The scientific reasoning explaining why differing pitches and timbres emanate from thousands of rocks in the formation is a little vague, and some Montanans prefer a more mystical explanation, especially since legend has it that rocks taken out of the formation no longer ring. It is believed that the ringing is a combination of the composition of the rock and the way the joining patterns have developed as the rocks have eroded away. This is a spectacular forest setting, and the ATV and UTV riding is rated as requiring moderate or less experience.
