Lava has reemerged at Pu'u O'o vent, creating a vast, slowly circulating lake of lava, as captured from the USGS cams at dawn on 7/8/07. During the day, it doesn't look like much, but try the live Pu'u O'o Webcams around dusk (7-9 Hawaiian) or before dawn (~5:30 AM Hawaiian) and you should see a rare sight.
