Here is Window Cave from the outside.

This is the hole which gives Window Cave its name. The hole, which faces west, gives a view of Traquillon Mountain (called "alulu" - meaning "conspicuous" - by the Chumash). On the winter solstice the sun sets directly over this peak, and the sun streaming through the hole in Window Cave inches towards the sun and fertility symbols carved on the eastern wall. The next couple shots show the sun setting on the winter solstice.

The sun beam shines into the hole.

Here you can see the shadow hitting the side of the cave opposite the hole.

These are the glyphs carved on the eastern wall. They are pretty hard to see in this photo, so a line drawing is provided below.

In the upper left is a fertility symbol (a female reproductive organ) and in the lower right a sun symbol. According to Chumash lore, the world was reborn every winter solstice. As the sun sets on this day, the beam of sunlight climbs the wall and eventually comes to rest on the fertility symbol. The new world is thus concieved, and life will continue for another year.

This is a sage offering recently placed in the cave by modern Chumash.

Here is a panarama showing the ridgeling to the east of Window Cave. There are many peaks and other distinguishing features which could have been used to mark the daily movements of the sun.
