Now if you go on Google Earth and go to the location of the Obruchev Hills...

66°34'59.88"S 99°46'0.12"E

you will find that the range of hills are at the same location as the supposed 'Hollow Earth Entrances'

Thread: Hollow Earth; Antarctic entrance

2 entrances, located at

66°36'12.74"S 99°43'12.35"E
66°33'11.58"S 99°50'24.02"E

The Russians named the hills after Vladimir Obruchev, I guess out of respect and the fact the author had died, but is there more to this than meets the eye? It's certainly a strange coincidence, if indeed it is that.
