Written Report:
Today I toured around the Todd Lake area. Skiing the east aspects down to to Todd Lake I found 30-40cm (12-16") of new storm snow well bonded to the rain crust formed earlier in the week. At 9:30am, on the ridge at 6445ft, winds where calm, visibility good with overcast skies, it was snowing wet snow at about 1cm/hr (0.4"/hr), air temp was -1c (30f). I did not see signs of instability, ie cracking, whumpfing, natural avalanches, etc, on this aspect.
Skiing the N/NE chutes off Soda peak I did encounter some snow instability. Just below the peak, snow release from a tree had triggered a small point release, Loose Dry, that ran perhaps 5m (16ft). Skiing the NE gully I triggered a R2,D1 Loose Dry that ran within the top 5cm (2") of snow. I did not see any deeper instability in the snowpack in this area. While Loose Dry avalanches are usually relatively harmless to people it is worth remembering they can carry you into terrain traps (gully, rocks, dense timber, cliff).
Leaving Todd Lake at around 2pm temps had warmed to around 0c (32f), with precipitation verging on rain.
