The Outer Mullwitzkees is a glacier in the Venediger Group and is located in the core zone of the Hohe Tauern National Park , south of the main Alpine ridge and southeast of the Großvenediger . Together with the Zettalunitzkees , the lower part of the glacier, it is often referred to simply as the Mullwitzkees . To the west is the Rainerkees , which is also known as Inneres Mullwitzkees . In 2010 the glacier area was 3.03 km². The highest point of the glacier is at 3400 m at the Hohe Zaun , which is glaciated up to the summit area. The glacier tongue ended in 2009 at an altitude of 2690 m.

Most of the area of ​​the glacier is oriented to the south, only smaller areas in the lower area are exposed to the west, south-west or south-east. The Mullwitzkees is both a plateau and a valley glacier . The glacier is part of the so-called “Roof of God”, as the glacier plateau around the Großvenediger is also called. The border of the Mullwitzkees in this glacier plateau is drawn along the ice divisions , there are those to the Rainerkees in the west, to the Schlatenkees in the north and to the Frosnitzkees in the east. The Rainerhorn , Hoher Zahn and Kristallwand peaks protruding from the glacier surface form the corner points of these glacier borders from west to east. The Defreggerhaus is located west of the glacier . The Mullwitzkees drains into the Zettalunitzachbach and over this into the Isel , a tributary of the Drau .

From measurements carried out in 1998 it is known that the glacier does not have an overly powerful firn basin, the glacier thickness is mostly only between 50 and 70 meters. Because of this, and because of its south-facing orientation, it is to be expected that the glacier will react particularly sensitively to climate changes. For this reason, a project was started in September 2006 to investigate the relationship between the appearance of the glacier and the local climate. The annual mass balance for the 2009/2010 financial year was -490 millimeters of water equivalent . The surface portion of the Nährgebiets of the total area of the glacier (Accumulation Area Ratio, AAR) was 33.2%, the height of the equilibrium line (Equilibrium Line Altitudes, PA) was on 3105 meters.
