The Ingala Valley (Russian: Ингальская долина) is an archaeological district in the area between the Tobol and Iset rivers.

In 1669, the governor of the Tobolsk rank [Wikidata] Petr Ivanovich Godunov told tsar Alexei Mikhailovich that gold, silver items and utensils were extracted from "Tatar graves" near the Iset River.

[5][11] The first among scientists to get acquainted with findings of the Ingala Valley was Daniel Messerschmidt, whose expedition into the Siberia Governorate took place in 1719-1727.

Gerhard Müller, who visited Siberia in 1733-1743 together with the Great Northern Expedition, stated that bugrovschiki activity was finished because the kurgans had been totally robbed.

In 1861, Nikolay Abramov (scientist) [Wikidata] published information about kurgans and hill forts of the Yalutorovsky, Tyumensky and Kurgansky Okrugs.

By analogy with other Mesolithic parkings [Wikidata] in the south of the Tyumen Oblast ("Katenka" and "Zvezdniy"), a chronological framework of the oldest finds in the valley was limited within 8th–7th millennium BC.

[19] The Neolithic presents with 37 sites found during excavations of the settlement "Dvuhozernoe-I", the ritual complex "Ostrov-II", and the grave field "Old-Lybaevo-IV".

The most prominent artifact of the grave field "Buzan-III" is the remains of a wooden funerary ladya [Wikidata] longer than 5 m found in 1996, the oldest in Northern Eurasia.

Eugene Volkov calls this phase the Dvuhozerny period of the Lybaevo culture (represented by artifacts of the settlements "Dvuhozernoe-I", "Lower Ingalinskoe-IIIa", "Ostrov-IIa" and "Upper Ingalsky Borok-II").

But finds in the settlement "Uk-III" near Zavodoukovsk and in the Khripunova grave field near village Krasnogorskoe discovered at the end of the 20th century forced more serious consideration of the presence of Andronovo culture in the Ingala Valley.

Of these there were found in the Ingala Valley monuments of the middle (the Khripunova grave field is the most northern of the Alakul cemeteries,[29] the settlement "Lower Ingalinskoe-III") and late (the second group of burials of the Khripunova grave field, the settlement "Uk-III") stages of dating the second quarter of the 18th – middle 16th century BC.

During the late Bronze Age construction of hill forts began in the Ingala Valley, the earliest of which is the Ak-Pash-I.

[31] The tallest of hill forts is the Lizunovo (Krasnogorskoe) in the Iset District; it is located on a promontory with a steep slope nearly 45 meters high.

The number of kurgans reaches 177, a diameter of individual ones more than 60 m.[34] Many kurgans contain highly artistic artifacts made of gold, silver, gemstones and numerous decorations made in workshops of Ancient Egypt, slave-owning states of the Northern Black Sea Coast [Wikidata] and Central Asia.

[24] So, during excavations of the Tyutrinsky grave field near the village Suerka in 1981, Natalya and Alexander Matveevs found beads from blue spinel, which is produced only in Hindustan, Sri Lanka and Borneo, and also a miniature (less than 2 cm in length) faience amulet of Harpocrates (Hellenistic tradition of an image of the Ancient Egyptian god Horus).

[36] A Sargat village discovered in the tract Copper Borok covers an area of 15.5 ha, which makes it considered a town.

A list of the objects of cultural heritage of federal importance in the Ingala Valley include: There are the archaeological school camp "Issedon" in the Isetsky District and "Lukomorye" in Zavodoukovsk.

[26][41] It was announced that in 2013 the "Ingala" sanatorium complex in the Zavodoukovsky District would be put into operation (land area of 13 ha, number of rooms 350 seats), being built to replace the "Niva" resort[42] (not opened yet as of 2014).
