Landsat Reveals Scar of ‘Good Burn’ at Guadalupe Mountains

Pre- and post-fire images acquired with shortwave infrared (SWIR), near infrared (NIR), and red bands on Landsat 8’s Operational Land Imager sensor reveal a significant, 14,442-acre burn scar within the park’s high country. The burn scar appears red in the June 23 image. Lightning started the wildfire, and strong winds drove it to the Texas-New Mexico border.
