The blaze, dubbed the Roblar Fire, erupted in the northeastern reaches of the northern San Diego-area Marine Corps base on Saturday, Cal Fire reported.

As of Monday afternoon, military and civilian crews had the burn area about 20% contained, according to Camp Pendleton public affairs.

The fire caused no reported structural damage or injuries and posed no threats to developed areas on or off the USMC installation, officials said.
