Infirmary No. 2 of Sevpechlag (Pechzheldorlag) was organised at the Mishayag rail station in summer 1940. The total number of prisoners who died in the infirmary between 1940 and 1950 has not been established. Testimony by eyewitnesses, including staff from the infirmary, confirmed that there were mass burials near Mishayag.

In 1998-2003 the Pechora Memorial society and, in 1999, the town administration, carried out exploratory investigations: they studied the area, made test probes, questioned witnesses and drew up a plan of the burials. Three separate cemeteries were discovered where at various times Sevpechlag prisoners were buried: in 1940-1943, 1944-1945 and in 1946-1956. The first cemetery contained 350-400 common graves each containing 10-25 bodies. Stakes bearing the standing numbers had been partially preserved. There were also pits marked by two or more stakes; these presumably indicated repeated burials in the same pit. A compact burial of interned Polish army officers, temporarily held in Sevpechlag, was also discovered.

The second cemetery contains about 120 common graves and burial trenches which often cross one another. The third cemetery contains 7,500 individual graves and 22 large burials that may be common graves. Some of the graves from the 1950s are marked by crosses. In all three cases the boundaries of the burial area are not marked. In 2001 exploratory groups from Pechora and Syktyvkar together erected a commemorative wooden cross at the site; it has since become dilapidated and fell down. In 2012 a brigade of rail workers from Pechora put up a new cross of artificial stone.
