The grisly discovery was made on July 12 by climbers hiking along the Theodul Glacier in Zermatt, police in the Valais canton said on Thursday.
"DNA analysis enabled the identification of a mountain climber who had been missing since 1986," the police said in a statement.
"In September 1986, a German climber, who was 38 at the time, had been reported missing after not returning from a hike."
The climber's remains underwent a forensic analysis at Valais Hospital, allowing experts to link them to the 1986 disappearance, the police said.
Last year Switzerland's glaciers registered their worst melt rate since records began more than a century ago, losing 6% of their remaining volume -- nearly double the previous record in 2003.
