10:25 AM: Thanks to Alisa and Kersti for the tip – if you look westward across the Sound, you might see orcas. Orca Network had a report of northbound whales headed toward Blake Island, along the west side of Vashon, as of an hour ago. We are at Constellation Park but without binocs. Let us know if you see orcas!
11:15 AM: Update – they were most recently seen passing Restoration Point on Bainbridge Island [map], which means they might be in view looking north from the west end of Alki.
