[PW] Lighting of Mt. Rushmore

[Elise Mackenzie]

Would anyone know where to find information regarding the lighting of
Mount Rushmore, such as:
 --type of lighting, what lights are made of
 --how much power is used
 --how many lights are used

We have checked various websites, including the National Parks site,
PBS American Experience program on Mt. Rushmore, various tourism
sites.  We have also consulted several encyclopedias and almanacs.
Most of the numbers that we come across are related to the monument's
size.  Mention of lighting is usually made only in describing the
nightly lighting ceremony.

Thank you for any suggestions.
Elise
