The Crater of Diamonds State Park is an Arkansas State Park located near Murfreesboro in Pike County, Arkansas, USA containing the only diamond-bearing site in the world that is open to the public.

The Crater of Diamonds State Park is a 911-acre (369 ha) Arkansas State Park situated over an eroded lamproite volcanic pipe. The park is open to the public and, for a small fee, rockhounds and visitors can dig for diamonds and other gemstones. Park visitors find more than 600 diamonds each year of all colors and grades. Over 29,000 diamonds have been found in the crater since it became a state park. Visitors may keep any gemstone they find regardless of its value (and some, as listed below, have been quite valuable).

In addition to diamonds, visitors may find semi-precious gems such as amethyst, agate, and jasper or approximately 40 other minerals such as garnet, phlogopite, quartz, baryte, and calcite.

The crater itself is a 37.5-acre (15.2 ha) plowed field. It is periodically plowed to bring the diamonds and other gemstones to the surface. The remainder of the park consists of a visitor center, interpretive Diamond Discovery Center, campground, picnic area, and Diamond Springs aquatic playground. A 1.3-mile (2.1 km) walking trail along the Little Missouri River is available for hikers.

The park is open throughout the year.

In August 1906, John Huddleston found two strange crystals on the surface of his 243-acre (98 ha) farm near Murfreesboro, Arkansas, and soon became known as the first person outside South Africa to find diamonds at their original source. The following month, Huddleston and his wife, Sarah, sold an option on the 243 acres (98 ha) to a group of Little Rock investors headed by banker-attorney Samuel F. (Sam) Reyburn, who undertook a careful, deliberate test of the property.

After 1906, several attempts at commercial diamond mining failed. The only significant yields came from the original surface layer, where erosion over a long period of time had concentrated diamonds. In the early period, 1907-1932, yields from this "black gumbo" surface material often exceeded thirty carats per hundred loads (50 mg/Mg) (standard 1600-pound tramload of the early period). Highest yields from the undisturbed subsurface material (described as kimberlite or volcanic breccia, by the U.S. Geological Survey) were two carats per hundred loads (3.5 mg/Mg) in 1908 and about two carats per hundred short tons (4.4 mg/Mg) in 1943-1944.

Because equipment of the early period usually included bottom screens with mesh larger than 1/16th inch (1.6 mm), thousands of smaller diamonds were allowed to pass through. The bulk of these ended up in drainage cuts of varying depths all over the field and in the big natural drains on the east and west edges of the diamond-bearing section of the volcanic deposit (approximately 35 acres (14 ha) of volcanic breccia on the east side of the 80-acre (32 ha) pipe). In recent decades, those small diamonds have been the bread-and-butter of recreational diamond-digging.

Soon after the first diamond was found, a "diamond rush" created a boomtown atmosphere around Murfreesboro. According to old tales, hotels in Murfreesboro turned away 10,000 people in the space of a year. Supposedly these aspiring diamond miners formed a tent city near the mine which was named "Kimberly" in honor of the famous Kimberley diamond district in South Africa. On the other hand, all available evidence indicates the Town of Kimberly originated as a land-development venture in 1909, initiated by Mallard M. Mauney and his oldest son Walter on their land immediately south of Murfreesboro. The project failed soon afterward as the speculative boom generated by the diamond discovery collapsed. Today the Kimberly area is almost all cow pasture, owned by Mauney's descendants.

From 1951 to 1972, the crater hosted several private tourist attractions. The first, The Diamond Preserve of the United States, lasted only about one year. In late 1951, Howard A. Millar stepped in and salvaged the infant tourist industry. In April 1952, Millar and wife, Modean, launched their "Crater of Diamonds" attraction. Howard Millar, an accomplished writer and promoter, stirred unprecedented national publicity and drew enough visitors to sustain the operation. In March 1956, a visitor found the "Star of Arkansas" on the cleared surface. The rare beauty weighed 15.33 carats (3.07 g). Later, Roscoe Johnston opened a rival tourist attraction, the "Arkansas Diamond Mine", on the main part of the diamond field.

The rivalry between the two tourist operations left both in a weakened position. In 1970 the entire volcanic formation was consolidated by a private partnership which then reassigned the property to General Earth Minerals (GEM) of Dallas, Texas. GEM expected to turn the property over for a profit, but ended up heavily indebted to GF Industries (GFI) of Dallas. Upon default, GFI too

The boardwalk, measuring 40 feet in diameter, extends through the neighborhoods of Hammels and Seaside. In 1938, Parks acquired the land through condemnation under the direction of Commissioner Robert Moses. Shore Front Parkway was built a year later. The beaches continue to attract over one million people each year.

Lifeguards are stationed on the beaches from Memorial Day through Labor Day. Visitors enjoy basketball and handball courts, roller-hockey rinks, sitting areas and playgrounds along the boardwalk and adjoining areas. Recent improvements to the area include the installation of “Whaleamena,” a sculpture of a whale that was originally part of the Children’s Zoo in Central Park. The whale was donated by Parks and subsequently restored by local volunteers. “Whaleamena” is located at the entrance to the Boardwalk at Beach 95th Street.

In 1999, for the first time in a quarter century, the entire boardwalk was open to the public following a multi-million dollar restoration project. The project included the repair of the boardwalk, the addition of spray showers and handicap accessible drinking fountains, and the installation of modern playground equipment between Beach 82nd and 86th Streets. The improvements also included the renovation of “The Wave” bus shelters. The interiors of the shelters now contain murals, painted by artist Ester A. Grillo, which depict aquatic scenes.

Fully illustrated guide to identifying water-dwelling macroinvertebrates
A handy resource for anglers, students, biologists, or anyone else spending time near rivers and streams
Gives tips for distinguishing similar species and includes information for each species on behavior and role played in the ecosystem
From the damselfly to the whirligig beetle, our nation's streams are teeming with critters. This convenient, inexpensive guide allows you to identify any that you find--whether you're working on your fly tying, researching the local insect life, or just mucking around in the river. Also includes information on the river conservation and management work performed by the Izaak Walton League, making this an especially valuable resource for stream monitors, biologists, and other specialists.
