The family soon discovered Blaze had broken through a barrier and fallen down the well.
Crews from North Whidbey Fire & Rescue, Central Whidbey Fire & Rescue and the Whidbey Island Naval Air Station responded to the property to plan a rescue.
Personnel from the naval air station climbed into the well to sedate the horse, and the animal was then fitted with a harness to be hoisted to safety.
Blaze was returned to solid ground and found to have incurred only minor injuries to his legs. Lang said the horse was fortunate that he had fallen tail-first into the well.
"If he had gone down any other way he wouldn't be alive," Lang told KING-TV. "Luckily he went down heinie-first."
