"... and jocund day
Stands tiptoe" etc., but there is definitely no mist on the mountain tops this morning. The sky is a clear,cobalt blue from on side to the other. Last night it was rather cold. At lower elevations there (below 1,200 m a.s.l.) there is a definite "spring like" melt freeze cycle taking place. Thus there is a 3 cm crust in the valley bottom that can be walked on.

The weather forecast is still calling for snow this evening. But then only two types of people who forecast the weather in the mountains: more on that later.

Once again our on-slope team of observers report lots of rocks and other obstacles (mysterious holes, drainage ditches, odd bits brick-a-brack) on the lift accessible, groomed terrain. This is especially true at the lower elevations. Below 1,100 m a.s.l. the snow has been going through a diurnal melt-freeze cycle.


The Hira Kawa Snow Study Plot (830m) the 0700 hr. reading is:
Sky: clear sky
Temperature: Present: -6.5C
Maximum: 5C (-3C was observed at 1300 hrs. at 1730m a.s.l., above the Tsuga Ike Lift Company area)
Minimum: -7C
Wind: calm
Precipitation: nil
Barometer and trend: 927 hPa and falling slowly
Height of New Snow (HN): 0 cm
Height of Snow on Ground (HS): 21 cm
Crust: 3 cm


The back-country teams both dug snow-profiles yesterday. One was at 1,730 m a.s.l. on an East exposure with a 185 HS. This was near the mid-span tower of the upper gondola lift at the Tsuga Ike Lift Company area. The second team dug at 2,300 m a.s.l. with a 3 m HS. This was on South-east exposure above the Happo One Lift Company area. Both profiles showed similar developments in the snow pack: the upper 90 cm is faceting with a marked faceting just above the melt-freeze or ice layer at 95 cm (compression test: moderate with 14 blows producing a clean shear just above the melt-freeze layer in the Happo One profile. At the Tsuga Ike site this layer was not tested due to time constrains on the guided party involved.) Today another team is getting packed to leave even as this report is being typed. They are headed for the terrain above the Happo One Lift Company area. The dramatic results of this investigation will be posted here tomorrow.
