New results will be presented from an experimental capture system that achieves high resolution cryo-scanning electron microscopy images of natural cirrus particles. The novel system (Ice Cryo-Encapsulation by Balloon, "ICEBall") deploys a balloon-borne payload with environmental sensors and hermetically-sealed cryo-encapsulation cells.  The payload scoops particles from cirrus clouds, seals them, and returns them via parachute for vapor-locked transfer onto a cryo-scanning electron microscopy stage.  On several flights, including one highlighted here, thousands of cirrus particles were retrieved and imaged, revealing unanticipated particle morphologies and even greater complexity than expected
