2. Essential Techniques for Locating Crystal-Bearing Rocks
When searching for crystals, three standard methods can be employed: exploring tailing piles from previous digs, identifying and following float, and excavating directly within the source pegmatite. These techniques can be used individually or in combination to enhance your chances of success.
2.1. Prospecting Tailing Piles
Tailing piles, the discarded rock and soil from previous excavations, can be a treasure trove for the observant crystal hunter. These piles often contain overlooked or discarded specimens that can reveal valuable insights into the area’s geology.
2.1.1. Advantages of Tailing Pile Prospecting
- Easy Access: Tailing piles are readily accessible and require minimal effort to explore.
- Potential for Overlooked Treasures: Previous prospectors may have missed valuable crystals due to mud coatings, imperfections, or lack of interest in certain types of specimens.
- Learning from Others: Examining the rocks and materials in the tailing pile can provide clues about the types of crystals found in the area and the techniques used by previous prospectors.
2.1.2. Tips for Effective Tailing Pile Prospecting
- Move Around the Pile: Shift your position to catch sunlight reflecting off flat surfaces, which could indicate a crystal face.
- Get Down Low: Change your perspective by getting closer to the ground, revealing crystals you may have missed while standing.
- Look for Color: Crystals coated with iron-based minerals may appear rusty, so pay attention to unusual colors.
- Poke Around the Sides: Check the edges of the excavation for pockets or seams that the previous prospector may have missed.
- Look for Float: Search for crystals that may have eroded from the pocket and accumulated in the tailing pile.
- Dig Through the Tailings: Crystals may be partially buried, so dig through the pile to uncover hidden specimens.
- Study What Others Were Into: Analyze the types of rocks and materials that the previous prospector was extracting to identify potential crystal indicators.
- Explore Large Excavations: Bigger holes suggest that the prospector found something significant, so focus your attention on these areas.

2.1.3. The Value of Imperfect Crystals
Don’t overlook crystals that may appear “boring” or imperfect. These specimens can still be valuable and offer insights into the crystal formation process. Remember, one person’s trash may be another’s treasure.
2.1.4. Examples of Tailing Pile Finds
Many remarkable crystals have been discovered in tailing piles, including:
- Milky Quartz and Fluorite Plates: Discarded by the original miner, these plates can be cleaned up to reveal stunning specimens.
- Fluorite Crystals: Often covered in pocket mud and dirt, these crystals can be found by carefully examining “dirt balls.” Fluorite crystals are denser than other rocks, so pay attention to the weight of the rocks you are extracting.

2.2. Finding and Following Float
Float refers to rocks or crystals that have weathered out of their original location and been transported by natural forces like glaciers, wind, and rain. By identifying and following float, you can trace these displaced specimens back to their source.
2.2.1. Understanding Float Movement
- Glacial Movement: Crystals moved by glaciers often exhibit broken, cleaved, or rounded corners due to the abrasive forces of the ice. These crystals may have traveled long distances and may not be directly related to the surrounding geology.
- Wind and Water Erosion: Wind and water can erode crystals from their original pockets and displace them downhill or radially away from the source. The original location of the crystals may have been partially or completely eroded over time.
2.2.2. Recognizing Buried Float
While it’s tempting to assume that float is easily visible on the surface, it is often buried beneath a layer of topsoil and organic matter. The boundary between the topsoil and the gravel layer is a common location for buried float.
2.2.3. Utilizing Float to Find Crystal Pockets
- Dig Test Holes: When you find promising signs on the ground, dig test holes deep enough to reach the boundary layer between the topsoil and the gravel.
- Explore the Source: If you find signs of float in a test hole, expand your excavation area in all directions to trace the float back to its source.
- Follow the Signs: Continue to follow the trail of float, typically uphill, until you reach the crystal pocket or seam still embedded in the pegmatite rock.
- Dig Strategically: If you find no signs on the surface but the area feels promising, dig test holes in likely locations. If you find nothing within a 2-3 foot diameter, move on to another spot.
2.2.4. Dowsing Rods
Some prospectors use dowsing rods, L-shaped rods held loosely in each hand, to detect the presence of crystals. The rods are believed to move when the user walks over an area with crystals. While this technique is not scientifically proven, some prospectors find it helpful.
A float dig. I was following signs up the hill (probably 10 feet here) digging only about 3-7 inches deep. Notice the pile of dirt on the right, this makes it ultra fast to fill in the hole once I’m done…literally 2 minutes. I often backfill the hole as I’m following the float. Notice the rocks on the surface above my digging, these are what you want to see, but in this case they are likely from another dig up the hill as they are not partially buried like Mother Nature would do
Digging for float involves following signs up a hill, excavating shallowly, and backfilling as you go.
2.2.5. Identifying Good Signs
Recognizing good signs is crucial for successful float prospecting. These signs can include:
- Flat Sides: Rocks with flat sides indicate that they had enough room to crystallize, suggesting the presence of a crack, seam, or pocket in the host rock.
- Quartz: Pegmatites are partially composed of quartz, so look for chunks of quartz either by themselves or mixed with Microcline/Feldspar.
- Microcline: Like quartz, microcline or amazonite is a good sign of pegmatite.
- Graphic Granite: Graphic granite is a type of pegmatite where crystals of quartz and feldspar grow together, often increasing in size within a single rock sample. This can indicate that you are getting closer to a crystal pocket.
- Combinations of Above: Finding a combination of these signs suggests that all the right ingredients for a pegmatite seam are present.
- Crystals: Discovering whole crystals or crystal fragments is a clear indication that you are close to the source.

