CBS News reports Shelley Johannesen, 53, was descending from the summit of the fifth-highest peak in the world when she and three others were caught in the slide.
She was climbing with her partner David Ashley and two Nepali guides.
Ashley and one guide were injured and flown to a Kathmandu hospital along with Johannesen’s body.
The other guide shared his account of the avalanche with Explorers Web, saying that no one was buried in the slide below Camp 3.
On Facebook May 5, Johannesen said the team had been stuck at Makalu’s base camp waiting for the right weather and planned to start the climb to Camp 2 on May 6.
Live tracking data from Ashley and Johannesen shows they summited the nearly 28,000-foot mountain on May 8.
Johannesen and Ashely ran the Kamas-based Dash Adventures which partners with locally-owned and operated guide companies for trek and climbing expeditions.
In a Facebook post on the company’s page, Ashley said Johannesen died in his arms on the mountain from injuries sustained in the avalanche nearly 24,000 feet up on the mountain.
Johannesen is the fourth climber to die in the Himalayas so far this season.
