My boyfriend had told me about seeing what he thought were servailence drones thrugh the past winter, which would not surprise me due to the glen canyon dam being 2 miles away. makes sense to photograph it for security. i only saw the craft last night and tonight. i thought it was a personal drone at first with the flickering lights and unsteady movement, bouncing up and down, swaying back and forth. but it appeared to be extremely high in the sky and too far away for me to see a small drone so clearly, also. both nights it stayed in the sky for 2 hours, drones batteries dont last that long. so i took some photos and a short video and when i blew them up i was surprised to find it was a solid structure. i'll try to submit the originals as well as the enhanced photos.
