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.

"We did conduct quite an extensive search Tuesday and we had four teams, two dog teams, as well as air support trying to see if we could pick up anything in perimeter areas around the meadows which is in Garnet Canyon."

Grand Teton National Park, Spokeswoman Jackie Skaggs, says, as of 4pm Wednesday, teams still had found no sign of tracks or gear.

The search today was narrowed to the area in the canyon where an avalanche apparently occurred. The area is rugged and crews have done some avalanche control in order to stabilize slopes.

Skaggs says it's believed the men were carrying avalanche gear, including beacons.

"We're listening for that as well. So, once again, using a lot of staff, a lot of tools, but hoping still to find these two gentlemen and bring them to safety."

Skaggs says similar operations are planned for tomorrow, weather permitting.
