Yooperlite Looking: A Information to Discovering Michigan’s Glowing Rocks

For those who’re planning a visit to the Higher Peninsula of Michigan or anyplace within the northern Nice Lakes area, Yooperlite looking is a extremely really helpful type of distinctive night time life.

There’s an simple attract to those luminous rocks, and the joys of discovering them within the wild is really satisfying.

Under, I’ll give you a complete information to Yooperlites.

I’ll supply insights into their discovery, delve into their geological historical past, discover the luminescent parts that make them distinctive, and likewise share a spread of suggestions drawn from my private experiences whereas looking for Yooperlites on the Keweenaw Peninsula.

What’s Yooperlite?

Yooperlite is a trademarked model of a kind of fluorescent rock that’s discovered alongside the shores of Lake Superior within the Higher Peninsula of Michigan (along with different areas as nicely).

The rocks are made up of principally syenite rock, which is analogous to granite, however they include a excessive focus of fluorescent sodalite. This mineral offers the rocks their distinctive glow when uncovered to ultraviolet gentle and makes them a primary catch for rock hounds.


Yooperlite: A quick historical past

Yooperlite has each a really lengthy and really brief historical past.

In the summertime of 2017, a second of curiosity led to a rare discovery by Erik Rintamaki, a gem and mineral fanatic hailing from Marquette, Michigan.

Armed with a UV gentle, he launched into a lakeside exploration alongside the shores of Lake Superior. To his amazement, that fateful morning revealed a few rocks aglow, as in the event that they harbored an inside molten core. Immediately, Rintamaki had unearthed a treasure beforehand unknown to the Michigan area.

However the place did the identify “Yooperlite” come from?

The nomenclature of those rocks bears a connection to the Higher Peninsula, affectionately generally known as “The UP.”

Inside this area dwell the proud residents generally known as Yoopers (as in “UPers”). Thus, the preliminary phase of the rock’s identify is a nod to those locals. The second half, “lite,” comes from the mineral “sodalite.”

Since Yooperlite is targeted on the UP and these rocks do exist elsewhere, some individuals desire to name them by their scientific identify (Fluorescent Sodalite-bearing Syenites) or by different nicknames, comparable to Glowdalites.

Personally, I similar to the thought of sticking with Yooperlites, as a result of it jogs my memory of the UP (a spot I’ve actually come to like) and the UP appears to be the first spot to search out them.

Yooperlites have been fashioned by way of volcanic exercise roughly 1 billion years in the past when the North American continent was splitting aside.

We name the occasion the Midcontinental Rift (or Keweenaw Rift) and it stands out as a result of it was essentially the most in depth rift in Earth’s historical past that by no means advanced into an ocean.

Throughout this time, huge quantities of lava was being produced, 1000’s of toes thick. Close to the trendy shores of Lake Superior in Ontario, a considerable physique of magma was attempting to breach the floor however this molten rock by no means made it.

As an alternative, it progressively cooled and solidified beneath the bottom, finally remodeling into quite a lot of granite generally known as “syenite.” This explicit syenite selection had an abundance of a mineral known as “sodalite,” which we’ll come again to in a second.

For roughly a billion years, these outstanding sodalite-filled rocks lay hid beneath the Earth’s floor.

Then, about 10,000 years in the past, the world witnessed the arrival of the final ice age, with colossal ice sheets carving a dramatic path throughout the panorama.

Of their relentless advance, these icy behemoths unearthed the Yooperlites from their historical resting place, transporting them southward.

In the end, these rocks discovered their present abode alongside the shores of what would later change into the Nice Lakes, the place they proceed to be found and admired to this present day.

In order that’s how they bought to Michigan however why do they glow?

Yooperlites exhibit fluorescence due to the distinctive properties of minerals like sodalite discovered inside them.

When uncovered to ultraviolet (UV) gentle, these minerals take in the high-energy UV photons and this elevates electrons to larger power states throughout the minerals.

