tectonic fractures : gondwanaland dispersal

Gondwana Circle Competition, Botanical Garden, San Francisco—5th place, Honorable Mention

*with Rene Davids,  FAIA, Principal, Davids Killory Architects*

During the dispersal of the Gondwana supercontinent, rocks fractured through columnar jointing.  In columnar jointing, rock cools rapidly forming tessellated, hexagonal shrinkage cracks and columns.  This proposal processes the five stages of the dispersion of Gondwana through columnar jointing to create a field of prismatic modules.  The topography is a place to inhabit—the landscape can be used for education, stormwater management, rest, reading, play, and even a small amphitheater.

All of the modules are tinted, pre-cast, fly-ash concrete, sixteen inches in diameter.  Rebar and concrete fixitive stabilizes chains of modules.  Their heights range from four to twenty-one inches, in five dispersal stages.  Four other specialized modules relate world geography: the tall mountains with canted, engraved surfaces; planted ones are wooded and riparian vegetation; voids for sand are arid regions; resin modules with LEDs are water bodies.  Gaps in the field of modules drain stormwater from the sloping paths.  The planting strategy includes lichens and sedges—lichens are the first plants to emerge after major geological disturbances.  For educative purposes, perimeter signage, engraved fossils, and text imprinting describe the geologic and horticultural history of Gondwana and introduce the surrounding collections in the Botanical Garden.
