Last one of the North Head Lighthouse...

1st 2 pics are showing the time elapse camera and website related to documenting the erosion of Benson Beach... 

The collection of sand that formed the campground area is now being reversed and 260 acres has been lost since the peak. 

Life is a Circle Baby!

The next 4 pics are related to the light of the lighthouse. 

The 6 bulb assembly rotates through one bulb at a time - Yep - you got that right.....

One little bulb makes all that light....

Thought the magic of reflected light...

The 1st generation Fresnel lens was built in 1822 for $3000 - $6000.....

It is estimated it would cost $6 million to build it now. 

That's Old World Craftsmanship!

This place is AMAZING!!!!
