By Dr. Keith Jackson - Geology PhD


It can be a real challenge to find and dig for geodes in Pennsylvania without the proper guidance. Knowing where and what to look for is key, and it’s not always easy to come by.

With the right know-how, a geode hunter could strike it rich! Geodes are an incredible natural phenomenon, formed over millions of years as water and minerals seeped into air pockets inside rocks.

We’ve done the hard work for you and scouted out some great spots in Pennsylvania where you can find these natural gems. From popular mining spots to hidden gems, only locals know about, we’ve got plenty of options for anyone looking for a successful geode hunt.

What Are Pennsylvania Geodes Anyway?

Geodes are awesome! They’re basically like little treasure chests – they look like plain, ordinary rocks on the outside but when you crack ’em open, you get a real surprise. Inside, they’re lined with beautiful crystals ranging from clear quartz to amethyst and other pretty stones.

We’ve written an article that describes what geodes look like to help you know what to look for.

These rocks form when gas bubbles get trapped in volcanic or sedimentary rock and slowly fill with minerals over time. So the next time you find an interesting-looking rock, don’t be too quick to judge it – it could be a geode just waiting to be split! Because of Pennsylvania’s remarkable geology, geodes can be easily formed.

The Types Of Geodes Found In Pennsylvania

Geodes come in various forms and are discovered in different parts of the world. The type of crystal inside a geode affects how much a geode is worth and its attractiveness. You can locate the following geodes here in Pennsylvania:

Armstrong County

Armstrong County river where you can look for geodes

Armstrong County is located in the Allegheny Plateau region of the state. It’s comprised of rolling hills and valleys, with a mix of both flat and hilly terrain. The county has numerous streams and rivers, including the Allegheny, Kiskiminetas, and Redbank Creek.

Geologically speaking, Armstrong County is part of the Appalachian Plateau physiographic province, which consists mainly of sedimentary rocks from the Paleozoic Era. The area is known for its rich deposits of coal and shale.

The county has a mix of both rural and urban areas, with some small cities such as Kittanning and Leechburg. Rural areas are primarily agricultural, with many farms scattered throughout.

Since most of the land is privately owned you will need to get permission to search but it’s worth it. There are a lot of great streams and creeks around that can be great places to start looking if you don’t want to go to a mine.

Make sure you’ve read up on the most recent collecting guidelines from the State of Pennsylvania before you bring anything home.

Where we found geodes in Armstrong County

Although geodes are all across the county, we’ve found that the following areas are excellent:

  • Old lead/zinc mines in North Vandergrift’s Gravel Bar Hollow stream bed.
  • Echo mine system.

Crystal Cave

Find geodes at Crystal Cave

Crystal Cave is a natural limestone cave located in Kutztown. It’s known for its unique geology, featuring a vast array of colorful crystals and stalactites, which makes it a must-visit if you’re looking for Pennsylvania crystals as well. The cave is situated on the Appalachian Plateau, an area of rolling hills and mountains characterized by its limestone bedrock. This terrain has allowed for the formation of many underground rivers and streams.

Geologically speaking, the cave was formed over hundreds of thousands of years from acidic rainwater that slowly dissolved away at the limestone bedrock. This process created large underground chambers and passageways filled with sparkling crystal formations. Visitors to Crystal Cave can explore these caverns on guided tours, which allow them to get up close to some of the most spectacular formations in the world. With its incredible beauty, Crystal Cave offers visitors a chance to learn about the geology and history of Pennsylvania’s Appalachian Plateau region.

Where we found geodes in Crystal Cave

You can find them in certain cave areas near the entrance and in some of the larger rooms.

Gravel Bar Hollow in Pennsylvania is a geologic wonderland. Located in the Juniata Valley, it’s a lush green valley with plenty of rolling hills and streams. The terrain is primarily wooded, with abundant trees, shrubs, and wildflowers. It’s also home to various wildlife, including foxes, deer, and wild turkeys.

