This artesian well is at Jennings Environmental Education Center (a state park). The bold blue where the water is hitting the rocks is actually a bright rusty red in real color. This well has a high iron content. It is probably connected to an abandoned deep coal mine nearby. There is an abandoned-mine-drainage treatment system elsewhere in the park, maybe a 1/4 mile away from this well. This image was taken with an Nikon D70 that has been internally modified to photograph at 590nm and above in the infrared spectrum. I enjoy how this wavelength does nice things to stone. It is also easier to get a deep blue sky, one of the hallmarks of IR false-color photography. You can see the blue sky peaking through the trees behind the fountain.
