The machined stainless-steel block that was embedded in the construction of the obelisk point. A second, identical block was embedded in the pyramidal point. The Cor-Ten side panels of the pyramid and obelisk points engaged, and were welded to, steps in the block, leaving only a small strip of stainless above and below the join-line exposed. Exposed stainless was textured and “seeded” with iron filings in order to stain the surface to match the surrounding weathered steel.
