In the north-west there are basalt lava flows of the Batoka Formation, stretching from south of Bumbusi to the Botswana border. In the north-central area, from Sinamatella going eastwards, there are granites and gneisses of the Kamativi-Dete Inlier and smaller inliers of these rocks are found within the basalts in the north-west. The north and north-west of the park are drained by the Deka and Lukosi rivers and their tributaries, and the far south of the park is drained by the Gwabadzabuya River, a tributary of the Nata River. There are no rivers in the rest of the park, although there are fossil drainage channels in the main camp and Linkwasha areas, which form seasonal wetlands. In these areas without rivers, grassy pan depressions and pans have formed. Some of these pans, such as many of the pans in the Shumba area, fill with rainwater, while others, such as Ngweshla, Shakwanki and Nehimba, are fed by natural groundwater seeps. Many of the pans are additionally supplied by water pumped from underground by park authorities. Archaeological, historical and cultural sites People have lived in the region for tens of thousands of years, as attested by numerous archaeological sites ranging from early Stone Age to the historic era. Stone age foragers hunted and gathered in the region, leaving numerous sites with stone tools throughout today's park. They made engravings of animal hoofprints on sandstone rockshelter walls with some small rock paintings in the park's northwest. Iron-age people built large and small stone-walling sites in the park, such Mtoa and the Bumbusi National Monument. Information about the people who once lived in today's park is available online.
