My grandfather found a large, petrified (we thought) tooth along the banks of the Duwamish River when he was a kid, and we always wondered who it had belonged to. Enter the Burke Museum and its annual Artifact ID Day -- a few years ago, a curator examined the tooth and pronounced it "horse." Do you have something unidentified -- cultural artifact, fossil, horse tooth -- lying around the house? Dig it out and head to the Burke today. Experts from the museum will tell you what you got.
Get a dose of light and shake your fist at winter at the Seattle Center's solstice celebration (Saturday and Sunday beginning at 4 p.m.), which was cancelled a couple of weeks ago because of the big storm. Fire!
