Steirische Kalkspitze, Mountain summit in Schladming, Austria.

Steirische Kalkspitze is a 2459 m summit on the Salzburg–Styria border in the western Schladminger Tauern, facing the slightly higher Lungauer Kalkspitze (2471 m) across the Akarscharte (2315 m). Both peaks close off the southern end of the Styrian Preuneggtal. The mountain is built largely of carbonate rock — massive and bedded dolomite and limestone marble — unlike the crystalline schists and gneisses of the surrounding range; quartzite outcrops at the very top.

The mountain was shaped by ancient tectonic movements and long-term erosion that formed the Schladming Tauern range. This geological process created the limestone structures visible in the landscape today.

The peak sits on the Styria–Salzburg border, and two long-distance trails cross the Akarscharte below it: the Zentralalpenweg (Austrian long-distance trail 02) and the Arnoweg. Because of these routes both Kalkspitzen are climbed often. Hikers can stay at the Oberhütte (1859 m), Giglachseehütte (1955 m) or Ignaz-Mattis-Hütte (1986 m).

Ascents run from Ursprungalm (1604 m) over the Znachsattel in 2½ hours, from Obertauern (1739 m) via long-distance trail 02 in about 5 hours, and from Hopfriesen (1040 m) past the Giglachseen in 5 hours, 2 of them from the Ignaz-Mattis-Hütte (1986 m). Near the summit the path demands sure-footedness and a head for heights.

The summit itself is made of Middle or Lower Triassic quartzite known as Lantschfeldquarzit, while the surrounding massif consists of dolomite and limestone marble. This rock sequence is inverted, with older layers lying above younger ones, and the boundary surfaces dip mainly eastward.
