Jefferson Memorial

From National Mall and Memorial Parks:




Scaffolding is in place at the Jefferson Memorial as we get ready to test an experimental laser treatment on the biofilm that has blackened portions of the memorial in recent years, most notably the dome. Over the next month, we'll be treating 1,000 square feet of the dome to test the effectiveness of the technique. More at http://go.nps.gov/THJElaser.#HistoricPreservation #pewpew
