Garnet Hill

Download Road Log Garnets are crystallized minerals formed in igneous rocks. Larger garnet stones are precious gems due to their clear color and beauty. Garnet jewelry has been found in Egypt dating back to 3500 B.C.; it reached the height of fashion in the Victorian era. Many ancient myths are associated with garnets. In ancient times, images of lions were engraved upon garnet gems with the belief that this produced a magic amulet or charm providing the ultimate in protection. Throughout much of European history, superstitions persisted that garnets could prevent bad dreams and were able to cure diseases of the blood. Today, garnet remains a popular gemstone and is the birthstone for those born in the month of January. Garnets are also an important industrial mineral used as an abrasive in sand blasting and in manufacturing garnet sandpaper.

The Evolution of Garnet Hill

The volcano that produced the garnets in this area erupted the same time mammals were becoming dominant and modern plants were evolving, between 32 and 40 million years ago. In that era, Garnet Hill was actually several hundred feet below the volcano's surface. Rhyolite, which is a fine-grained igneous rock that is the volcanic form of granite, was being formed within the volcano. Rhyolite forms when magma erupts from the surface or invades rocks at a very shallow depth. As the molten rock cools, gases form pockets or vessicles in the rock allowing the garnet crystals to grow. The garnet crystals formed from the last bit of liquid cooling within the rock. The crystals vary in size, from small grains to crystals of one-quarter inch in diameter, and color of deep red to brownish red and orange. Rarely crystals of one half-inch size are found here. The garnets found at Garnet Hill are of the almandine group. Almandine is composed of iron, aluminum silicate and is deep red or brownish red in color.

History of Garnet Hill

The garnets were probably first noticed by early prospectors (1870's) searching for ore deposits in the area. A. C. Spencer of the U.S. Geological Survey wrote a report on the ore deposits in and around the Ely, Nevada area. It has since been mentioned in various mineralologist magazines and remains popular with mineral collectors.

On December 22, 1970, Garnet Hill and the surrounding area were withdrawn from mineral entry when the Garnet Fields Rockhound Area was created to ensure continued public recreational and scientific uses of the site.

Find Some Garnets!
Garnet Hill

Garnet Hill has drawn national attention for its beautifully rich, dark red garnets buried within the hillsides on the outskirts of Ely. These garnets are found in the rhyolitic volcanic rock that so densely populates the region.

The garnets at this site may be found by two methods: by finding them on the surface or by digging and breaking rock.

To find them on the surface, look in low spots and gullies. As time passes, the garnets that are embedded in the rock are exposed to the elements and some eventually separate from the rock where they were formed. They end up being washed downhill and collect in depressions, somewhat like placer gold in a stream. As you search the ravines, keep your eyes open for dark red dots in the dirt and rubble, and you just might find a garnet or two.

If you prefer a more aggressive approach, you'll need a few tools to help you along. The basics are safety goggles, leather gloves, rock hammer, chisel, pry bar, pick, shovel, drinking water and something to hold the treasures you find. On summer days, a hat for protection from the sun is also a good idea.

First, pick a spot, dig a hole, gather the rocks you dig out and examine them. What you're looking for are rocks with holes in them. Carefully break them apart and see if you get lucky. Not all rocks will have garnets, but if you're persistent you are sure to be successful.

When you find something...

Lots of people just take home and display their garnets as they found them. You can also chisel them out of the rock and clean them up. Garnets are brittle, so be careful as you chisel away. Once the garnets are out of the rock, good old soap and water and scrubbing with an old toothbrush will get them all cleaned up. Don't forget, you can always get them polished and made into jewelry. Have fun!

One last word of caution...

You are in a high desert environment and are sharing that with the local wildlife. Rattlesnakes have occasionally been seen in this area. When you are wandering across Garnet Hill, use your shovel or hand tools to carefully turn over any rocks that may be sheltering a snake. These creatures prefer to leave you alone - unless you stick your hand in their face. A little bit of caution is always a good idea.

Garnet Hill gem collecting

Garnet Hill is nationally known for its very dark colored garnets found in a flow banded rhyolitic volcanic rock. Two square miles of public land were designated as a public recreation area in 1970 to ensure continued public access to the site because of its recreational, rock hounding, and scientific study values.

Toquima Cave Pictographs

Toquima Cave pictographs

Burrowed in the Toquima Range in the Humboldt-Toiyabe National Forest, Toquima Cave holds massive cultural importance to Native Americans. This sacred site was utilized by the Western Shoshone tribes as a temporary dwelling between 3,000 and 1,500 years ago.

A large number of pictographs adorn the north and south walls of the cave. As one of many pictograph sites in Nevada, Toquima Cave and the surrounding 40 acres were added to the National Register of Historic Places in 2002.
