If you're inclined to learn more by listening instead of reading, consider purchasing a copy of the Audio Tour of Pikes Peak-America's Mountain. Approximately 50 minutes in length, the audio tour presents historical, natural and geologic information about the mountain, the highway, the Cog Rail and significant events that occurred on Pikes Peak in Colorado Springs, CO. The audio tour is designed to be played as you drive on the Pikes Peak Highway from the tollgate to the summit, but you can just as easily listen to it from the comfort of your living room.
