The leaves were still very small and reddish.
More appear to be opening. Ericophorum is
blooming all over the slopes in the center of
T-3.

Clear and warm all day. Only clouds seen were few off

Three inches deep it was 6°C. The air shaded was

On the south slopes of Unist Mt., some Ericophorum is
shedding pollen. All are shaded out. A few Pedicea lavas
(weaver's sedge) are blooming, as well as a sweet 5
