The icon is a picture of a wharf. The icon is in the shape of what appears to be a beat inside of a docking type of station. The boat looks to be held down by either ropes or chains to the bottom siding of the docking station.
This Wharf icon is made in Material Design style
developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 5,700 icons, all in the same style and quality.
