Occasionally the dog's alert may be difficult to interpret. Complex combinations of change in terrain and vegetation, air movement due to temperature variation, and obstacles can all create scent pools and scent voids remote from the body. Figure 11.7 [right] illustrates the creation of several scent pools and voids formed as the scent rises up slope from the body, pools behind a rock, flows over the top of the tree and pools behind it, and continues to form a secondary scent cone on the far side of the bush. Consider alternative explanations for scent origin that takes into account these factors.
