A survey inspector climbs atop the 555-foot Washington Monument and secures safety lines on Tuesday Sept. 27. Several inspectors will rappel down the monument to inspect each stone, looking for damage caused by a Aug. 23, 5.8-magnitude earthquake which caused several stones to crack.

Wow. I really hope this guy is not scared of heights. Working at 555 feet in the air, I assume being comfortable with heights is a prerequisite for this job.

Incredible new images were released Monday showing what it was like inside the Washington Monument as an earthquake hit in late August. The monument has not re-opened since. NBC's Tom Costello reports.
