I never made it to Lake Frome proper as we camped on a sand dune on the edge of Chambers Creek floodplain near the western shoreline of this ephemeral lake or salt pan. This stretches over a depression approximately 30 miles wide and 60 miles long It is the most southerly playa in an arc of ephemeral lake bodies that lie to the southeast of Lake Eyre in the Lake Eyre Basin. The smaller playa lakes including Lake Frome and Callabonna are sparse as they are fed only by the ephemeral creeks and rivers from the localised catchment areas of the northern Flinders Ranges.
In the dry season, Lake Frome exists as little more than a dry crust of salt and minerals. However, when rains fall in the northern Flinders Ranges, or the floodwaters creep in (usually the overflow from another saltpan to the north, Lake Callabonna), the depression becomes a lake again, providing habitat for a large number of animal and birds. However, significant runoff reaching Lake Frome is rare.
