This is a nice photo that captures the electric fountain at City Park in Denver, Colorado. Mayor Robert W. Speer and F.W. Darlington, an engineer with the Denver Interurban Railway, dedicate the new marvel in City Park Lake’The Prismatic Electric Fountain. The Fountain features electric lighting effects that have not been seen before by the public. Eleven columns of brightly colored light stream through the dramatic changing patterns of water. High in the north tower of the City Park Pavilion, an operator sits at a roll top desk, moving levers to undulate the twelve sets of water features and make the columns of light change color to the sounds of the Denver Municipal Band.”Denver Municipal Facts’May 22, 1909″
