2020-06-07 - Euclid, OH - Other

So around 730 p.m. Jun 7th 2020. I decided to take my dog and telescope down by the rocks on lake erie. I then set my telescope up and began filming the horizon. I eventually came across something I thought was a refinery but now know its a huge rock with trees growing from it. So as im filming a square like object with rounded edges appears. It was moving around the speed of a boat maybe faster but it seemed to glide effortlessly about 10 to 15 feet above the water. The square had a dark outline in a cube shape but with rounded edges and was see through except the edges that outlined it. When it passed in front of the rock the outline seemed to darken as if the outlines were transparent or something. It hovered past the rock and about a mile further then eventually faded into the horizon.
