Is it wise to hunt in afternoon drainages affected by thermals?

Understanding Thermals

In mountainous terrain, thermals are columns of rising warm air that form when the sun heats the ground, causing the air closest to the surface to warm and expand. As this warm air rises, it creates areas of low pressure near the ground, drawing in surrounding air. This process creates a predictable wind pattern, with air rising in certain areas and sinking in others. By identifying areas with thermals, hunters can anticipate the movement of game, which tends to follow these wind patterns.

Identifying Thermal-Driven Movement

To take advantage of thermals, hunters need to identify areas where game is likely to move. Look for drainages and valleys that are oriented in a way that allows the thermal winds to push game upwards. Typically, this occurs in areas where the sun is directly overhead, such as south-facing slopes. In these areas, game will tend to move upwards, often in predictable patterns, as they follow the thermal winds. By observing these patterns, hunters can place themselves in a position to intercept game as it moves through these areas.

Positioning and Stalking

Once hunters have identified areas with thermals and anticipate the movement of game, they need to position themselves for a successful stalk. This typically involves getting into position early, often before dawn, and staying hidden until the game moves into view. Hunters should use cover and concealment to get close to the game, often using trees, rocks, or other natural features to get within range. By understanding thermals and their impact on game movement, hunters can increase their chances of success, even in challenging mountainous terrain.
