The three movements of Adventures in Yellowstone present iconic scenes from the park. The first movement, Waiting for Old Faithful," begins with a tremolo, representing the rumbling before the famous geyser erupts, followed by figures that move up and down the keyboard depicting the shooting water. "Grand Prismatic Spring" is the second movement, a mysterious piece filled with scale-like figures and short motives based on various intervals. The last movement, "Wildlife in the Valleys," creates various moods associated with animals found in the region, including wolves, bears, and buffalo. The exciting ending concludes with a glissando and fortissimo chords."
