“It was customary for the War department to set aside a military resrvation of 100 square miles; here, in addition to the usual rectangular ten miles square, the reservation was extended in a strip downstream for an additional four miles to include more Grand island timber.
Although the boundary was neither fenced nor posted, emigrants camping in the vicinity were often politely informed they were on the reservation and could not camp thereon. The fort was located, not in the center of the rectangle, but at a point two miles from its western boundary, or eight miles from the eastern line. Consequently, the largest camping area was just beyond the western line. The military was not often so fussy about camping to the east, and covered wagon camps would sometimes be strung out in that direction for miles.”
