We will present HST Pa-alpha observations of the Galactic center HII region G0.18-0.04, also known as the Sickle. Previous Spitzer IRAC observations determined that the Sickle is comprised of fingers of dust and gas which are strong analogs of the well known photoevaporated pillars in M16. The new observations enable us to further compare and contrast the Sickle pillars with those from M16 and other regions with similar features. In addition, we will use the Pa alpha data to search for evidence of ongoing star formation in the Sickle, and test whether triggered star formation in the Galactic Center is occurring at this location. The region inclusive of the Sickle contains some of the most unusual features in the Galactic Center, and the new observations support the idea that this site may be unique within the inner 200 pc. We will examine the correlation of the massive star population, the ionized gas, the PAH emission, warm dust and the non-thermal emission within this enigmatic region.
