In wilderness search operations, what tracking techniques may be employed?

Ground tracking, scent tracking, and aerial surveillance are all essential techniques utilized in wilderness search operations.

Ground tracking involves observing physical signs left by a person in the wilderness, such as footprints or disturbances in the environment. This technique allows search teams to follow the likely path of a missing individual and gain valuable insight into their movements.

Scent tracking, often facilitated by specially trained search dogs, leverages the animal's keen sense of smell to locate a person. This method is particularly effective in wilderness settings, where a human scent may linger in an area despite environmental factors.

Aerial surveillance incorporates the use of helicopters, drones, and other aircraft to cover larger areas quickly. This technique is advantageous for spotting individuals from above, especially in terrain that might be difficult to navigate on foot.

Combining these methods enhances the overall effectiveness of search efforts, enabling teams to maximize their resources and improve their chances of locating a missing person efficiently. Other options listed, such as reliance solely on GPS technology or certain navigation techniques, do not encompass the comprehensive approach required for wilderness search operations.
