Towering above the twisting roads and manicured homes that make up the Pacific Palisades, urban hikers seeking an escape from America's famously gridlocked city have a clear view of the pristine waters of the Pacific.

Now the green, brush-lined path in the canyons is grey and burned as far as the eye can see.

Yellow police tape surrounds the path up to the trail. Police guarding this area are calling it a "crime scene" and prevented BBC reporters, including me, from getting any closer.

It's where investigators think the deadly blaze that destroyed so many homes in the area may have started.
