The Middle Fork Chena River meanders across the northern portion of this terrain, anchoring a drainage network that includes Ottertail Creek and Sullivan Creek. This 2024 survey of the Big Delta area reflects a landscape defined entirely by its hydrography and township boundaries, with no roads or man-made structures recorded. The southern reaches are dominated by the elevation changes surrounding Blackshell Creek and Lohi Creek, while Anderson Creek cuts through the southwestern corner. These drainages provide the primary landmarks for navigating the interior, where the Teucher Creek valley further divides the eastern slopes. The map serves as a contemporary record of this unpopulated region, documenting the exact courses of these water bodies and their relationship to the established survey lines of T2N and T1N.
