The base of the Grand Canyon requires ten energy to complete, and from there, you'll need to collect various kinds of stone as the item's building materials.
- 8 Hermit Shale
- 8 Redwall Stone
- 8 Sandstone
- 8 Angel Shale
- 8 Kaibab Stone
Building the Grand Canyon is necessary to complete the "Yes We Can!" goal, which also asks you to collect from five Passenger Planes at your city's airport, and collect from eight different Cruise Ships, regardless of their destinations. For completing this particular goal, you'll receive five energy and 50,000 coins as your prizes.
It's interesting that this particular "Wonder" has been given such a light celebration in the game, as others (like the Egyptian Pyramids) were much more complex ordeals to complete. That being said, I definitely appreciate the break in the difficulty level, don't you?
Will you build a Grand Canyon in your CityVille town, or are you working on completing other existing Wonders in the game first? Let us know in the comments.
