Camp Pendleton Noise Generating Events
From time to time the noise from Camp Pendleton can be strong in San Elijo Hills. Last night dogs, people and coyotes appeared to feel the shock waves.
Depending on atmospheric conditions, the sound of the explosions may be amplified and heard up to 50 miles away.
