Using Local Material

I love the red rock of the Zion and Bryce National Parks, and its permutations of yellow or white, depending on which mineral leached into the porous sandstone over the millennium. I also love seeing how the Parks and the local communities work these local building materials into the landscape and garden design.

blends with the surrounding landscape.

We saw many examples of this in both Parks. The roads in the park are colored red (very useful for determining when you are in or out of the park); and red rock is worked into the landscape as rocks, bricks, drainage ditches, retaining walls, and bench supports. I have seen this done well in other regions as well. In Alaska, folks use slate and granite; in the San Francisco Bay Area we use volcanic rock; in Spokane, they use basalt columns and polished river rocks.

The rocks and bricks come from a small local quarry, providing employment and building materials with a sense of place.
