Neighbors in the campground

We are seeing a lot of certain neighbors at the campground...

When we first saw them, we thought they were some kind of chipmunk -- the way they moved, though the coloring was wrong.

The small ones are the size of a mouse, but with a slightly fuzzy tail.

You may be able to get a better idea of the size next to the fire pit/grill on our patio.

With the tail up like this, it really looks like the mannerisms of a chipmunk.

This is a smaller one -- they seem to be of two different sizes -- we think that this smaller size are this spring's offspring, and the larger ones are adults born in a previous year.

We asked the camp host, and they indicated that these are ground squirrels (https://en.wikipedia.org/wiki/Uinta_ground_squirrel). 

We are hoping that none of them get into our bays or into the house area of Gracie!
