What is a primary function of an avalanche probe?

The primary function of an avalanche probe is to pinpoint the location of an avalanche victim. This specialized tool is designed to be extended into the snow to search for a buried individual. When someone is caught in an avalanche, the snow can quickly bury them several feet deep. The use of a probe allows rescuers to determine the precise location of the victim by feeling for a body under the layer of snow. By systematically probing the snow with this long, typically telescoping pole, searchers can effectively locate and subsequently dig out the victim more quickly and efficiently.

The other choices do not accurately represent the main purpose of an avalanche probe. While it may aid in other activities related to avalanche survival and rescue, such as marking spots or supporting gear in certain scenarios, these are not its primary roles. Its sole and critical function during avalanche rescues is to aid in quickly identifying where to dig, making a significant difference in response time and potentially saving lives.
