Yooperlite: The Mystery Behind Its Meaning, Surprising Benefits, and Unique Properties!

Are you looking for something special and unique to add to your rock collection? Look no further than Yooperlite. This mysterious rock found only in the Upper Peninsula of Michigan will amaze you with its glow-in-the-dark properties. It is a special type of syenite containing a mineral called sodalite that produces a soft blue-green glow when exposed to ultraviolet (UV) light. Whether you’re a science enthusiast looking for more information about these rare finds or someone interested in embarking on your own Yooperlite hunt, this article will help explain what makes these glowing gemstones so special.

What is a Yooperlite?

First spotted on the beaches of Michigan’s Upper Peninsula in 2017, Yooperlite is a type of fluorescent syenite that contains the rare blue mineral sodalite. Sodalite makes these rocks unique and gives them their luminescent properties. It emits a soft orange-yellow glow under ultraviolet light, making it a sight to behold.

The intensity of this glow can vary depending on the amount of Sodalite present in the rock, but the rocks will still glow regardless. These rocks were named after their home state’s nickname: “the U.P.” or “Yoopers”. Not only are they visually stunning, but they also have a fascinating origin story of being created by ancient lava flows.

How Did Yooperlites Form?

Yooperlites were formed through a combination of volcanic eruptions and glacial movement. They formed about a billion years ago when a spectacularly violent geologic period saw North America attempt to tear itself in two. The Midcontinental Rift formed, creating unimaginable volcanic eruptions and 360,000 cubic miles of lava – one eruption produced an ocean of lava more than 1,700 feet deep. Despite this activity, the rift ultimately failed to split North America, much of which lies beneath Lake Superior today. Near the modern shore of Lake Superior, a large body of magma hardened beneath the ground to form syenite containing Sodalite known as “glowdalites”.


The last ice age around 10,000 years ago scraped these glowdalites southward and dispersed them across the shores of the Great Lakes, leaving behind chunks of Yooperlite for us to find today. The combination of the glacial movement and subsequent weathering wearing away at the rock’s surface creates the perfect conditions for these rocks to be found.

The Yooperlite Story

Erik Rintamaki discovered fluorescent syenite pebbles along the shore of Lake Superior in Michigan’s Upper Peninsula and dubbed them “yooperlites”. California geologist Gabe Reyna identified them as Sodalites.

Erik’s story began 15 years prior when he taught his brother-in-law Jason Klein to find agates on Lake Superior. Inspired by literature from the Fluorescent Mineral Society, Erik invested in a cheap UV flashlight and discovered two small yooperlites that June. He found more Yooperlites up to 5 pounds in size with upgraded LED UV torches and shortwave lamps.

Guide to Finding Yooperlites

Yooperlites don’t need to be mined or quarried, unlike many gems and minerals. With the right equipment and knowledge, you can find these special rocks on the beaches and shorelines of Lake Superior. Let’s look at how you can start your hunt for Yooperlites.

Where Do You Find Yooperlites?

Yooperlites, first discovered in Michigan’s Upper Peninsula, can be found anywhere in North America. To increase the odds of finding Yooperlites, search for rocky shorelines free from cliffs or hills near their source in the Upper Peninsula.

Beaches with sugar sand should be avoided since stones are not likely to be found here. Limestone rocks indicate a low likelihood of finding Yooperlites. They would most likely be concealed under tons of locally eroded rocks. However, you should remember that taking anything from any National Park or area is illegal.

When to Find Yooperlite?

Yooperlites can be found year-round. Many areas near beaches are seasonal, so the best times for finding Yooperlites are in the Fall and early Winter when storms and waves from Lake Superior alter the shoreline daily. The weather is also mild during these seasons, with fewer bugs and tourists. Spring is also an ideal time as the ice from the lake and storms “flip” the beach, revealing fresh stones to check out. Furthermore, the Yooperlites emerge from the snow during spring and are more easily noticeable.

What Do You need to Find Yooperlite?

There are a few basic tools you’ll need to find Yooperlites:

Black Light UV Flashlight – A black light flashlight is essential for finding Yooperlites. You need a UV flashlight that emits longwave ultraviolet radiation (UV wavelength of 360 to 400nm)

A headlamp – A headlamp provides hands-free illumination when you’re making your way around the beach.


A sturdy bag – You’ll need a sturdy bag to transport and store any Yooperlite specimens you find, like a mesh or canvas sack or an Army surplus duffel bag.

Extra batteries – Bring enough batteries to last your entire collecting trip.

Glow Sticks – Glow sticks are an excellent way to mark the area where you find Yooperlites. It’s a great way to track which rocks have already been checked and which ones still need examining.

Map – A map of the area you plan to visit is especially helpful if it includes landmarks and other features.

Snacks and drinks – Bring plenty of snacks and drinks to keep you fuelled up for your treasure hunt.

These are the basic tools you need to find Yooperlites along the shores of Lake Superior. With these items in hand and some knowledge about where to look, nothing is stopping you from finding your Yooperlite specimens!


What to Wear When Looking for Yooperlite Rocks?

When searching for Yooperlite rocks, the key is to wear clothing that will keep you warm and comfortable while allowing you to move freely. The following items are recommended for your Yooperlite hunt:

  1. Footwear: Finding Yooperlites requires lots of walking, so bring comfortable footwear. Sturdy shoes or boots are ideal as they provide enough support for your feet while walking on rocky terrain. Ensure your shoes have enough traction, as you don’t want to slip or fall when exploring the shoreline.
  2. Clothing: Remember that function should be the main priority when choosing clothing for a Yooperlite rock-hunting adventure! Wear lightweight yet warm clothes for the cooler temperatures in Michigan’s UP. Choose items made from breathable materials like cotton or linen to stay cool and comfortable even during long hikes. A good option is layering clothes – you can easily adjust depending on the temperature. Don’t forget waterproof clothing, too, since beach weather changes quickly.
  3. Gloves: Wear gloves when searching for Yooperlites to protect your hands when picking up stones. Leather work gloves are a great option as they provide more protection while allowing you to feel the stones.
  4. Hat: A hat is essential when going out in search of Yooperlites. It will keep the sun out of your eyes while also providing warmth. Choose a waterproof hat or one with a wide brim to protect yourself from rain and sun.

You’ll be ready to go on your Yooperlite searching adventure with the right clothing and supplies. Remember to respect the environment and other beachgoers and follow safety guidelines.
