I saw a youtube video of some strange and obviously artificial thing in the centre of the Greenland Icecap (centred at 70 degrees 34 minutes north and 40 degrees west). I went to Google Earth and took a close look at it. The object is about 50 miles long, dead straight, orange and yellow colouring, and looks like the leading edge of a vast object buried by snow and ice. The body of the object shows up for a considerable distance away to the south and west of the straight line, fading down into the snow as if it is buried at an angle. I was at an eye-altitude of 81 km, and the object took up my entire screen. The eastern edge of the object is at 38-56 W and 70-24 N, while the western edge is at 41.00 W and 70-43 N. Go and have a look on Google Earth, and I'd like some theories as to what the heck it is.
