USGS 7.5 minute Quad maps' datum
(OP)
Are USGS 7.5 minute Quad maps based on NAD27, NAD 83 or GEO84 projection datum?
Remember: The Chinese ideogram for “crisis” is comprised of the characters for “danger” and “opportunity.”

If no other files came with the image, then try looking at other websites that have metadata listed or allow downloading of the image with the collar still attached.
