Southwestern Colorado is witnessing a fascinating initiative that combines cutting-edge technology with a rich geological history. From late August 2023, low-level helicopter flights have been traversing the skies of this region to conduct a detailed geological survey using advanced airborne geophysical technology. This project promises to expand our understanding of the Colorado Mineral Belt, an area renowned for its historic mining districts and diverse mineral wealth.
The Purpose of the Survey
The primary goal of this survey is to provide high-resolution images that deepen our knowledge of the geology underpinning the historic mining districts known as the "Colorado Mineral Belt". This extensive region is home to numerous types of mineral commodities. This new geological data, along with geologic mapping by the Colorado Geological Survey and USGS, will be combined to develop high-resolution 3D representations of the bedrock composition and structure to depths of 3,280 feet or more.
Survey Timeline and Coverage
The survey will be conducted in two phases. The first phase ran for approximately three months starting in late August 2023. The second phase resumed this spring and will continue for about six months, contingent on weather and wildfire conditions. The areas covered by the survey include:
Chaffee County
Gunnison County
Saguache County
Hinsdale County
Ouray County
San Miguel County
San Juan County
Dolores County
Montezuma County
La Plata County
This broad coverage ensures that a comprehensive geological picture is formed, benefiting a wide range of communities and industries across southwestern Colorado.
Flight Operations and Logistics
The helicopter flights will be based out of various regional airports, beginning with operations in the southwest survey area near Durango. Due to the nature of the work and the need to adapt to adverse flying conditions, the flight paths may shift with little warning. This flexibility ensures that the survey can be conducted safely and efficiently, maximizing the quality and coverage of the geological data collected.
Community Impact and Awareness
As these helicopters take to the skies, residents of the affected counties might notice an increase in aerial activity. These flights are part of a significant scientific endeavor aimed at enriching our understanding of the local geology. By mapping the subsurface, the survey will provide valuable data that could lead to new discoveries and advancements in mining, environmental studies, and land-use planning.
If you've been curious about the recent helicopter sightings, now you know that they are part of this important geological survey. Stay informed and share this information with your neighbors and friends to help spread awareness about the project.
