Section 5 of "A Glossary of Vail Valley Names" focuses on the names of the natural feaures of Vail: its mountain ranges, peaks, streams, and creeks. What's in a name? The Simontons link the rich heritage of Eagle County pioneers and early development to the names of our trails, mountains, peaks, and mountain ranges. Each description also provides context of this mountainous area in terms of others in the state.
