The Spirit sol 676 photos show, among other things, an ancient walkway or roadway with culverts and tunnels underneath. The purpose of this project is such: I need someone to enhance the photo as best as possible, to show the walkway and tunnels as clearly as possible. Post the edited photo here. Join the forum, then find the "attachments" tag for this post, and upload the adjusted photo. Be sure to leave any information you want to be included for credit in the video.I have posted the original photo and a duplicate with arrows pointing out the tunnels. Please enhance the original photo.
