Black oaks, blue oaks and the alders and willows along creeks now leaf out, turn and bare on dates taken from Sierra records, and by height: a stand on a canyon wall turns before one in the valley and leafs out later. At about 1,500 m a black oak leafs out from mid May to mid June, peaks in color around October 27 and is bare by late November. Far forest trees turn and go bare with them.
After a snowfall the snow sits on every tree crown where snow lies at that height, and it stays while the air is below freezing, so a cold morning after a storm is white and a warm afternoon is mostly shed. Meadow flowers and sward green up and cure with height too: a meadow 1,000 m higher greens about two months later. Snow lines on the ground itself, and earlier melt on south slopes, are not drawn yet.
