Bridger-Teton Avalanche Center

Crown profile. Fatality on March 17. Likely repeater avalanche from Jan 7th cycle. Total HS adjacent (skier's R side) to avalanche avg. 90cm. Crusts observed in other locations nearby but did not show up in this profile.

Crown profile. Snowmobile tracks below path and on adjacent slopes. Guessing remote trigger. SS-AM-R1-D1-O. Unknown date on slide, maybe within 48hrs. Bed surface at 89cm on top of crust. Tests now failing on facets below crust.

Surface snow was dry at this location but moist on south facing slopes and wet at lower elevations. Recent human triggered and natural avalanche occurred in the upper 20-30cm of the snowpack and at least one stepped down through the MFCs.

Atypical structure for area.
