Not very darned big; population of about 20,000.  It has essentially two exits off of I-70 at each end of the town, about 4 miles apart.  It is pretty isolated, in a semi-desert setting of eroded rock hills.  Few trees, except where people have intentionally planted them in town.  Has a junior college.  It is at lat/lon 41.5889, -109.2232.