The hollow’s geology is unique, too – it’s composed of gravel bars formed by centuries of erosion from the nearby Susquehanna River. These gravel bars are made of sandstone and quartzite and create an interesting landscape that looks like something out of an old Western movie! The geography here is diverse, too – steep hillsides with rocky outcroppings, meadows blanketed in deep grasses, and small creeks that meander through the area. Gravel Bar Hollow is a stunning spot to explore and take in the sights – it’s worth checking out if you’re in the area.

Where we found geodes at the Gravel Bar Hollow

You can find geodes along the banks of Susquehanna River. The geodes are typically located in gravel bars and islands eroded by the river.

Henvi’s Quarry

Henvi's Quarry in Delaware County

Henvi’s Quarry is nestled in the foothills of the Appalachian Mountains. The terrain is rugged and hilly, with a few flat areas. The quarry comprises limestone and shale rocks that are millions of years old. These sedimentary rocks have been weathered and shaped by wind and water, giving the quarry unique characteristics. The quarry’s geography is varied, with cliffs, deep ravines, and plenty of nooks and crannies to explore. The area around the quarry is heavily forested, so it’s a great spot for hikers looking to get off the beaten path.

Geologically speaking, Henvi’s Quarry offers a fascinating glimpse into Pennsylvania’s history. The sedimentary layers tell stories about how the region has changed over time. The limestone deposits indicate an ancient sea that once covered this region, while the shale indicates more recent changes in climate and erosion patterns.

Additional areas you should try

The area to hunt for geodes in Pennsylvania is vast, so we want to help you search. You should look into these key areas where geodes are frequently found:

Mines and mine dumps

Mines and mine dumps are great spots for geode-hunting. They’re often filled with interesting rocks that could be hiding a geode inside. Plus, they’re usually easy to access and open to the public, so anyone can find a gem. Geodes can form in all sorts of places, but mines and mine dumps are known for having especially unique specimens that are hard to find anywhere else.

The ores in these locations were formed over millions of years, which makes them home to some really cool geological formations. The heat and pressure from the ores can cause minerals like quartz and calcite to crystallize. This creates a hollow cavity inside the rock where you might find some amazing crystals!


Quarries are an awesome spot to score killer geodes, and for a good reason! They are prime real estate for geodes because they tend to be pretty remote, which means less foot traffic from collectors and a better chance of finding a hidden gem. Plus, quarries are frequently used for mining and excavation, so you might luck out and come across some new geodes that were just uncovered.

Another reason quarries are a solid choice for geode hunting is that they often have a diverse range of minerals and crystals in one location. This means you could stumble upon a geode filled with amethyst, quartz, or other gems all in the same spot. But don’t forget to do your research before heading out to a quarry! Some quarries are privately owned or may require permission to access.

Rivers and riverbanks

If you’re looking for any geode, you might want to head down to the riverbank! Rivers and their banks can be prime locations to find geodes because the flowing water can wear away the rock, creating natural pockets and formations where geodes can form. One of the biggest advantages of searching for geodes in rivers is that the water can help expose geodes that are partially hidden or buried in the ground. And since rivers often run through different rock formations and geologic regions, you might find a variety of geodes with different types of minerals and crystals in one area.

Another reason riverbanks are a great place to find geodes is that the water can help break up the rock, making it easier to find geodes already cracked open. This can be especially helpful if you’re not experienced in cracking open geodes yourself. Make sure you wear appropriate gear and watch your step, especially if the rocks are slippery or unstable. And, of course, be respectful of the environment and only take what you need.

Streams and creeks

If you’re on the hunt for some sweet geodes, streams and creeks are a great place to start! These waterways can be prime spots for geode collecting because the moving water can help wear away the rock, exposing natural pockets and formations where geodes can form. One of the benefits of searching for geodes in streams and creeks is that they tend to be less crowded than other areas, which means you might have a better chance of finding a hidden gem.

Another advantage of looking for geodes in these waterways is that the smaller rocks and pebbles can act like a natural sieve, making it easier to spot already exposed geodes. Just like with any other geode hunting, ensure you’re staying safe and being respectful of the environment. Always remember to leave the area as you found it.

Common Geode-Hunting Questions
