While prospecting for gold, treasure hunters should keep an eye out for diamonds in Colorado. Kimberlites have been found in the State Line district near Fort Collins, and all have yielded diamonds in this area. Placer diamonds were found in Fish Creek, Rabbit Creek and George Creek near the state line and other kimberlites were found near Estes Park and the City of Boulder. Cryptovolcanic structures similar to kimberlite is found all over - particularly in the Red Feather Lakes area.
