Mawson Peak

Mawson Peak rises 2,745 meters above sea level on Heard Island, featuring a wide caldera and continuous lava flows from its southwestern slope.

The 1964 expedition led by Major Warwick Deacock achieved the first successful climb of Mawson Peak, using the schooner Patanela for transportation.

The Australian National Antarctic Research Expedition named this peak after Sir Douglas Mawson, an Australian geologist who explored the island in 1929.

Scientists monitor the volcanic activity through satellite imagery due to the extreme isolation of the peak in the southern Indian Ocean.

The mountain stands as the highest point under true Australian sovereignty, surpassing the mainland's Mount Kosciuszko by more than 500 meters.
