CHEYENNE, Wyo. (CBS/AP) — Two Philadelphia women have been ordered by a federal magistrate judge in Wyoming to spend two days in jail for leaving a boardwalk and damaging a thermal area in Yellowstone National Park. U.S. District Magistrate Judge Mark Carman also ordered 31-year-old Tara Davoli and 30-year-old Sarah Piotrowski to pay a $350 fine, about $107 each in restitution and banned them from the park for two years.

Prosecutors say the women illegally left the boardwalk in the park’s Midway Geyser Basin on June 11. Witnesses tried to stop them, but prosecutors say they damaged orange bacterial mats at Opal Pool.
