What's up SUF fam. I recently went fishing with my Omnia app. I don't have any electronics so it shows me water depth and underwater contour changes. I had to break out my " Knockoff Nalgene bottle tote'n wanna be environmental science major days" to remember how to read the contours.
So, I thought not everyone may understand what they are looking at. On the 3D image pics you can mentally flip the image and imagine it as a hole or valley or you can imagine it covered in water as a cliff or mound all depending on the depth number listed on the contour line... The main thing to remember is... The closer the lines the steeper the slope like a ledge and the further the lines the more gentle the slope. Hope these help...

Spooky spooky... While at an oddities museum in Savannah, Georgia (Graveface Museum) they had a cabinet of "haunted\ cursed dolls" I have included the time stamps showing that these were taken less than a minute apart... The first photo was of the paper mache head. Notice that it is quarded considerably towards the door... The second picture is of me taking a photo of the whole cabinet... Notice the paper mache head....it's turned looking straight at me. I did not notice this until that night going through the photos.on my phone. The next day I showed the staff and they said that they have stuff like that all the time. They also said that the cabinet is glued and screwed shut to prevent anyone from touching the items... Stay spooky.