As these excited electrons return to their decrease power states (aka rebound), they launch the absorbed power as seen gentle, creating the attribute glow that Yooperlites are identified for.

The place can you discover Yooperlites?

Folks have reported discovering Yooperlites in several elements of the Nice Lakes area, together with elements of Wisconsin and Minnesota. Nonetheless, the preferred spots appear to be the Keweenaw Peninsula and areas alongside the north east Higher Peninsula.

Talking with some locals, there positively are some frequent hotspots individuals have.

From what I used to be informed, an excellent Yooperlie hunter will wait till a storm rolls by way of that shakes the whole lot up and brings new Yooperlite to the shore after which they may have a discipline day that night. I received’t point out any of the native spots in order to not betray the pleasant locals however even when you don’t know the lesser-known spots there are fairly just a few broadly identified spots to search out Yooperlite.

Alongside the Keweenaw Peninsula you might have quite a lot of choices and we personally had luck with McLain State Park. We additionally tried Calumet Waterworks Park however we struck on the market and I believe some individuals had already cleaned home. For extra places across the Higher Peninsula, verify right here.

Lastly, when you can’t get to the seashore you will discover them in rock outlets. One of many best locations to get if you’re within the Houghton space is to take a look at the customer heart and present store on the Quincy Mine. They’ve a cool show and you should purchase them (the worth depends upon the scale).


My expertise discovering Yooperlite (and several other suggestions)

Arriving early could be value it you probably have an excellent gentle

We usually reached the seashore roughly 20 minutes earlier than sundown, and it wasn’t unusual to identify one or two fellow fanatics already engaged of their quest.

Previous to sundown, if outfitted with a sufficiently highly effective black gentle, Yooperlites are actually discoverable, albeit with a better stage of issue.

Discovering your first Yooperlite — as you witness a seemingly unusual stone rework right into a radiant spectacle — is an unforgettable expertise and immediately addictive.

On our first outing, we discovered ourselves dedicating a stable hour or so to the pursuit, though it’s solely potential we might have continued for for much longer if we didn’t produce other plans that night, comparable to attempting to find the northern lights.

You may nonetheless discover them if trailing behind individuals

Even when you’re trailing behind somebody, following of their footsteps, there’s nonetheless an excellent likelihood of constructing substantial finds.

It’s a difficult process for anybody to meticulously study and search by way of all the 1000’s upon 1000’s of rocks, so that you’ll prone to nonetheless be capable of discover one thing.

A 365 nm UV gentle is preferable however you possibly can nonetheless get by with a 395 nm

The prevailing recommendation usually suggests {that a} 365 nm UV gentle is notably superior to a 395 nm one for Yooperlite looking. Personally, I discovered myself favoring the 365 nm UV flashlight, primarily because of the enhanced glow of the rocks.

Nonetheless, throughout my “time within the discipline,” I didn’t observe a considerable disparity by way of detecting Yooperlites when utilizing both the 395 nm or the 365 nm UV gentle.

In each circumstances, I might readily discern the glowing specks of glowing sodalite.

It’s very seemingly that the standard of my 365 nm flashlight was not optimum (it was like $15), nevertheless it’s reassuring to know {that a} 395 nm black gentle can nonetheless successfully illuminate Yooperlites.

Which ever means you go, be sure to have an additional set or two of batteries as a way to proceed on by way of the night time, particularly when you’re having quite a lot of good luck.

Yooperlite hunting

A rock scooper and extra highly effective UV gentle will make the hunt much less bodily demanding

I discovered myself fairly fatigued (and lightheaded) from continuously crouching and getting up throughout our Yooperlite hunts.

Our use of small black lights pressured me to rise up near the rocks, and the absence of a rock scooper additional added to the trouble.

Many different rockhounds on the seashore have been outfitted with stronger black lights and rock scoopers, sparing them from the necessity to steadily bend over.

