Sentinel Range map.

Opalchenie Peak (Bulgarian: връх Опълчение, ‘Vrah Opalchenie’ \'vr&h o-p&l-'che-ni-e\) is the peak rising to 4,500 metres (14,800 ft) at the south extremity of the ice-covered Vinson Plateau, Sentinel Range in the Ellsworth Mountains, Antarctica. It has precipitous and partly ice-free south slopes, and is of low prominence except to the south, where two parallel ridges descend steeply southwestwards with Donnellan Glacier flowing in between and Mount Slaughter rising on the more southerly ridge.

The peak is named after the Bulgarian Volunteer Force in the 1877-1878 Russo-Turkish War and the Macedonian-Adrianople Volunteer Force in the 1912-1913 Balkan Wars, ‘opalchenie’ being the Bulgarian for ‘volunteer force’.
