The camp at the Obskaya rail station was set up in late 1946 as a sub-division of Sevzheldorlag, becoming the 5th division of Obsklag after 1947. A subdivision of Obsklag (Construction site 501), responsible for building the railroad from Chum to Labytnangi, was also based there. In 1948-1952 brigade 202 of Obsklag, a zone where women who had given birth in captivity and the camp children’s home (for those aged under 7), was deployed near the station.

In 1947-1950 prisoners, children from the home, and free workers were all buried in coffins in a cemetery half a kilometre away. The burials were made in shallow graves; stakes bearing numbers were placed on the graves and in some cases wooden crosses. The cemetery does not have a clearly defined boundary; the graves were made close together.

All the camp sub-divisions closed in 1955. More than 600 graves, 250 of them children’s graves, were uncovered as a result of investigation in the late 1990s. In 2000 after a low fire in the tundra the lids of the coffins caught fire and the burials were exposed. In 2001 an expedition of the Labytnangi branch of the Yamalo-Nenets local history society, led by A.N. Safonov, reburied the remains exposed by the fire in a common grave in the children’s section of the cemetery. In 2002 the area was fenced off and tidied; grave-markers were placed on the new common graves. A memorial cross was erected with the inscription, “Remember them in your Kingdom, O Lord. Here lie children, the victims of repression in the 1950s”.
