The ranger noticed the building had been broken into and set on fire around 10:15 p.m. After a lengthy chase by the ranger, the male suspect escaped in dense brush, GGNRA spokeswoman Shalini Gopie said.
Rangers and U.S. Park police set up a perimeter and roads were closed in the headlands until the morning. A U.S. Coast Guard helicopter and a California Highway Patrol helicopter and fixed-wing plane searched the area for the arson suspect, Gopie said.
The fire at Building T-828 on Bunker Road was reported around 11:00 p.m. and the structure was engulfed in flames when firefighters from several agencies arrived, Southern Marin Fire Protection District Battalion Chief Matthew Barnes said.

The cause of the fire remains under investigation, Barnes said.
