avalanche control

The road over Sylvan Pass east of the east entrance of Yellowstone National Park reopened Friday evening after the discovery earlier that day of an unexploded device used for avalanche control, a park spokeswoman said.

Rescuers narrowed their search Wednesday as they continued to look for two men missing since the weekend after heading  out on skis into the back country at Grand Teton National Park. 27-Year-old Walker Kuhl of, Salt Lake City and, 31-year-old, Gregory Seftick, of Columbia Falls, Montana went up Garnet Canyon Saturday and didn't return.
