A quick search for "striped ground squirrel" turned up only one variety, the thirteen-lined ground squirrel. The animal in the photo has stripes like a chipmunk.
Look for stripes on the face: without them, it's probably a squirrel. Both ground squirrels and chipmunks have body stripes, so the face is a better indicator.
My University's (Minnesota) mascot is a gopher, but the physical mascot is a chipmunk/squirrel (debated) name Goldy Gopher - but it's definitely not a gopher. These rodents can be confusing!
It's both! That's the whole point - the same sequence of bytes can be interpreted as either an HTML web page or a JPEG image, and the page itself demonstrates both at the same time.
