China ? Searchers found a body that is thought to be one of two American climbers lost for more than a month on a remote mountain in southwestern China, while the second was still missing and presumed also to be dead, a search coordinator said Wednesday.

The team had not identified the body, which was partly buried by snow, said Arlene Burns, a friend of the missing climbers, Christine Boskoff and Charlie Fowler of Norwood, Colo.

“The rescuers were told to take pictures without disturbing anything. They will go back up in the morning with shovels,” Burns said from Telluride, Colo., where she was helping coordinate the search.

Boskoff, a top female climber, and Fowler, a well-known climbing guide and photographer, were reported missing after they failed to return to the United States on Dec. 4. The search was hampered initially because the two did not leave details of where they planned to climb.
