About 40 people Thursday continued searching an area in the southern part of Yellowstone National Park where an authority on geysers and a park volunteer may have been buried by an avalanche.
Officials said rescue teams have determined that Roderick Hutchinson and the woman volunteer skied into and out of one snow slide, and there were ski tracks into but not leaving the second slide area near Heart Lake.
Hutchinson, a park research geologist who lives at Old Faithful, has worked at the park for nearly 30 years. The name of the woman was not released.
Hutchinson had an encyclopedic knowledge of the park’s thousands of thermal features.
