1983, Backbone State Park, Iowa: Snowmobile Riders Hear Howls
While riding their rented snowmobiles along some trails in Backbone Park, Amanda and her brother Bert Vikingstone heard a deep, sonorous rumbling that caused them to stop. Fearing something was wrong with one of the motors of the snowmobiles, Bert cut his engine while ordering his sister to keep hers idling.
Listening carefully to the hum of the motor, Bert and Amanda were startled to hear the rumbling grow in pitch and volume. The noise became a whoop that shook the tree tops. Amanda turned off her snowmobile and the two siblings sat listening to the noisy undulations.
The whoop turned into a shriek before it suddenly ceased. Frightened now, the brother and sister started the snowmobiles, turned around and raced back the way they came.
Later, while Amanda tried to imitate the sound they heard, the owner of the snowmobile rental informed the pair that they were lucky because they had heard the cries of a Bigfoot. Some people wait their whole lives and never ever hear even a peep.
Amanda believed what they heard was a Bigfoot, while Bert remains incredulous.
