Ignatievka Cave
[5] Although some sources associate the paintings to the Upper Paleolithic,[5][6] the age of the drawings continues to be debated.The radiocarbon dating of the charcoal drawings has resulted in more recent numbers, between 6,000 and 8,000 years ago.Ignateva Cave can be freely visited although it is best to travel via the small village of Serpiyevka [ru], which is off the main road past Sim, Chelyabinsk Oblast, heading eastwards, about 15 km (9.3 mi).The cave mouth is about 18 m (59 ft) above the small river backwater and reached by a metal ladder.Part of the inner cave can only be reached by crawling through a very narrow space about 0.5 m (1.6 ft) in height but this provides views of some of the better red ochre markings.
