Long remained at Engineer Cantonment until October, when he returned eastward. He was accompanied by geologist Jessup, who had resigned from the expedition. Major Thomas Biddle, the keeper of the scientific expedition's official journal, had quarrelled with Long and was transferred to the military expedition late in 1819. Say, Peale, and Seymour spent the winter at Engineer Cantonment, as did Long's assistant James Duncan Graham, mapmaker and engineer William Henry Swift, six civilian members of the ''Western Engineer'''s crew, and a nine-man military guard.[

Long returned to Engineer Cantonment on May 27, 1820, accompanied by two new members of the party. Dr. Edwin James was to act as the expedition's surgeon, geologist, and botanist, thus replacing both Baldwin and Jessup. Captain John R. Bell was to keep the official journal, replacing Biddle.[

inventory undertaken in the United States".[ Expeditions such as Lewis and Clark's, while investigating the biota of the regions through which they passed, had only spent a short time in any one location. This was the case with Long's expedition in the second half of 1820: the need to cover distance quickly precluded the thorough investigation of any one locale. By contrast, the long stay at Engineer Cantonment allowed the party to study the local biota in detail, and to try to produce a complete inventory of the plants and animals of the area.][
The party's study of the local flora was limited. The loss of Baldwin en route to Engineer Cantonment had left them without a botanist; James, his replacement, did not arrive until a short time before the departure of the summer 1820 expedition. A total of 51 plants in 34 families were described, four of which were thought to be new to science.][

Frequent prairie fires prevented the growth of extensive woodlands: the river valley was characterized by scattered groves, the bluffs that bounded it were not densely wooded, and the prairie west of the bluffs was entirely treeless.

Archaeology
History records no further use of the Engineer Cantonment site after 1820. With the passage of years, the location was forgotten. During the 20th century, there were some desultory attempts to find it; the failure of these led to the general belief that the remains of the site had been obliterated by flooding and cutting of the river, by quarrying operations, or by other modern development.[

(NSHS) undertook an archaeological sampling survey in the greater Omaha area; it was thought that Engineer Cantonment and Fort Lisa might be found in the northern part of the study area. Planned improvements to a county road also called for an assessment of the impact on local cultural sites.[
While at Engineer Cantonment, Peale had produced several sketches of the camp and its surroundings. In early 2003, when the trees on the bluffs were bare, NSHS archaeologists saw that a stretch of the bluffs appeared to match Peale's drawing, including a wide ravine that Peale had depicted behind the camp. A trench was dug at the putative site, which produced limestone fragments, some discolored by burning, possibly remnants of a fireplace. Screening of dirt taken from the trench in the area of the burned limestone yielded, among other things, a brass button and a trigger guard fragment similar to items found at Fort Atkinson.][

followed by further excavation revealed a building measuring about east-west by north-south. The building was divided into two rooms by an interior wall, with a double fireplace in the middle. Fragments of ceramic tobacco pipes and tableware of a sort used around 1820 tended to support the conjecture that the site was actually Engineer Cantonment.[ The quality of the items also lent support to the conjecture: while tin cups and utensils would have been used by common soldiers, the wine bottles and painted porcelain found at the site were consistent with the upper stratum of society to which the expedition's scientists belonged.][
Peale's drawing appeared to show two buildings, one behind the other, near the mouth of a wide ravine. In the foreground, not far from the front building, the ''Western Engineer'' and several keelboats were moored in what appeared to be an oxbow cutoff of the Missouri. Although the oxbow was no longer extant in the early 21st century, trenching east of the two-room building discovered the edge of the harbor.][
The search for the second building depicted by Peale was unsuccessful. Initially, it was assumed that the building already discovered was the eastern of the two, so trenches were dug to the west and southwest. These yielded no evidence of a building. The archaeologists then investigated the hypothesis that the undiscovered building was east of the known one. Excavations in that direction yielded limestone fragments and a few artifacts, but nothing that could define a building. These eastern items were buried more shallowly than the remains of the known building, and it was conjectured that the remains of the western building had been covered and protected by the ]alluvial fan
