Route & General Observations
Quick park and poke to look at front range structure ahead of this early December storm. Was able to jump on several small test slopes as I progressed into slightly bigger terrain. Whumpfing, shooting cracks and avalanching on everything! I ended up shouldering my skis and hiking down the avalanche debris. No skiing to be had today!
|Trigger||Skier||Avalanche Type||Hard Slab||Aspect||Northwest|
|Elevation||2400ft||Slope Angle||34deg||Crown Depth||24in|
Triggered this hard slab with my first step from bare tundra onto thin part of the slab. Wish I had my camera at the ready cause I was very confident I'd get this feature to avalanche given widespread collapsing/ cracking on my way up to this point.
Weak layer was 2-3mm facets at the ground. Slab was 6" - 24" deep. HS-AS-R1D2-G
Obvious signs of instability
|Recent Avalanches?||Yes||Collapsing (Whumphing)?||Yes||Cracking (Shooting cracks)?||Yes|
Able to produce whumpfs and shooting cracks in smaller terrain as I climbed toward this slope.
Storm felt like it was beginning to ramp up as I was out.
Wind: 20-25mph from the East, actively cross loading gully features.
Precip: -1cm/ hr
Pencil hard wind slab or bare tundra above tree line.
Shallow. HS at pit location was 25cm. Dug a snowpit adjacent to avalanche.
ECTV x 5. Could not isolate a column without the entire column failing at the ground.
Was able to identify 2 distinct wind slabs above the basal facets. Everything was failing at the ground.
