Kantega or also known as the Snow Saddle is located at a height of 22,000 feet in Himalayas, Nepal. Bing maps show this area in particular as pixilated while Google maps blacked it out. It is believed that Nazis made some secret explorations here an discovered a UFO base and their testing site. This area is famous for UFO sightings at large and maybe that is why this area has been blacked out so as to discourage its secret entrance to be discovered by the world.
6. Chukotka Autonomous Okrug, Siberia
Chukotka, located in the Russian Federal region has an area which belongs to the wilderness and it has been totally blurred out by the Google maps. A fake satellite image has been rather pasted over that region to make people think that is normal. This area is allegedly known to be a HAARP Russian site which is actually a facility for testing of ICBM or it may be a gold mine.
