“With the coming of the spring thaw in May in Alaska, cemeteries start burying people who died during the past seven months and have been held in storage. Winter temperatures can fall to 40 below zero or even lower at Fairbanks, in Alaska’s interior, making the frozen ground as hard as granite and the digging of graves most difficult.”

Someone else did the research of this fact. Sounded reasonable; however, this winter might have been a warmer one in Alaska also.
