We planned to meet at the Tiller Ranger Station at 9:00. Donegan Prairie Trail is an hour drive from Tiller. Donegan is a SIA (Special Interest Area) for the Cow Creek Tribe. It is a traditional area for Huckleberry gathering. Wildflowers are those that occur in a typical high elevation meadow habitat. The hike is about 3 miles one way (requires moving rigs) or a 6 mile loop.
