More chilly weather lingers in our Sierra, with a winter storm warning starting tomorrow night, and several more inches of snow expected above 6000' again. The river has dropped to 1500 cfs at Pohono Bridge.
Highway 41 was closed for a time yesterday due to snow and vehicle accidents. A rockfall closed the Yosemite Falls Trail this morning. These are January scenarios, yet it'll be June next week.
Ribbon Creek carried frazil ice yesterday. Steve Bumgardner's terrific frazil ice video has been featured on the world's number one blog, boingboing: http://www.boingboing.net/2010/05/24/frazil-ice-fascinati.html#comments. Pete is honored.
Concentrated numbers of yellow-rumped warblers on this morning's birdwalk. Juncos were both flocking and singing.
Poison Oak on the Valley floor is about 50% leafed out, though it may have some frost damage. Yes, there is p.o. on the floor of Yosemite Valley, but you have to be remarkably unlucky to stumble into it. Farewell-to-spring (Clarkia) is blooming in El Portal now; given the conditions a little higher up it seems premature to bid farewell to a a season we've only glimpsed.
