Facing the shallow stream, which is all that modern irrigation
reservoirs have left of the rushing Laramie River, are the stone walls
and barred windows and doors of the guardhouse, or prison, built in
1866. The upper floor was used largely by the post guard contingent,
while prisoners, regardless of the degree of their offense, languished
in the basement room where remains of a solitary cell suggests the
probable harshness of military penal discipline. Bricked-up windows and
doorway are evidences of later use of this structure for ordnance
storage.
