A mineralogically interesting artifact, probably from the 1960s, of a boxed set of four orthoclase crystals with different crystal habits from the West Maroon Pass area of Colorado. There is a simple orthoclase crystal, a Carlsbad twinned crystal with an intergrowth and right and left Carlsbad twinned crystals. Someone was quite serious about their collecting and assembled all of the orthoclase crystal forms typically found at this famous Colorado locality. 14.7 x 10.8 x 4.0 cm
