Photo gallery: Small signs of spring

Spring is a season of dramatic changes. Snow melts, and lakes and rivers open up. Hardwood forests turn green. Some animals wake up from hibernation while others return from warmer lands to the south. Dramatic as the changes are, however, many are small in size and easy to overlook. Here are some of the small sightings of spring encountered on recent hikes.
