heres the coordinates photo from satelite view. lots of melts in this area with this effect. though here it dousnt look like a door quite as much....just a melt... this thing is huge in size, ill post a photo of it compared to the showa station that is just due north of here. the station is about 5000 feet north.
Some posted pics only show you a glimpse or at different angles to give that 'look' of something else. But hey, you never know. It may be one of the tunnels from Inner Earth Lizard speak, here we come!
