Early snowfalls, unless accompanied by severely plummeting temperatures, do not permanently affect deer habits or forage. However, snow in the air spurs deer to greater daytime activity. Most important, it opens opportunities for hunters who were previously confined to tree and ground stands while dry leaves crackled underfoot. When fresh snow falls and sticks, you have perfect tracking conditions. When it melts, the downed leaves become wet and pliable, silencing the footsteps of still-hunters. Falling snow also obscures your outline and movements, carries odors to the ground, and permits a closer approach. It's easier to spot animals in the stark world revealed after a snowstorm, but keep in mind that the reverse is also true.
