Trouble at Yellowstone
by Minnie Crockwell
Minnie and Ben are off to Yellowstone National Park! Bison, bears, wolves, elk, moose, antelope and deer roam the valleys, bighorn sheep and mountain goats climb the hills, geysers spew fountains of steam and water, hot springs and mud pots abound. But not everyone is happy! Minnie and Ben discover what's left of a tourist and must solve The Trouble at Yellowstone.
