The range is composed of sandstones, siltstones and andesitic tuffs with granodiorite intrusions.<ref name="GSE"/>
==History== The Oloy Range was first mapped in the summer of 1870 by topographer P. Afonasiev who was part of the 1868 - 1870 East Siberia expedition of Baron Gerhard von Maydell (1835–1894) and astronomer Karl Karlovich Neyman (1830s–1887).<ref>{{Cite web |url=http://sibhistory.edu54.ru/%D0%9C%D0%90%D0%99%D0%94%D0%95%D0%9B%D0%AC_%D0%93%D0%B5%D1%80%D0%B3%D0%B0%D1%80%D0%B4_%D0%9B%D1%8E%D0%B4%D0%B2%D0%B8%D0%B3%D0%BE%D0%B2%D0%B8%D1%87 |title=Siberian History - МАЙДЕЛЬ Гергард Людвигович |access-date=2022-03-05 |archive-date=2022-02-26 |archive-url=https://web.archive.org/web/20220226051350/http://sibhistory.edu54.ru/%D0%9C%D0%90%D0%99%D0%94%D0%95%D0%9B%D0%AC_%D0%93%D0%B5%D1%80%D0%B3%D0%B0%D1%80%D0%B4_%D0%9B%D1%8E%D0%B4%D0%B2%D0%B8%D0%B3%D0%BE%D0%B2%D0%B8%D1%87 |url-status=dead }}</ref>
==Geography== The Oloy Range rises in the northernmost sector of the Kolyma Highlands System. The range runs in a roughly northwest / southeast direction for over {{convert|350|km|sp=us}}, between the Anyuy Range to the north and the Ush-Urekchen to the south, roughly parallel to both. The Omolon River marks its western limit, the Oloy river, a right tributary of the Omolon, limits it to the south. The Oloychan valley forms the northern boundary, while the eastern limit is not clearly delimited. The highest mountain of the range is a {{convert|1816|m|ft}} high peak located in the central part of the range,<ref name="STM"/><ref name=":0">{{Cite web |url=https://xn--80aaaa1bhnclcci1cl5c4ep.xn--p1ai/cd1/262-263.html |title=National Atlas of Russia - Chukotka |access-date=2022-03-05 |archive-date=2020-08-05 |archive-url=https://web.archive.org/web/20200805070739/https://xn--80aaaa1bhnclcci1cl5c4ep.xn--p1ai/cd1/262-263.html |url-status=dead }}</ref> not far to the west of {{convert|1301|m|ft}} high Gora Shebenochnaya.

Many rivers originate in the Oloy Range, including tributaries of the Omolon, such as the Oloychan, of the Bolshoy Anyuy, such as the Pezhenka (Пеженка), as well as of the Anadyr, such as the Yablon and the Yeropol which have their sources in the eastern area of range.<ref>1,000,000 scale Operational Navigation Chart; Sheet C-7</ref><ref name="GЕ">Google Earth</ref><ref name="STM"/>
==Flora== The slopes of the Oloy Mountains are largely bare and have a barren look, the only vegetation cover being mountain tundra. In certain locations there are thickets of dwarf Siberian pine. There is larch undergrowth along the valleys.<ref name="GSE"/>
