Observer Comments

Remote triggered storm slabs, was riding in a meadow above the power line trail on the motorized side of turnagain. I was riding near the base turned out and remote triggered a slab on both sides of where I turned around about 200 and 150 ft to either side of my turn and a long ways above me. I was notified by my riding partners via my BCA radio and was able to get out of harms way before it got to me. We all have formal training and know better. Unfortunately vis was too bad to get pics or a good visual on the starting zone.

Being a long time turnagain rider, I haven’t seen avalanche activity on that slope or area often.
