What kind of accretion is this ?
Is it some extreme landscape formed by the timeless accumulation of rocky fragments through some extreme geological process?
Are these bazaar looking canyons, seldom seen landforms of some far away country?
Were they created through years and years of erosion?
Or is this laminated landscape some fantasy realm in a science fiction movie that takes place in another galaxy.
No. It is the real handiwork of conceptual artist Tara Donovan who has glued and stacked thousands and thousands of styrene index cards to create the ten looming towers that can be viewed at the Smithsonian American Art Museum, Renwick Gallery in Washington DC.
