Ice Station Sabrina is the tenth episode of the fourth season and the eighty fifth overall episode of Sabrina the Teenage Witch.
When Harvey surprises Sabrina with a romantic weekend skiing in the mountains, she is less than thrilled at the prospect of being driven up to the cabin by Brad. After finding this out, Sabrina starts to panic and asks her aunts what she should do. Hilda and Zelda then decide that Salem should go with the kids so he can tell Sabrina if she could use her magic or not in front of Brad, making him less than thrilled at missing a Western movie marathon on television. However, things don't go as planned when Brad's witch hunting gene kicks in when Sabrina uses her magic to fix his heater. As a result, they get stuck in a snow bank on the side of the road.
Later, when Brad's father shows up at Hilda and Zelda's to find out about the kids, they decide to go and look for Sabrina, Harvey, and Brad with him. Unable to use their magic because they believe that he is also a witch hunter, Hilda and Zelda discover that he is only Brad's stepfather, allowing them to use magic around him to change the weather so that Sabrina is able to use magic to save them.
