Read the sample paragraph.
Gardner River Canyon
The north entrance road from Gardiner, Montana, to Mammoth Hot Springs, Wyoming, runs along the Gardner River. It winds into the park and up the canyon, past crumbling walls of sandstone and ancient mudflows. The vegetation is much thicker in the canyon than on the open prairie below. The common trees are Rocky Mountain juniper, cottonwood, and Douglas fir. In the flatter, flood-prone sections of the canyon, low-growing willows crowd the river's edge.
