Metal Frame Debris (LU004), Lake Union, Seattle, WA — main photo

Overview

Shipwreck City Data

This target has been classified as man-made metal infrastructure, resting in 35 feet of water and measuring roughly 6 feet by 6 feet. The metal structure rests on the lakebed and remains largely intact, with additional metal debris scattered around the site. Visible features include an angular metal frame with a 90-degree configuration and a metal element extending approximately 8 to 10 inches from one corner. The configuration may indicate a structural or support function, though we are unable to determine its original purpose.
