dec 17, 1000000 - Glass decomposed, hard granite eroded, Great Pyramid of Giza unrecognizeable, Footstep on Moon eroded

Description:

Current glass objects in the environment will be decomposed.
Various public monuments composed of hard granite will have eroded one meter, in a moderate climate, assuming a rate of 1 Bubnoff unit (1 mm / 1,000 years, or ~1 inch / 10,000 years).
Without maintenance, the Great Pyramid of Giza will erode into unrecognizability.
On the Moon, Neil Armstrong's "one small step" footprint at Tranquility Base will erode by this time, along with those left by all twelve Apollo moonwalkers, due to the accumulated effects of space weathering.(Normal erosion processes active on Earth are not present due to the Moon's almost complete lack of atmosphere.)
