Hi, Searching the Internet, I found that this landform has a number of names by which it is known. They include the “Eagle Nest,” “Patomsky Crater,” and “Patom Cone.” I like “Patom Cone” because it is nongeneric as to its origin.
I found one paper about the Patom Cone that argues it to be a "cryovolcano." This paper is: Alekseyev V.R., 2012. Cryovolcanism and the mystery of the Patom cone. Geodynamics & Tectonophysics. vol. 3, no. 3, pp. 289–307. doi:10.5800/GT-2012-3-3-0075. PDF file at http://popovgeo.professorjournal.ru/c/document_library/get_file?p_l_id=22997&folderId=69343&name=DLFE-36927.pdf and http://gt.crust.irk.ru/images/upload/tblarticle83/magazin83.pdf Abstract at http://gt.crust.irk.ru/article_83.html and http://gt.crust.irk.ru/magazin2012_3.en.html Unfortunately the main text is it Russian and My wife is to busy at work to translate it for me this week. As a result, I do not know the specifics of the arguments that this paper makes. An extended abstract about this landform is: Ermolin, E., O. Ingerov, and А.
