You Chose: Fix the Foundation.

Onward and Upward! It might take four years, but workers are sure they can successfully beef up the base of the Washington Monument without causing any damage to the rest of the structure. But to do it, they also suggest a change. To increase stability as well as to more closely resemble the dimensions of a historic Egyptian obelisk, the Army Corps of Engineers decides that the height of the monument should be ten times the width of the base. This means that that the Washington Monument will stand at 555 feet, not 600. It will still be the highest stone structure in the world!

To build upward, though, the workers need stone. Marble to be exact. You quickly discover that the quarry that supplied the stone for the original marble blocks from 1848 until 1854 is no longer available. That leaves you with two options. There is a quarry in Lee, Massachusetts that has marble available at a great price. But there's one problem: the color of the Massachusetts stone might not match the marble blocks already in place. Another option is a quarry just outside of Baltimore, Maryland. That's a lot closer to Washington, D.C., so it will be easier to transport. The Maryland stone may also be a closer color match, but it will be more expensive.

Which quarry will you choose to finish the Washington Monument?

Color change? No big deal

Massachusetts Marble

Using marble from Lee, Massachusetts will save money. The color change will probably not be noticeable--you hope.
