AMAZON STONE. COLORADO.
The amazon stone and associated minerals of the Pikes Peak region, Colorado, have been a source of interest to mineral collectors and gem dealers for many years. George F. Kunz 2 states that an exhibit of Colorado amazon stone at the World's Fair in Phdadelphia, in 1876 occasioned much surprise because of its beauty. There are two gen­eral localities where the amazon stone is found, one to the east of Pikes Peak, in the Crystal Park region near Manitou Springs, and the other about 18 miles northwest of Pikes Peak around Crystal Peak, about 4 miles noith of Florissant.
In the Crystal Peak region prospects have been opened over an area more than 2 miles square by vaiious prospectors and collectors. The Crystal Peak region is mountainous and timbered, with occasional rocky knobs or domes standing above the ridges and valleys. The prospects examined are situated at elevations ranging from about 9,000 to 9,400 feet above sea level, Crystal Peak having an altitude of 9,668 feet. Crystal Peak is the highest of a range of small knobs along a divide. Other lower knobs are Little Crystal Peak, one-fifth of a mile west of north; Deer Mountain, about one-half of a mile north­west; and Sheeps Head, about two-thirds of a mile northwest of Crystal Peak. Wide ridges and rather gentle slopes extend from the foot of these knobs, but most of these are cut into by valleys within a half mile of the knobs.
The prospects are in both the gentle slopes and in the steeper walled valleys. Among the numerous people who have worked in the Crys­tal Peak region George Copelen, of Gillette, Colo., was one of the pioneers. Mr. Copelen commenced prospecting here over 35 years ago, but has now abandoned that work. Numerous claims have been filed and some of these are still in force, but others have lapsed. Among the prospects visited in August, 1913, some were on the claims of J. D. Endicott, of Canon City; The Crystal Peak Gem Co., of Ciipple Creek; A. Fries, George H. Weed, and Whitmore&Sandeis. The claims of J. D. Endicott lie chiefly north of Crystal Peak. One claim is in the gap between Little Crystal Peak and Deer Mountain. A. Fries owns patented ground about one-half of a mile northeastof Crystal Peak and claims other prospects between this and Little Crys­tal Peak. The claims of the Crystal Peak Gem Co. are scatteied, most of them lying north and noithwest of Little Crystal Peak with one, the "Pinacoid claim," nearly a mile to tne north of Crystal Peak. A claim covering the topaz workings, about li miles southwest of
