**Title:** Rediscovering the Tepequém Mountain Range in Roraima, Brazil
**Summary:**
The Tepequém mountain range in Roraima, Brazil, was once a thriving diamond mining hub, attracting thousands of prospectors from the 1950s to 1989. The mining era created wealth for some, like Valdemar, who became a millionaire, but also left its mark on the environment. After mining was prohibited in 1989, the local community had to adapt and discovered new treasures in the region's natural beauty. Today, the area is being rediscovered for its:
* Over 20 stunning waterfalls
* Hiking trails (formerly mining paths)
* Scenic viewpoints, including a 1,100m-high plateau
* Unique flora and fauna, including a "Fountain of Youth" with mineral-rich, dark-colored water
The community has shifted from mining to ecotourism, embracing the region's true wealth: its unspoiled natural beauty.
