make yarn and weave.
Taquileans are also known for having created an innovative, community-controlled tourism model, offering home stays, transportation, and restaurants to tourists. Ever since tourism started coming to Taquile in the 1970s, the Taquileños have slowly lost control over the mass day-tourism operated by non-Taquileans. They have thus developed alternative tourism models, including lodging for groups, cultural activities, and local guides who have completed a 2-year training program. The local Travel Agency, Munay Taquile, has been established to regain control over tourism.
The people in Taquile run their society based on community collectivism and on the Inca moral code ama sua, ama llulla, ama qhilla, (do not steal, do not lie, do not be lazy). The island is divided into six sectors or suyus for crop rotation purposes. The economy is based on fishing, terraced farming based on potato cultivation, and tourist-generated income from the roughly 40,000 tourists who visit each year.
Isla del SolEdit
Situated on the Bolivian side of the lake with regular boat links to the town of Copacabana, Bolivia, Isla del Sol ("Island of the Sun") is one of the largest islands of the lake. Geographically, the terrain is harsh; it is a rocky, hilly island. No motor vehicles or paved roads are on the island. The main economic activity of the approximately 800 families on the island is farming, with fishing and tourism augmenting the subsistence economy.
Over 180 ruins remain on the island. Most of these date to the Inca period around the 15th century AD. Many hills on the island contain terraces, which adapt steep and rocky terrain to agriculture. Among the ruins on the island are the Sacred Rock, a labyrinth-like building called Chinkana, Kasa Pata, and Pilco Kaima. In the religion of the Incas, the sun god was believed to have been born here.Template:Citation needed
During 1987–92, Johan Reinhard directed underwater archaeological investigations off of the Island of the Sun, recovering Inca and Tiahuanaco offerings. These artifacts are currently on display in the site museum of the village of Challapampa.<ref>Reinhard, Johan (1992) "Underwater Archaeological Research in Lake Titicaca, Bolivia." In Ancient America: Contributions to New World Archaeology, N. Saunders (ed.), Oxford: Oxbow Books, pp. 117–143.</ref>
Isla de la LunaEdit
Isla de la Luna is situated east from the bigger Isla del Sol. Both islands belong to the La Paz Department of Bolivia. According to legends that refer to Inca mythology Isla de la Luna (Spanish for "island of the moon") is where Viracocha commanded the rising of the moon. Ruins of a supposed Inca nunnery (Mamakuna) occupy the eastern shore.<ref>Bolivia, Lonely Planet 2007, Template:ISBN</ref>
Archaeological excavations<ref>Bauer, Brian and Charles Stanish 2001 Ritual and Pilgrimage in the Ancient Andes University of Texas press, Austin</ref> indicate that the Tiwanaku peoples (around 650–1000 AD) built a major temple on the Island of the Moon. Pottery vessels of local dignitaries dating from this period have been excavated on islands in Lake Titicaca. Two of them were found in the 19th century and are now in the British Museum in London.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The structures seen on the island today were built by the Inca (circa 1450–1532) directly over the earlier Tiwanaku ones.
SurikiEdit
Suriki lies in the Bolivian part of lake Titicaca (in the southeastern part also known as lake Wiñaymarka).<ref name="footprint">Template:Cite book</ref>
Suriki is thought to be the last place where the art of reed boat construction survives, at least as late as 1998. Craftsmen from Suriqui helped Thor Heyerdahl in the construction of several of his projects, such as the reed boats Ra II and Tigris, and a balloon gondola.<ref name="footprint" />
TransportEdit

HistoryEdit
The lake has had a number of steamships, each of which was built in the United Kingdom in "knock down" form with bolts and nuts, disassembled into many hundreds of pieces, transported to the lake, and then riveted together and launched.
In 1862 Thames Ironworks on the River Thames built the iron-hulled sister ships SS Yavari and SS Yapura under contract to the James Watt Foundry of Birmingham.<ref name=YavariStory>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The ships were designed as combined cargo, passenger, and gunboats for the Peruvian Navy.<ref name=YavariStory/> After several years' delay in delivery from the Pacific coast to the lake, Yavari was launched in 1870 and Yapura in 1873.<ref name=YavariStory/> Yavari was Template:Cvt long, but in 1914 her hull was lengthened for extra cargo capacity and she was re-engined as a motor vessel.<ref name=YavariStory/>
In November 1883, during the final phase of the War of the Pacific, the Chilean military command sent the Template:Ship to the lake, via railroad, from Mollendo to Puno to control the area.<ref>Template:Cite book</ref><ref>Template:Cite book</ref> It was the first warship to navigate the lake.<ref>Template:Cite journal</ref>
In 1892, William Denny and Brothers at Dumbarton on the River Clyde in Scotland built Template:SS.<ref name=Clyde>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> She was Template:Cvt long and was launched on the lake in 1893.<ref name=Clyde/>
In 1905, Earle's Shipbuilding at Kingston upon Hull on the Humber built Template:SS.<ref name=YavariSteamers>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name=Cruise>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> By then, a railway served the lake, so the ship was delivered in kit form by rail.<ref name=Cruise/> At Template:Cvt long and 1,809 tons (1,994 U.S. tons), Inca was the lake's largest ship thus far.<ref name=Cruise/> In the 1920s, Earle's supplied a new bottom for the ship, which also was delivered in kit form.<ref name=Cruise/>
Trade continued to grow, so in 1930, Earle's built Template:SS.<ref name=YavariSteamers/><ref name=Cruise/> Her parts were landed at the Pacific Ocean port of Mollendo and brought by rail to the lake port of Puno.<ref name=Cruise/> At Template:Cvt long and 2,200 tons (425 U.S. tons), she was considerably larger than the Inca, so first a new slipway had to be built to build her.<ref name=Cruise/> She was launched in November 1931.<ref name=Cruise/>
In 1975, Yavari and Yapura were returned to the Peruvian Navy, which converted Yapura into a hospital ship and renamed her BAP Puno.<ref name=YavariStory/> The Navy discarded Yavari, but in 1987, charitable interests bought her and started restoring her.<ref name=YavariStory/> She is now moored at Puno Bay and provides static tourist accommodation while her restoration continues.<ref name=YavariStory/> Coya was beached in 1984, but restored as a floating restaurant in 2001.<ref name=YavariSteamers/> Inca survived until 1994, when she was broken up.<ref name=YavariSteamers/> Ollanta is no longer in scheduled service, but PeruRail has been leasing her for tourist charter operations.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
