We actually had the first sign that spring was arriving a few days ago, when Security put out a warning that a brown bear had been sighted on the field. The brown bears do hibernate all winter (unlike the polar bears), so one out and about was the first sign of spring.
Don't let this picture fool you, spring in Prudhoe is WHITE. The snow is just starting to melt on top during the sunny days, and freeze into solid ice at night. Walking across the parking lot is a nightmare, worse then walking on a frozen lake.
According to the Wunderground.com, we're up to 21+ hours of visible light each day and 17 hours & 43 min of actual sun above the horizon. Tomorrow the sun will be up another 10 min and 28 seconds longer then today, so 24 hours of sunlight will happen shortly.
