I visited the beach at Port Blakely Mill on Bainbridge Island during a very low tide, and scanned a bunch of the unique industrial debris that is on that beach from the time that there was a mill here. These are some of the raw scans I generated from that outing. Broken posts, seaweed and lots of barnacle covered bricks. You can buy the game rez asset pack I made from this here: https://www.artstation.com/a/28866423
