Description
Lawson Creek drains Rhone Glacier, an alpine glacier adjacent to the Taylor Glacier and flows into the west end of the west lobe of Lake Bonney. The stream flows through a well-defined, steep-sided channel with a moderate to steep gradient and step-pool morphology. Bed particles are unevenly arranged, rather than a flat pavement as in other stream reaches with similar gradients. Stream length: 0.3 km.
Environmental data
Hydrological, biological, chemical, and physical property measurements have been made for a number of McMurdo Dry Valley streams and lakes.
