 Drainage/Route:  Titus Observed Terrain:  8600-9900', NE-E-SE-S Zone/Region:  Smoky & Boulder Mountains
WEATHER OBSERVATIONS
 HN24: 2-5cm HST: 10cm Sky: CLR Precip: Temps: 30s F
 Ridgeline Wind: Calm
 Blowing Snow: Prev Snow Available for Transport: Small amounts
 Comments: Short tour, only out from about 10030-1300hrs
AVALANCHE OBSERVATIONS
 No. Location Date Size Type Trigger Aspect Elevation Comments
 1 Cerra Ciento W ridge Within past week 2 SS U W 9600' crown visible from wind slab, appeared to be last storm but I'm not positive it wasn't an old crown that had blown in. No debris visible.
 3 Boulder Mts Today 1 WL N S alpine a few small wet loose visible on the drive back to Ketchum around 2pm
 Comments: We ski cut/pushed a couple tiny dribblers on E/SE aspects, ~38*, near 9200-9300' around 1pm.
SNOWPACK OBSERVATIONS
 HS: Not observed 
 Upper Pack: New snow from last night (dry PP) above 4/7 and 4/8 dense snowfall...4/7 rain crust of varying thickness and hardness present to >9500' (crust frozen and hard on due north below 9000', frozen and thinner above 9000')... 
 Middle Pack: snow still moist below rain crust on solars, mostly dry below rain crust on shady , mixed bag on E 
 Lower Pack: Not observed 
AVALANCHE PROBLEM ASSESSMENT
Avalanche Characteristics
Character/Avalanche Problem:
Wet Loose

Layer/Depth:
4/7 rain/snow interface

Likelihood of Triggering
Sensitivity:
Stubborn

Spatial Distribution:
Specific
Terrain
  Primary Concern Comments: The problem seemed to be on the edge of being a problem when we left (getting worse).
 
Avalanche Characteristics
Character/Avalanche Problem:
Wind Slab

Layer/Depth:
20-40cm

Likelihood of Triggering
Sensitivity:


Spatial Distribution:
Isolated
Terrain
  Problem 2 Comments: Not much to add from Terry's obs from yesterday - isolated wind slabs. We did not test them. Glassing the neighboring peaks indicated there was move of a wind slab issue in true alpine terrain, but it did not appear to be widespread.
STABILITY TESTS
 Stability Test Results:
SNOW STABILITY
 Snow Stability Rating for your observed area: Good Confidence: MODERATE Trend: Worsening
 Comments (aspects and elevations of instability, etc): W-SW-S were going to be worth watching for WL this afternoon.
BOTTOM LINE
 Comments: Wet loose problem was just getting started when we left at 1:00PM. We were able to push little dribbles on very steep slopes - guessing the slope angle needed would have decreased this afternoon. Snow was still dry and cold on N and N/NE...moist on E/NE...wet on E and S.
