NORTH MYRTLE BEACH — Authorities said a wildfire that burned nearly 30 square miles along the South Carolina coast is completely contained.

The South Carolina Forestry Commission announced Tuesday that the fire won't be considered controlled until it no longer produces any heat.

Forest officials also said they have not found any evidence directing them away from their belief that the wildfire started April 22 when a trash fire set four days earlier rekindled.

The fire destroyed 70 homes and caused $25 million in damages.
