In this sketch, survey members are depicted completing common tasks of the expedition. The two figures in the foreground are gathering samples while figures attempt to summit in the background. On top of the peak are the cartographers mapping their location with a sextant on a tripod. Holmes used artistic license to show a foreshortened sense of space illustrating the range of duties the survey party was tasked with. The square outline identifies the cropping that would later be used by artists when making the engraving included in the 1873 Embracing Colorado Survey report, as seen below.
