Mountain Top Removal in Appalachia: What’s in your backyard?

SkyTruth’s new Mountain Top Removal visualization tool is now available to inspect active mining data for 74 counties in Kentucky, West Virginia, Tennessee and Virginia. The website can be accessed at The maps leverage tens of thousands of mining footprints, the result of SkyTruth’s mountain top removal (MTR) research. Before expanding to 74 counties, […]


30 Years of Mountain Top Removal in Logan County, WV

Last Friday, I posted a blog about our historical map showing the cumulative impact of mountain top removal coal-mining activity. At John’s request, I have begun using this data set to assess the expansion of observable mountain top removal (MTR) mining footprint since 2005, when the data set was last updated. I’ve used Logan County, […]


30 Years of Mountain Top Removal in Google Earth

Yay! We’ve got a new toy here at the lab! We’ve received a Google Earth Builder license! We’re excited because it will allow us to publish huge data sets that we were never able to publish before.     The first thing we’ve decided to publish is a historic map of the cumulative impact of mountain […]


Updating SkyTruth’s mountaintop removal mining dataset

In Appalachia, it is not uncommon to see the effects that mountaintop removal mining have on the surrounding ecosystems.  As someone living in the great Mountain State of West Virginia, one of the projects that caught my interest when I started my internship at SkyTruth was their work mapping the extent of surface mines in […]


Visualizing Elevation Change: Mountaintop Removal Mining

Here at SkyTruth, we are always looking for new ways to visualize the environmental impact of human activity, so we’ve been playing with LiDAR (Light Detection and Ranging) data and digital elevation models (DEMs). We thought it would be interesting, and potentially useful, to create a profile of the terrain of a mine before and […]
