Rockhounding Nevada
Nevada is an extraordinary state for rockhounding. The state – nicknamed the “Silver State” – is home to one of the greatest mineral discoveries in history, the famous Comstock Lode. Nevada, however, has a very wide variety of rocks, gemstones, minerals, and fossils. In addition, in Las Vegas, anyone can get a glimpse of the world’s largest gold nugget found with a metal detector – named the ‘Hand of Faith’ – which is located, of course, at the Golden Nugget Casino.
State Rocks, Gemstones, Minerals, Fossils, & Dinosaurs
Rockhounding Tip: Knowing state rocks, gemstones, minerals, fossils, and dinosaurs often can be very useful information for rockhounders. Ordinarily, states with significant mineral deposits, valuable gemstones, fossils, or unusual or significant rock occurrences will designate an official state mineral, rock/stone, gemstone, fossil, or dinosaur to promote interest in the state’s natural resources, history, tourism, etc. Accordingly, such state symbols often are a valuable clue as to potential worthwhile rockhounding opportunities.

Sandstone
State Rock:
Sandstone (1987)
Nevada designated sandstone as its official state rock in 1987. Sandstone, in its more traditionally recognized form or as quartzite, is
found throughout the state. The
sandstone originated when Nevada was under a huge inland sea millions of years
ago. In areas such as the Valley of
Fire State Park and Red Rock Canyon Recreational Lands, both near Las Vegas, it
provides some of Nevada's most spectacular scenery. The State Capitol, and the former United
States Mint, both are built of sandstone.

Nevada Turquoise

Virgin Valley Black Fire Opal (polished)
State Gemstones: Nevada Turquoise [semiprecious] (1987) &
Virgin Valley Black Fire Opal [precious] (1987)
Nevada has designated two official
state gemstones. Nevada designated
Nevada turquoise as the its official state semi-precious gemstone in 1987. Turquoise
is a hydrous phosphate of aluminum and copper. The copper gives it its blue color. Sometimes called
the ‘jewel of the desert,’ Nevada turquoise is found in many parts of the
state.
In addition, Nevada designated Virgin Valley black fire opal as its official state precious gemstone in 1987. Fire opal is classed as an oxide of silica with a small amount of water. Although the amount of water is less than ten percent, the water helps produce the rainbow colors when light strikes the opal. Opal, especially the fire variety, is highly prized as a gemstone. The Virgin Valley in northern Nevada is the only place in North America where black fire opal is found in any significant quantity. The opals of this region are comparable to those found in Australia. The black opals exhibit bright colors on a black background. Other types of opal are also found in the area. Much of the opal from the Virgin Valley is in the form of opalized wood. This is because the Virgin Valley was once a region of forests and lakes until it was buried by volcanic eruptions. Over time, the buried wood was replaced by silica as water filtered up through the ash layers creating the beautiful opals seen today.

Ichthyosaur - the 'fish lizard'
State Fossil: Ichthyosaur (1977)
Nevada designated the Ichthyosaur as its
official state fossil in 1977.
Ichthyosaurs ruled the world's oceans during the Mesozoic era 200
million years ago. Ichthyosaurs – whose
name means "fish-lizard" – were streamlined
marine reptiles that ranged in size from seven to thirty feet long. They had sharp teeth in long jaws, and big
eyes. They had four crescent-shaped
fins, a stabilizing dorsal fin, and a fish-like tail with two lobes. They breathed air with lungs through nostrils
that were close to the eyes near the top of the snout. They gave birth to live young (fossils have
been found with baby Ichthyosaurs in the abdomen). The Ichthyosaurus
shonisaurus popularis was the name given to a species discovered in
Nevada in 1928 (although reports state the discovery was in 1928, the
expedition to the Humboldt region is referred to as: The Saurian Expedition of
1905). Some thirty-seven of these
reptiles became stranded in mud flats from a receding equatorial sea that once
covered Nevada. The longest specimen
found at this site, located at an elevation of 7,000 feet in the Shoshone
Mountain Range near the town of Berlin in northwestern Nye County, Nevada, was fifty-five
feet long and represented the only complete fossilized skeleton of the species
ever found in the United States.

Silver Ore from Comstock Mine
State Metal: Silver (1977)
Nevada designated silver as its
official state metal in 1977. Nevada’s
nickname, of course is the ‘Silver State.’ In 1859, in
the Virginia Range of Western Nevada on the site of Virginia City, a rich
mineral deposit was discovered. This
‘Comstock Lode’ was named for Henry Tomkins Paige Comstock, a California
prospector who first laid claim to the land.
This one lode yielded more than three hundred million dollars in silver
and gold in twenty years. This bonanza
resulted in a great increase in the Nevada population. Other strikes were made but none would compare
to the size of the Comstock. The rich deposits of silver in Nevada have
been important factors in the establishment, growth, and prosperity of Nevada.

Nevada Bureau of Mines and Geology
The Nevada Bureau of Mines and Geology is a
research and public service unit of the
University of Nevada and is the state
geological survey. NBMG’s Special
Publication No. 29 – Rocks, Gemstones, Minerals, & Fossils of
Nevada is a very useful resource.

U.S. Bureau of Land Management – Nevada
The vast majority of the entire State of Nevada
is federal public lands. The majority of
these lands – over 48 million acres (a size greater than several entire states
in America) – a federal public lands managed by the BLM. In fact, the BLM manages approximately 2/3’s
of the entire land base of the State of Nevada.

Elko Meteorite Crater Field
North of Elko, Nevada
The ‘Elko Meteorite Crater Field’ is located on
federal public lands managed by the Bureau of Land Management north of Elko,
Nevada. At this site, there are about 206 craters that cover an area about 12
miles long and nearly 2 miles wide. The
craters range in diameter from 16 to 820 feet and up to 12 feet deep. It is believed that these craters formed over
6,600 years ago. No meteorites, however,
have been found at the site.
Accordingly, some suggest that the craters are a subsidence feature.
