JACKSON, Wyo. — Four people were caught and carried in an avalanche on the Spoon couloir near Disappointment Peak in the Teton range on Tuesday, April 1, according to the Bridger-Teton Avalanche Center (BTAC).
BTAC’s report states that four riders were partially buried after climbing up the couloir in very steep, wind-loaded terrain.
“The avalanche broke at the top of the feature where the slope rolls over and becomes steep,” BTAC writes. “Crown depths ranged from 8 inches to 2.5 feet. No critical injuries reported.”
Jenny Lake Rangers responded to the incident, according to BTAC, but the group was able to self-rescue.
In Wednesday’s avalanche forecast, BTAC notes that Tuesday’s event exemplified “how quickly conditions can change when we transition to wind-loaded slopes.”
Wednesday’s avalanche danger is considered “moderate” above 9,000 feet in the Tetons, and “low” below that threshold.
“Heightened avalanche danger exists at upper elevations on very steep, wind-loaded slopes,” BTAC writes. “Soft slabs up to 2 feet thick are possible, and avalanches could be large enough to bury or injure you. Look for drifted snow and watch for shooting cracks. The danger is greatest around cliffs and steep wind-loaded features like couloirs. Give cornices a wide buffer. Avalanches are unlikely below 9,000’.”
