Towers can be very hard to spot in the haze. There is a 1500ft
tower on the top of a 2500ft ridge between Watsonville (WVI) and
South County (E16 (formerly Q99)). On a clear day, it isn't easy
to see. With fog/haze, it becomes invisible.

I took these shots on a somewhat hazy day:

There are strobes on it, but the tower itself is a flat grey, which
is very good at blending into the haze/fog.

That tower is difficult to discern.

Because the KFI tower is so close to the airport it appears larger,
but your photo illustrates the problem well.
