Abstract: A power ice screw system including an ice screw and screw adapter configured to engage the ice screw, thus enabling use of a power drill to install the ice screw in an ice feature, is described. The ice screw includes a drive head configured to engage the screw adapter. The screw adapter includes clearing ports that enable the adapter to expel ice that enters the adapter from within the ice screw hollow core. The ice screw core extends through the drive head to permit ice to flow through the ice screw and into the adapter. A cutting member resides within the screw adapter, typically disposed between two clearing ports. The cutting member can be flanked by two flanges configured to direct ice that has been disrupted by the cutting member outwardly through the clearing ports. The power drill is typically a lightweight battery powered electric drill.
