- ‘With a little luck and patience, you can see moose, pronghorns, bighorn sheep, coyotes, wolves, black bears, and grizzlies as well as ospreys, trumpeter swans, bald eagles, and lots of other birds.’
- ‘The white form below us was not a rock but one of the most beautiful and graceful of creatures, the trumpeter swan.’
