Broken Obelisk: A Conservation Case Study
Extensive pitting at the top of Broken Obelisk in 2004. The pitting was caused by expandable foam that was sprayed into the top of the obelisk during conservation treatment in the 1980s, and the unintended result was that the interior walls of the obelisk were continually exposed to moisture. The metal in this section needed to be replaced. Photo: Laramie Hickey-Friedman, The Menil Collection.
