The accident report is available here:
Jeffrey was that, but much more: A graduate of the University of Vermont, a trained wild lands firefighter, an accomplished mountaineer, a first-rate skier, a friend to many in Girdwood, he was also the man who designed and operated the avalanche Web site run by the Chugach National Forest.
That Web site is now out of order.
"Due to a tragic accident on the Glacier Ranger District on Thursday, Jan. 22, the Chugach National Forest Avalanche Center will not be posting advisories until the end of the month,'' the site says. "The Forest Service, the Avalanche Center, friends and family lost Jeff Nissman when a roof avalanched on him Thursday in Portage Valley.
"Jeff had worked for the Forest Service eight years, four of them here on the Glacier Ranger District. Before that he was in Juneau on the Tongass National Forest. Jeff was a key part of the Avalanche Center and the Cabins and Trails program. We were ... looking forward to his cheerful voice bringing us the morning avalanche advisories in the near future."
