Quick Answer
To choose a blind location based on thermal currents, identify areas with a mix of sun-exposed and shaded terrain, as these create natural temperature contrasts that drive thermals. Look for rocky outcroppings, ridges, and areas with dense vegetation, as these tend to produce strong thermal currents. Use a thermal imaging device or observe animal behavior to pinpoint the hottest thermal pockets.
Understanding Thermals
Thermals are columns of rising warm air that form when the sun heats the ground unevenly. In mountainous terrain, thermals often develop in areas with a mix of sun-exposed and shaded ground, creating natural temperature contrasts. Identify these areas by looking for rocky outcroppings, ridges, and areas with dense vegetation, as these tend to produce strong thermal currents.
Locating Thermals with a Thermal Imaging Device
Using a thermal imaging device can help you pinpoint the hottest thermal pockets. These devices detect heat signatures, allowing you to see the rising columns of warm air. When using a thermal imaging device, look for areas with a high concentration of heat signatures, often surrounded by cooler air. This indicates a strong thermal current.
Reading Animal Behavior to Find Thermals
Observe animal behavior to pinpoint areas with strong thermal currents. Animals such as birds, deer, and elk often use thermals to their advantage, flying or moving upwind to take advantage of the rising air. Look for areas where animals are consistently moving upwind, as this indicates a strong thermal current. Use this information to locate areas with rising warm air and set up your blind accordingly.