2.2.6. Analyzing Tailings Piles from a Distance
When digging float uphill, leave the quartz or microcline chunks you find on top of your tailings pile near where you found them. If you lose track of the good signs or need a break, step back and analyze your findings from a distance. This can provide a new perspective and help you identify patterns or clues you may have missed.
2.2.7. Exploring Around Existing Digs
Another way to find crystals using the float technique is to explore around and downhill of existing digs. It’s likely that there is float around or below the pocket that the previous prospector has already located.
2.3. Prospecting Pegmatites
The most direct approach to finding crystals is to dig directly into pegmatites, the source rocks where crystals are most likely to be found.
2.3.1. Understanding Pegmatites
Pegmatites are coarse-grained igneous rocks that form during the final stages of magma crystallization. They are characterized by their large crystal sizes and often contain rare minerals and valuable crystals.
2.3.2. Pegmatite Formation
Pegmatites are formed by a lava flow of harder rock that contains high concentrations of minerals. These flows often extend across or into hillsides in a relatively straight line. During formation, mineralized fluid flows through cracks in the rocks. If there is enough open space, the fluid will crystallize. Pegmatites can open up to form pockets, pinch out, and then open up again along faults or cracks.
2.3.3. Identifying Pegmatite Boundaries
Pegmatite is often surrounded by gravel or dirt, as the surrounding rock decomposes over time. Knowing this, you can identify the boundaries of the pegmatite by the presence of gravel. Avoid digging test holes in areas with just gravel, but continue if you find chunks of pegmatite, quartz, or microcline.
2.3.4. Pegmatite Categories
Pegmatites can be categorized as chunks or solid masses. Digging into solid masses requires the most effort. Sometimes, a pegmatite will have a seam sandwiched between top and bottom plates of granite. In these seams, small pockets of crystals can be found. Follow these openings, as they may lead to larger pockets.
2.3.5. Extracting Pegmatite
Pegmatite chunks can be quite large and heavy, requiring pry bars, chisels, and hand sledge hammers to extract. Employ safe leverage and lifting techniques, and always wear eye protection.
2.3.6. Crystal Pockets and Fault Intersections
Crystal pockets are often found at the intersection of faults, where two pegmatites meet. Additionally, pockets can form where the pegmatite bends.
3. Geological Indicators for Crystal Hunting
Understanding geological indicators can significantly increase your chances of finding crystal-bearing rocks. These indicators provide clues about the presence of pegmatites, mineral deposits, and other formations that are likely to contain crystals.
3.1. Pegmatite Outcrops
Pegmatite outcrops are exposed areas of pegmatite rock that can be identified by their coarse-grained texture and the presence of minerals like quartz, feldspar, and mica. These outcrops are prime locations for finding crystal pockets and seams.
3.2. Mineral Staining
Mineral staining, such as iron staining or manganese staining, can indicate the presence of mineral deposits and crystal formations. The color and distribution of the staining can provide clues about the types of minerals present and the geological processes that have occurred in the area.
3.3. Rock Alteration
Rock alteration, such as weathering, erosion, and hydrothermal alteration, can create favorable conditions for crystal growth. Altered rocks may exhibit changes in color, texture, and mineral composition, making them easier to identify and explore.
3.4. Fault Lines and Fractures
Fault lines and fractures are zones of weakness in the Earth’s crust that can act as pathways for mineral-rich fluids. These fluids can deposit minerals and crystals in the surrounding rocks, making fault lines and fractures promising areas for crystal hunting.
3.5. Contact Zones
Contact zones are areas where different types of rocks meet, such as the boundary between igneous and sedimentary rocks. These zones can be geologically active and may contain a variety of minerals and crystals.
