Have you ever wondered about the ground beneath your feet? A new geologic map of the lower 48 states of the USA lets you explore this fascinating topic in detail.
What is a geologic map? It displays an area’s geological features, like different rock types, their ages, and where they are found. Geologists rely on these maps to understand the Earth better, including potential natural resources and hazards like earthquakes.
The US Geological Survey (USGS) has just released a detailed geologic map called The Cooperative National Geologic Map. This name reflects the teamwork behind the project, which involved over 100 existing maps from both USGS and state geological surveys.
Traditionally, creating such detailed maps took years. However, thanks to innovative automation techniques, the team completed this map in just three years. Sam Johnstone, a lead developer on the project, explained, “Ongoing mapping efforts continually make new discoveries. Our new method allows us to update our national map faster than ever before.”
This map is more than just a visual representation; it allows you to zoom in on specific locations and view geological data, even down to rock layers that date back to the Precambrian era—around 4.5 billion years ago.
Interestingly, this map isn’t only for professionals. It’s designed for the public, making it easy for anyone curious about their local geology to explore. Joseph Colgan, another USGS research geologist, states, “This map provides complete, analysis-ready geologic data for the nation. By making it available online, we aim to enhance educational engagement and foster public appreciation of geology.”
In addition, studies show that interest in geology is growing. A survey conducted by the Geological Society indicated that more than 60% of people want to learn more about their local geology. This trend highlights a greater fascination with the Earth’s history and resources.
As you dig deeper into your own backyard’s geological story, remember that this map reflects a collaborative effort to promote understanding and appreciation of our planet. By using modern technology, we now have the means to explore the Earth’s layers like never before.
