The lake is the fifth largest in Europe after Lake Ladoga and Lake Onega in Russia north of St. Petersburg, Lake Vänern in Sweden, and Lake Saimaa in Finland.

Lake Peipus is a remnant of a body of water which existed in this area during an Ice Age. It covers 3,555 km², and has an average depth of 7.1 m, the deepest point being 15 m. The lake has several islands and consists of 3 parts:

Chud

Chud or Chude (Old East Slavic: чудь, in Finnic languages: tshuudi, tšuudi, čuđit) is a term historically applied in the early Russian annals to several Finnic peoples in the area of what is now Estonia, Karelia and Northwestern Russia.

Perhaps the earliest written use of the term 'Chudes' to describe proto-Estonians was ca. 1100, by the monk Nestor, in the earliest Russian chronicles. According to Nestor, Yaroslav I the Wise invaded the country of the Chuds in 1030 and laid the foundations of Yuryev, (the historical Russian name of Tartu, Estonia). Then Chud was used to describe other Baltic Finns called volok which is thought to refer to the Karelians.

According to Old East Slavic chronicles the Chudes were one of the founders of the Rus' state.

The Northern Chudes were also a mythical people in folklore among Northern Russians and their neighbours. In Komi mythology, the Northern Chudes represent the mythic ancestors of the Komi people.

Etymology

There are a number of hypotheses as to the origin of the term. Chude could be derived from the Slavic word tjudjo ('foreign' or 'strange') which in turn is derived from the Gothic word meaning 'folk' (compare Teutonic). Another hypothesis is that the term was derived from a transformation of the Finno-Ugric name for the wood grouse. Yet another hypothesis contends that it is derived from the Sami word tshudde, meaning an enemy or adversary.

René Chudeau

René Chudeau (1864 - 1921) was a French geologist.

Formerly an instructor at the University of Besançon, from 1905 to 1914 he conducted a series of geological surveys in the Sahara (later day nations of Mali, Mauritania and Niger). His interests included Quaternary deposits, the formation of sand dunes, processes of aeolian erosion, et al. In the Taoudeni basin, he investigated ancient volcanoes, and south of Agadez, he found the presence of dinosaur bones. In the Zinder region, he made a discovery of Lower Cretaceous rocks being overlain by Upper Cretaceous successions. His geological collections are housed at the Muséum national d'histoire naturelle in Paris.

The botanical species Pennisetum chudeaui Trab. Maire is named in his honor.
