We present Hubble Space Telescope ACS images of the Virgo cluster spiral galaxy NGC 4522, one of the nearest and clearest cases for ongoing ram pressure stripping of a galaxy's ISM by an interaction with the gas in the intracluster medium. The images show extraplanar star clusters which formed from stripped gas, large-scale dust lanes leaving the plane of the stellar disk, and small-scale head-tail dust features, which we propose are dense gas clouds being ablated by the ICM wind after the low density ISM has been stripped.
