Description: NOTE: This image is a panorama consisting of 13 frames that were merged or stitched in PTGui Pro. As a result, this image necessarily underwent some form of digital manipulation. These manipulations may include blending, blurring, cloning, and color and perspective adjustments. As a result of these adjustments, the image content may be slightly different than reality at the points where multiple images were combined. This manipulation is often required due to lens, perspective, and parallax distortions.