For those who’re actually dedicated to spending ample time looking for Yooperlites, I like to recommend investing in these instruments, because it appeared to make the method considerably extra environment friendly and fewer bodily demanding.

Yooperlite hunting

Be ready to search out some bizarre stuff

Together with your UV gentle, you’ll discover extra than simply Yooperlite.

You’ll discover that some rocks even have a sure glow about them though it’s totally different from the orange glow of the sodalite.

You additionally would possibly come throughout trash and random discarded oddities.

You should use this as a possibility to assist clear up the shore but in addition be conscious of the stuff you is likely to be grabbing together with your hand as chances are you’ll not wish to come into contact with sure issues. For instance, I got here throughout a random Q-tip.

Take a word of the place your flip off on the seashore is

You’re going to be wandering round at night time however fortunately, it’s fairly straightforward to navigate as you’re simply strolling alongside the shoreline, in all probability in a single path after which coming again. It might be exhausting to get actually “misplaced” nevertheless it’s potential you can wrestle to search out your flip off level again to the parking zone.

I’ve heard of individuals utilizing glow sticks to mark the flip off level which may very well be useful when you’re someplace that’s difficult to establish. Nonetheless, we have been capable of often simply word a big stone or driftwood that helped us keep in mind the place to go.

It is going to even be useful to have an everyday white gentle or purple gentle that will help you navigate when not utilizing your black gentle (headlamps are additionally useful).

Mountaineering boots are a good selection

We opted to don mountain climbing boots with waterproof capabilities, enabling us to place ourselves the place the waves washed up on shore. This positioned us in proximity to what’s seemingly essentially the most ample assortment of stones, because it represents the freshest deposit of rocks at any given time.

I’ve additionally come throughout tales of people wading into the water throughout their Yooperlite quests, so the strategy can differ relying in your stage of dedication and adventure-seeking spirit.

Mountaineering boots additionally aid you higher navigate the rocky shores which may very well be more durable with skinny tennis footwear.

Carry a bag

You’ll positively need a reliable bag to maintain all of your found rocks safe, as Yooperlite looking can yield fairly a group. That is additionally the place you possibly can hold some snacks and water as you’ll be stunned how rapidly you possibly can work up some thirst and an urge for food attempting to find rocks.

Investigate cross-check the legislation

On the time of this publish, it appears to be like like Michigan legislation means that you can gather as much as 25 kilos of rocks per yr from state parks however be sure to confirm the legality of what you’re doing. Some websites (like Pictured Rock Nationwide Lakeshore) might not permit rock amassing and also you additionally have to be cautious about stepping onto non-public property.

There’s an excellent likelihood it should get chilly when on the market so having further layers is sweet. On one night time we went out it wasn’t dangerous in any respect. Nonetheless, I at all times like having a puffer jacket when heading out to a lakeshore like this at night time since you by no means know what the wind goes to be able to.

Search for patterns within the rocks

We seen a putting similarity amongst a lot of the rocks we encountered – a grey look with black speckles. So one efficient technique is to focus on rocks that resemble those you’ve already gathered, though it’s value noting that there could be variability with these rocks.


Closing phrase

Our Yooperlite hunt was undoubtedly one of many highlights, no pun supposed, of our time within the Higher Peninsula.

It’s a type of peculiar discoveries that unexpectedly turns into fairly addictive. If I lived on this space, I might simply see myself making it an everyday pastime.

There are little question some spots which are hotspots, not as a result of they obtain an additional deposit of those rocks however as a result of solely seasoned fanatics know how you can entry and uncover them. However there are additionally many well-known seashores alongside the coast within the Keweenaw Peninsula that appear like a great place for the typical newcomer.

I hope the wealth of knowledge and suggestions offered on this article will equip you to completely respect, get pleasure from, and finally construct your individual assortment of those fascinating stones whenever you discover the Higher Peninsula of Michigan!
