Whispers of a Shifting Divide is a polished bronze sculpture that imagines the unimaginable. It was inspired by my children's 1997 discovery of a crustacean fossil lying in the desert of West Texas just before we moved east to semitropical Houston, Texas.

The sculpture symbolizes the U.S. 100th meridian, the demarcation between the arid western US and the humid eastern US since the early 1800s. Since 1980, this demarcation between arid and humid has shifted 140 miles eastward from the west side of Austin, Texas to the east side of Austin to the 98th meridian. Another 140 miles — another 40-50 years — and Houston, known for its semitropical humidity will be on the arid side of the boundary.

The polished bronze material nods to Houston's future and industrial character, particularly the polished steel street signs in its minimally landscaped commercial tourist area, Uptown Houston.

By imagining the unimaginable, this work fosters a dialogue that calls for environmental consciousness of the possibilities of our actions.
