It’s been a couple of weeks since we stopped by the WTC site. The most striking aspect from the street remains the speed with which glass surfaces begin to rise. It seems like only yesterday that three stories of glass wrapped around Tower One. Now with ten stories completed, the quartz-like surfaces start to take shape. At the Memorial Museum, Snohetta’s glass has flown up in what seems a matter of days. The facade already reflects the grove, whose trees continue their own march toward West Street.
