''A. nelsoni'' are yellowish-brown or buffy-tan on the dorsal head and neck and outer surface of the limbs.  The tail is thicker than the other ground squirrels with fringes.  The males are slightly larger than the females with a length of {{Convert|234 - 267|mm|inch}} and {{Convert|230 - 256|mm|inch}}, respectively.  The summer and winter pelages are distinctive with the winter pelage being much darker.  These can be distinguished from the White-tailed squirrels by their larger size and more grey in their pelage.  Their skulls also vary in the size of the zygomatic arch (larger in Nelson's) and the inflated auditory bullae and nasal bones of ''A. nelsoni''. The upper incisors and first upper molars are also larger.<ref>"[http://animaldiversity.org/accounts/Ammospermophilus_nelsoni/ Animal Diversity Web: ''Ammospermophilus nelsoni'']" accessed 5 January 2015.</ref>

All are somewhat similar in appearance and behavior.  They are around {{cvt|14-17|cm|in}} in head-and-body length with a {{cvt|6-10|cm|in}} tail, and weigh {{cvt|110-150|g|oz}}.  The tail is somewhat flattened.  They have a single white stripe on both flanks and none on the face.  They live in burrows, which they dig for themselves.  They are [[diurnal animal|diurnal]], and do not [[hibernate]] (though they become less active during the winter), so they are fairly easily seen.
