If you have experienced a sunset walk along the shores of Lake Superior, you probably can not notice the hidden treasures until you switch on a UV flashlight. Those ordinary grey stones may suddenly become alive in stunning yellow, orange, or red hues. These glowing stones are known as yooperlites, and discovering one is almost as secret as only nature knows it.
This article is intended for anyone interested in yooperlites from what they are, why they glow, to how you can locate them yourself on the lakeshore. Yooperlite hunting is an adventure even if you are starting out or simply enjoy nighttime beach walks.

¿Cuándo se fundó Yooperlite?
Yooperlite was discovered in 2017 by Erik Rintamaki, who found these glowing stones along the shores of Lake Superior and eventually named them “Yooperlites”. It not only made the world curious about his discovery but also brought a fresh wave of rock-hunting enthusiasm. A series of activities including guided gem, hunting tours, local events, and a community of collectors around this unique find appeared shortly. Nowadays, more adventurers are attracted to the northern lakeshore of Michigan to get the excitement of finding these luminous rocks themselves.


¿Cómo encontrar yooperlitas?
Buscar yooperlitas es una aventura al aire libre divertida y gratificante, y elegir el momento adecuado y prepararse adecuadamente puede hacer que la experiencia sea aún mejor. Si quieres encontrar estas piedras luminiscentes más fácilmente, el mejor momento para buscarlas es por la noche. La oscuridad hace que su fluorescencia resalte bajo la luz ultravioleta. Asegúrate de anteponer la seguridad. Es esencial contar con una linterna UV de buena calidad y gafas amarillas con protección UV que reduzcan la fatiga ocular. Y dado que muchas de estas playas se encuentran en zonas remotas con poca cobertura móvil, es más seguro y divertido explorarlas en grupo que ir solo.
