'Narrative of an Expedition into Central Australia' by Charles Sturt is an account of exploration in the heart of the Australian continent. Sturt vividly describes the continent's rivers, particularly the peculiarities of the Darling and the Murray, and the sudden floods to which they are subject. He also provides insight into the geological position of these rivers and their importance to the continent. Sturt's expedition encounters challenging terrain, scarce water, and dangerous plains, which put their journey at risk. Despite these obstacles, they persist in their quest to explore and map the interior, discovering new creeks and ponds along the way.
