I have a GeoTIFF layer (downloaded from US Dept of Interior) that is US population density. The metadata claims it is in EPSG:4267, which isn't even intended for use in that part of the world. (east end is at -52°, I think). If I add this layer to a map containing the world boundaries (layer source - Natural Earth, CRS = 4326), the two layers look like this (Natural earth admin boundaries on the bottom):
How do I go about figuring out the the CRS for the population density layer?
