A spring-like breakup continues on Mendenhall Lake. The ice on the lakeside trail that made talking dangerous just three days ago is gone. Rainwater pools on the lake ice, Cracks and open water are sure to follow unless winter returns. The most dramatic change is in the icebergs. The less-dense ones have softened until they look like sculptures of turquoise snow. One, fashioned on the denser old ice looks like the armored spine of a submerged dragon. Above all this melting, ghosts of fog move with purpose, caressing the bald rock hills recently exposed by the retreating glacier. Along the shore a little poodle mix trots with her Frisbee in her mouth.
