Stairway to heaven
Decomposed-granite steps edged with concrete nudge this path upslope in a backyard in Portola Valley, California. Because
the steps taper from 8 feet wide at the bottom to 3 feet wide at the top, they appear to cover more ground than they do. (A
Cor-Ten steel wall enhances the effect; from a 4 1/2-foot base, it shrinks to 2 feet high at the top.) Dasylirion and dwarf lavender line the path.
