Access to Mammoth Hot Springs in Yellowstone National Park from Gardiner, Montana, opened for visitors Sunday, four-and-a-half months after historic flooding tore out sections of the main north road leading into the park.

The West, South and East entrances and nearly all roads in Yellowstone National Park will be closed to regular vehicle traffic Nov. 1. The park annually closes roads at this time of year to prepare them for the winter season and snowmobile and snowcoach travel, which will begin Dec. 15. The last day for visitors to drive most roads will be Monday, Oct. 31.

Wolf management plans are faulty because the data they are based on is skewed, according to a study out this week. In researching livestock losses in Wyoming, Montana, Idaho, and Wisconsin, the authors found that "the percent of livestock killed by wolves never exceeded 0.21 percent for sheep and 0.05 percent for cattle."
