The complicated drainage network that controls the quantity of water that enters the northern end of Lake Eyre is displayed in this view of the southwestern Simpson Desert. Three ephemeral creeks (Woodmurra from the west , Kallakoopah from the north, and Warburton from the east, northeast) are visible near the left center of the frame (northern end of Lake Eyre). These creeks are identifiable as dark (more vegetation), winding features. The very dark areas within Lake Eyre are limited areas of standing water. The elongate, narrow structure, oriented north-south, near the bottom of the image is the Warburton Groove, which is a channel that carries water from the northern part of Lake Eyre to the southern bays. The subtle dark, parallel lines north and east of Lake Eyre are sand ridges that are part of the large Simpson Desert. Numerous dry lake beds are visible, as they are reflective and contrast with an otherwise sandy environment.
