Wind-carved rock

  • Exhibition Text

    • This ventifact, or wind-carved rock, from the Dry Valleys of Antarctica demonstrates how rocks can be shaped and eroded into sculpture-like forms by erosion and weathering. The primary erosion comes from wind abrasion. Chemical weathering, expansion due to heating, and contraction due to cooling also contribute.
