A second block of marble cut at a quarry near here has been deemed unsuitable to replace one cracked at the Tomb of the Unknown Soldier.
Rex Loesby of Sierra Minerals Corporation says the 55-ton block cut at the Yule Quarry last month looked good at first. But he says more research turned up small, dark gray spots that could be visible on the surface.
The monument at Arlington National Cemetery is made of marble cut from the Yule Quarry in 1931.
But two horizontal cracks in the tomb's walls first noticed in the 1940s have spread. Arlington officials asked Loesby last year to start looking for new marble.
A block cut last summer was also unsuitable.
Loesby says his crew will begin looking for marble directly below where the original stone was found.
