| Description: | |
Gravel Lake is an ~10m diameter circular depression surrounded by 1m high Glenade Sandstone walls along its eastern margin. The floor of the depression is composed of flat clasts of fine siltstone and shale debris derived from the overlying clastic sequence. A small stream sinks at the eastern margin in normal conditions and in flood conditions the water backs up to form a small pond. | |
