I found this in my archives, I thought I had lost my Mexico pictures due to some over zealous housekeeping, but on having a clear out I found some old cd's. This was taken in 2002, using the first digital camera, a hewlett packard compact, which cost a lot of money way back then!
Chichen Itza is the most fascinating place, the pyramid El Castillo was built to align exactly with the spring and autumn equinox when the shadows at dawn line up with the corners of the pyramid to show the serpents along the edges. The mind boggles at the intelligence needed to complete this.
The climb up to the top of the pyramid is fairly easy, but coming down is a different matter as you are quite exposed to the steep steps.
